Purpose Raymarine DSM300 Digital Sounder Modules provide echo sounder data that can be displayed on Raymarine E Series, C Series, and hsb2 PLUS (Pathfinder) Series display units. DSM300 Digital Sounder Modules are intended for recreational depth finding and fishfinding purposes. Echo sounder systems require an appropriate Raymarine transducer unit and inter-connecting cable. This manual contains very important information for installing your DSM300 and transducer. To obtain the best results in operation and performance, please read this handbook thoroughly. Raymarine's Technical Services representatives or your local dealer will be available to answer any questions you may have. SAFETY NOTICE This equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so can result in personal injury and/or navigational inaccuracies. In particular: CAUTION: High Voltage The DSM300 contains high voltages. Adjustments require specialized service procedures and tools only available to qualified service technicians ­ there are no user serviceable parts or adjustments. The operator should never remove the cover or attempt to service the equipment. CAUTION: Transducer Cable Removing the transducer cable from the rear of the DSM300 while the sounder module is powered on can cause sparks. Only remove the transducer cable after power has been removed from the DSM300. As with any electronic device, be sure the sounder module is mounted where it is well ventilated and free from gasoline fumes. If the transducer cable is accidentally removed while the DSM300 is powered on, remove power from the sounder module, replace the transducer cable, and then return power to the module. As a safety feature, the DSM300 only recognizes that the transducer is connected at power-up. 6 DSM300 Installation Manual EMC Conformance All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment.

It is very important that you complete the owner information and return the card to the factory in order to receive full warranty benefits. 7 Chapter 1: DSM300 Installation 1.1 Introduction This chapter provides details for mounting the DSM300 and connecting to the display. For the system to display depth, water temperature and speed, you must install the transducer type(s) capable of transmitting the appropriate data. Transducer information is provided in Chapter 2. Planning the Installation Before you install your system, plan the installation, considering: · Correct transducer for your application, as described in Section 2.1 · Location of the sounder module, as described in Section 1.3 · Cable Runs, as described in Section 1.5 EMC Installation Guidelines All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment. Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: · Raymarine equipment and cables connected to it are: · At least 5 ft (1.5 m) from any equipment transmitting or cables carrying radio signals, e.g., VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 7 ft (2 m). 8 DSM300 Installation Manual · More than 7 ft (2 m) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. · The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V and starter motor transients can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. · Raymarine specified cables are used. Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manual. · If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position. Suppression Ferrites The following illustration shows typical cable suppression ferrites used with Raymarine equipment. Always use the ferrites supplied by Raymarine. D3548-3 Figure 1-1: Typical Suppression Ferrites Connections to Other Equipment If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite must always be attached to the cable that is closest to the Raymarine unit. Chapter 1: DSM300 Installation 9 1.2 Unpacking and Inspecting the Components Unpack your system carefully, to prevent damage to the equipment. Save the carton and packing, in case you need to return the unit for service. Check that you have all the correct system components: Power Cable, 3m part no. R69053 Digital Sounder Module, part no.

Mount the DSM300 where it is: · · · · protected from physical damage and excessive vibration protected from prolonged exposure to rain, salt spray and direct sunlight well ventilated as close to the transducer as possible Do not locate the DSM300: · in the engine compartment · on the main console When planning the installation, the following should be considered to ensure reliable and trouble free operation: · Access: There must be sufficient space below the unit to enable cable connections to the panel connectors, avoiding tight bends in the cable. · Interference: The selected location should be far enough away from devices that may cause interference, such as motors, generators, and radio transmitter/receivers. (See the EMC guidelines earlier in this chapter.) · Magnetic compass: Mount the unit at least 3 ft (1 m) away from a magnetic compass. · Cable runs: The unit must be located near a DC power source. The power cable supplied is 10 ft (3 m). · Environment: Good ventilation is required to prevent the unit from overheating. CAUTION: Do Not Remove the Transducer Cable Removing the transducer cable from the DSM300 while power is turned on can cause sparks. As with any electronic device, be sure the sounder module is mounted where it is well ventilated and free from gasoline fumes. Chapter 1: DSM300 Installation 11 1.4 Mounting the Sounder Module The DSM300 can be mounted either above or below deck using the supplied hardware. To allow for ease of cable connection, mount the sounder module so that the cables hang below the unit. 1.65 in 3.46 in (88 mm) (41.8 mm) Weight: 2.2 lbs (1.0 Kg) 9.96 in (252.9 mm) Compass Safe Distance: 39 in (1 m) 2.43 in (61.7 mm) D7468-1 9.51 in (241.6 mm) 10.76 in (273.3 mm) 7.37 in (187.2 mm) Figure 1-2: DSM300 Dimensions To mount the DSM300: 1.

Figure 1-3: Properly Mounted DSM300 7469-1 14 DSM300 Installation Manual 1.5 Cable Runs Consider the following before installing the system cables: · You will need to attach power, transducer, and display cables. · All cables should be adequately secured, protected from physical damage, and protected from exposure to heat. · Avoid running cables through bilges or doorways, or close to moving or hot objects. · Avoid sharp bends. · Use a watertight feed-through wherever a cable passes through an exposed bulkhead or deckhead. · Secure cables in place using tie-wraps or lacing twine. Coil any extra cable and tie it out of the way. You will need to run the following cables: · Power cable, supplied with the unit. This 10 ft (3 m) cable has a connector plug at one end for connecting to the sounder module, and 3 wires at the other end for connecting the power supply. The power cable may be extended by up to 60 ft (20 m) using a wire gauge of AWG 12 or greater. The DSM300 is intended for use on boat's DC power systems rated from 10.7 V to 32 V. · Display cable, used to connect the DSM300 to a display unit. A 3m-long cable is included for connecting to a C Series display. Connection cables for E Series or hsb2 PLUS (Pathfinder) Series displays, or longer C Series cables, must be purchased separately. See Table 1-1 "Cable Options" on page 9 for a list of available display cables. · Transducer cable, supplied with the transducer. This 30 ft (10 m) cable has a connector plug (with an outer nut that you must attach) at one end for the sounder module or extension cable. Optional extension cables are listed in Table 2-1 "Accessories" on page 25. CAUTION: Do Not Cut or Splice the Transducer Cable · There is high voltage on the transducer cable. Splicing could create a safety hazard. · Cutting the transducer cable severely reduces sonar performance. If the cable is cut, it must be replaced--it cannot be repaired. · Cutting the transducer cable will void the warranty and invalidate the European CE mark. Chapter 1: DSM300 Installation 15 1.6 System Connections The connector panel provides the following connection sockets: · T/D, 7-pin socket for connecting to the transducer · HSB2, 4-pin socket for connecting to a C Series or hsb2 PLUS Series display · POWER, 3-pin socket for connecting to boat's DC power systems rated from 10.7 V to 32 V and one RF ground (screen) connection · SEATALK HS, RJ-45 socket for connecting to an E Series display C Series or hsb2 PLUS Transducer 10.7 to 32 VDC E Series Display D7464-1 Figure 1-4: DSM300 Connector Panel CAUTION: To protect exposed pins, please place the attached dust cover over the socket (4-pin or RJ-45) to which you are not connecting a cable. The following sections detail the connectors used when installing the DSM300. DC Power Connection The DSM300 is intended for use on boat's DC power systems rated from 10.7 V to 32 V. The power connection to the unit should be made at either the output of the battery isolator switch or at a DC power distribution panel. Power should be fed directly to the DSM300 via its own dedicated cable system and protected by a thermal circuit breaker or fuse on the red (positive) wire that is installed close to the power connection. DC power is connected at the 3-pin POWER connector on the unit's connector panel. The connector (viewed from the outside) and pin functions are shown in the following diagram and table. 16 DSM300 Installation Manual 1 2 D6162-1 3 Figure 1-6: Power Connector Pin No. 1 2 3 Function Color Battery positive (12/24/32 V systems) Red Battery negative Shield (drain wire) Black No insulation The RED wire must be connected to the feed from the positive (+) battery terminal and the BLACK wire to the feed from the negative (­) battery terminal. The shield wire (drain) should be connected to the boat's RF ground. See "Ground Connection" on page 17. Install a quick blow 8 amp fuse on the red (positive) wire. CAUTION: If the power connections are accidentally reversed the system will not work. Use a multimeter to ensure that the input power leads are connected for correct polarity. There is no power switch on the DSM300. The unit turns on when the power cord is attached to boat's power and plugged into the POWER connector on the connector panel. Note: You should locate the DSM300 so that the power cord can be easily removed, if necessary. If the sounder is placed in a difficult-to-reach location, Raymarine strongly suggests installing an on/off switch on the DSM300 power cord at a point where it is easily accessible. Chapter 1: DSM300 Installation 17 Transducer Connection A 30 ft (10m) cable is supplied with the transducer. For details see "Transducer Cable" on page 26. The connector pins are shown in the following diagram, together with the connections and wire colors; this is information is provided as an aid to fault diagnosis. 5 2 1 7 6 4 3 D4850-2 Figure 1-7: DSM300 Transducer Connector Pin No Function 1 2 3 4 Speed Temp Shield Sense Color Red White Drain Green Pin No Function 5 6 7 Speed/Temp Ground + Depth ­ Depth Color Brown Blue Black Ground Connection It is important that an effective RF ground is connected to the system. A single ground point should be used for all equipment. You can ground the DSM300 by connecting the drain wire (shield) of the Power Input cable to the boat's RF ground. If you need to extend the wire, the extension wire should be an 8 mm braid or AWG 10 multi-stranded cable. If your boat has a dedicated ground strap available, you can alternatively attach it to the ground wing nut on the rear panel of the module. If your boat does not have an RF system, connect the drain wire to the negative battery terminal. The DC system should be either: · Negative grounded, with the negative battery terminal connected to the boat's ground. · Floating, with neither battery terminal connected to the boat's ground. 18 DSM300 Installation Manual This system is not intended for use on "positive" ground vessels.

If you are replacing an old DSM250 with a new DSM300 in an existing C Series network, you will need to install the supplied 4-pin to 3-pin hsb2 adapter. Connect the 4-pin end of the adapter to the DSM300 and then connect the 3-pin end of the DSM cable to the DSM300. Unlike the DSM250, however, the DSM300 network connection is internally terminated. When replacing a DSM250 with a DSM300, DO NOT USE the hsb2 Inline Terminator that was connected to the DSM250.

When using the DSM300 with an hsb2 PLUS Series display, connect the supplied 4-pin to 3-pin hsb2 adapter between the DSM300 and the network cable. The hsb2 system must be terminated at both ends of the network. If a PLUS Series display is the last device on the network, an inline terminator is installed on the cable where it connects to the display. The network connection in the DSM300, however, is internally terminated; it does not require an inline terminator. Because the DSM300 is internally terminated, it must be installed at the end of the hsb2 network. You must NOT use an inline terminator on the DSM300 end of the network. If an hsb2 splitter is used, you must connect it to a display and not to the DSM300.

This chapter describes the transducers that are available for use with the DSM300. This chapter also provides general information for installing the three main types of transducers: transom mount, thru-hull and in-hull. Specific instructions for installing your particular model are included with your transducer. 2.1 Selecting the Correct Type of Transducer Before you start the installation, check that you have the correct transducer for your application. Applications Transom Mount Transducers are recommended for personal watercraft and powerboats with outboard, inboard-outboard and jet drives. They are NOT recommended for large or twin screw inboard boats. · Adjusts to transom angles from 3° ­ 16°. For angles greater than 16°, a tapered plastic, wood or metal shim will be needed. · Designed for operation from 5 ­ 58 m.p.h. (4 ­ 50 knots). Thru-Hull Transducers are recommended for boats with straight-shaft inboard engines. In-Hull Transducers are recommended for fiberglass hulls, especially in high speed power boats and racing sailboats. Materials Plastic housings are recommended for fiberglass or metal hulls. Bronze housings are recommended for wood or fiberglass hulls. Stainless Steel housings are recommended for steel or aluminum hulls. Notes: (1) Installation of a bronze housing in a metal hull requires using of a fairing, available from your Raymarine dealer. (2) Never install a metal housing in a vessel with a positive ground system. 24 DSM300 Installation Manual The DSM300 can be used with any of the following transducers: Mounting Method Transom Part No. (Model) E66049 1, 2 (M260) E66078 3 (M256) E66019 (ST69) E66054 (P66) Thru-Hull E66013 (P319) E66014 (B117) E66015 (SS555) E66076 4 (R99) E66024 5 (B256) E66033 5 (B260) E66053 4 (SS560) E66018 (ST600/B120) E66030 (ST600/P120) E66056 4 (B744V) Sensor Type Depth Depth Speed, Temp Depth, Speed, Temp Depth Depth Depth Depth Depth, Temp Depth, Temp Depth, Temp Speed, Temp Speed, Temp Depth, Speed, Temp Max.

In addition to improving sounder performance at all speeds, the fairing allows better fitting to the hull and dramatically increases the sealing surface. (2) This information was current as of the date this handbook was printed. New transducer models are constantly becoming available. Check with your dealer for the most current list. 26 DSM300 Installation Manual 2.2 Transducer Cable A 30 ft (10m) cable is supplied with the transducer. The transducer cable may be extended up to a maximum of 60 ft (20 m) using optional extension cables. The transducer cable connector has a nut that has been removed to aid installation. To allow you to complete the installation without cutting the cable, ensure that any holes you drill are large enough to accept the connector, with the nut removed. After the cable has been run through the holes, this nut must be attached before the cable can be connected, as described in Transducer Cable Connections. CAUTION: Do Not Splice the Cable Do not cut the transducer cable or remove the connector. Do not try to shorten or splice the cable. If the cable is cut, it cannot be repaired. Cutting the cable will also void the warranty. · For a Transom mount installation ­ route the cable up and over the top edge of the transom as shown in Figure 2-2 . Secure the cable using cable clamps (available from your local marine equipment supplier). If you do not want to expose the cable on deck, you may drill a hole 13/16" (21 mm) through the transom for the cable (with connector attached). To seal the opening, use a feed-thru cap where the cable passes through the transom. · For either type of installation ­ run the cable through the interior of the boat. · If the 30 ft (10 m) cable is not long enough, extension cables are available from your Raymarine dealer. See Table 2-1 on page 25. Total cable length from the transducer to the DSM must not exceed 60 ft (20 m). When you attach the extension cable, be sure that the connections are watertight. Use Dow Corning DC-4 or an equivalent sealing compound to protect the connector assemblies. CAUTION: Do not pull on the cable as this can damage the transducer wires. Transducer Cable Connections The transducer cable connector (and Y-connector, if supplied) has a nut that has been removed to aid installation. To allow you to complete the installation without cutting the cable, ensure that any holes you drill are large enough to accept the connector, with the nut removed (approximately 13/16" or 21mm). Chapter 2: Transducer Installation 27 Before attaching the transducer cable, you will need to attach the connector nut and split ring. These items, plus a wedge tool, are included in the transducer packaging. Connector/cable Protrusion Mounting groove Nut Split Split ring Wedge tool D5256-1 Figure 2-1: Assembling the Transducer Connector To attach the transducer cable connector: 1. Slip the nut over the connector cable end. Push it past the connector and over the cable. 2. Insert the wedge tool into the groove in the split of the split ring and slide the wedge tool until its squared end is flush with the larger edge of the split ring. 3. Slip the split ring and wedge tool over the connector body until aligned with the mounting groove on the connector. 4. Remove the wedge tool and seat the split ring in the mounting groove, making sure the connector protrusion falls into the split. 5. Slip the nut forward until it stops. Twist until the protrusions on the inside of the nut align with the grooves on the split ring. 6. Slip the nut forward and snap into place. 28 DSM300 Installation Manual The transducer cable is attached to the 7 pin male connector on the DSM. How you connect the cable to the unit depends on the type of transducer you have installed: · Combined depth/speed/temp transducers have a 7 pin female connector. Attach the transducer cable connector directly to the sounder module. · Combined speed/temperature transducers have a 3 pin female connector that requires the use of an additional Y-shaped cable (Raymarine part number E66022) to attach to the 7 pin connector on the DSM300. This Y-cable is included with your speed/temperature transducer. Attach the 7 pin female connector on the Y-cable to the sounder module, and then attach the transducer cable to the 3 pin male connector on the Y-cable. · Depth-only transducers have a 7 pin female connector. Attach the transducer cable connector directly to the sounder module. If being installed in conjunction with a speed/temperature transducer, attach the Y-cable's 7 pin female connector to the sounder module, and then attach the transducer cable to the 7 pin male connector on the Y-cable. Note: If your system requires both a Y-cable and a transducer extension cable, ensure that you connect the Y-cable to the sounder module and the extension cable to the transducer. CAUTION: Do not cut or splice the transducer cable: · There is high voltage on the transducer cable. Splicing could create a safety hazard. · Cutting the transducer cable severely reduces sonar performance. If the cable is cut it must be replaced, not repaired. · Cutting the transducer cable will void the warranty and invalidate the CE mark. CAUTION: Removing the Transducer Cable Removing the transducer cable from the rear of the DSM300 while the sounder module is powered on can cause sparks. Only remove the transducer cable after power has been removed from the DSM300. If the transducer cable is accidentally removed while the DSM300 is powered on, remove power from the sounder module, replace the transducer cable, and then return power to the module. As a safety feature, the DSM300 only recognizes that the transducer is connected at power-up. Chapter 2: Transducer Installation 29 Cable cover Cable clamps 2 in (50 mm) D5033-2 Figure 2-2: Installing the Cable on a Transom Mount Transducer 2.3 Selecting the Equipment Location Transducer Mounting Location It is very important that you mount the transducer correctly. The transducer provides the most reliable readings if it looks into water that is smooth and undisturbed. Acoustic noise is always present and these sound waves can interfere with the operation of the transducer. Ambient (background) noise from sources such as waves, fish, rain and other vessels cannot be controlled. Carefully selecting the transducer's mounting location can minimize noise generated by the vessel's propeller(s), shaft(s), machinery, and other echo sounders. The lower the noise level, the higher the echo sounder gain that can be used, and the better the sounder's performance. 30 DSM300 Installation Manual To ensure accurate readings, DO NOT mount the transducer in an area of turbulence or bubbles: · near water intake or discharge openings · behind strakes, fittings or hull irregularities · behind eroding paint (an indication of turbulence) Choose a location where: · The water flowing across the hull is smoothest with a minimum of turbulence and bubbles (especially at high speeds). · The transducer will be continuously covered by water when the boat is moving. If the transducer is mounted near the side of the boat, it may be exposed when the boat is turning. · The transducer beam is unobstructed by the keel or propeller shaft. · There is a minimum deadrise angle. · There is adequate headroom inside the vessel for the height of the thru-hull housing, tightening the nuts, and removing the valve assembly insert. Transom Mount Transducer · Single drive boat ­ Refer to Figure 2-3 . If your boat has one propeller (outboard or inboard), mount the transducer about 18" (455 mm) to the side of the boat's centerline. To reduce any interference caused by air bubbles, choose the side on the downstroke of the propeller (usually the starboard side). · Twin drive boat ­ If your boat has twin propellers (outboard or inboard-outboard), mount the transducer between the drives near the centerline of the boat. If the boat will be operated at high speeds, the transducer may be mounted closer to the centerline of the hull. · If the propeller can be turned to steer the boat, allow at least 2" (50 mm) beyond the swing radius of the propeller. This will prevent the propeller from damaging the transducer when it is turned. Chapter 2: Transducer Installation 31 Approximately 18 in (457 mm) clearance Be sure to allow at least 2 in (50 mm) beyond the swing radius of the propeller D4871-2 Figure 2-3: Transom Mount Transducer Location · Do not mount the transducer behind any hull fittings, intakes or other parts extending from the hull that may cause turbulence or air bubbles. · The bracket has a quick-release mechanism, shown Figure 2-4 . This allows the transducer to flip up if it hits any debris or the bottom. Allow enough clearance above the transducer for it to swing upwards completely ­ this is about 10" (254 mm), measured from the bottom of the transom. Transducer in released position Allow a clearance of at least 254 mm (10 in) D4872-2 Figure 2-4: Transom Mount Transducer - Quick-release Bracket 32 DSM300 Installation Manual · On a boat with a fiberglass hull, the leading edge of the transducer should extend 1/8" (3.2 mm) to 1/4" (6 mm) below the bottom edge of the hull as shown in Figure 2-5 . On an aluminum hull, the transducer should extend a bit more ­ 1/4" (6 mm) to 3/8" (9 mm) · If the boat will be trailered, be sure the transducer will not hit any rollers, bunks or fittings on the trailer. Average transom angle no wedge necessary Vertical transom place wedge this way Sloping transom place wedge this way 2° to 5° 2° to 5° 2° to 5° For fibreglass hull 1/8 to 1/4 in (3.2 to 6 mm) For aluminium hull 1/4 to 3/8 in (6 to 9 mm) No! No! No! D4873-2 The bow of the transducer is above the bottom of the transom, creating cavitation. Rivets on the hull are creating bubbles. Lower the transducer a bit. The rear of the transducer is too high, creating cavitation. Figure 2-5: Transom Mount Transducer - Vertical Position Thru-hull Transducer and In-hull Transducer Similar consideration should be given to the location of thru-hull and in-hull transducers. Figure 2-6 shows the best transducer location for different hull types. · Displacement hull powerboat ­ Locate at 1/3 aft load waterline length (LWL) and 6 - 12" (150-300 mm) off the centerline on the side of the hull where the propeller is moving downward. · Planing hull powerboat ­ Mount well aft, on or near the centerline, and well inboard of the first set of lifting strakes to ensure that it is in contact with the water at high speeds. Mount on the side of the hull where the propeller is moving downward. Chapter 2: Transducer Installation 33 · · · · · Outboard and I/O ­ Mount just forward of the engine(s). Inboard ­ mount well forward of the propeller(s) and shaft(s). Step-hull ­ Mount just ahead of the first step. Boats capable of speeds above 25 kn (29 m.p.h.) ­ Review transducer location and operating results of similar boats before proceeding. Fin keel sailboats ­ Mount to the side of the centerline and forward of the fin keel 1 - 2 ft (300-600 mm). Full keel sailboats ­ Locate amidships and away from the keel at the point of minimum deadrise angle. Fiberglass Hulls ­ Since the hull absorbs acoustic energy, transmitting through the hull reduces the sensor's performance. Fiberglass hulls are often reinforced in places for added strength. These cored areas contain balsa wood or structural foam, which are poor sound conductors. If you cannot avoid locating the sensor over coring, follow the instructions for "Installation in a Cored Fiberglass Hull" on page 55. Thru-hull Transducer Headroom­ Allow adequate headroom inside the vessel for the height of the thru-hull housing, tightening the nuts and removing the insert. The minimum headrooms are: With fairing: 10" (254 mm) Without fairing: 12" (305 mm) In-hull Transducer ­ Find a location where the fiberglass is solid: There are no air bubbles trapped in the fiberglass resin. There is no coring, flotation material, or dead air space sandwiched between the inside skin and the outer skin of the hull. 34 DSM300 Installation Manual Displacement hull Pressure waves 1/3 Aft Load waterline length (LWL) 6 - 12 in (150 -- 300 mm) Planning hulls Outboard and I/O Inboard Full keel sailboat Step hull Fin keel sailboat D4857-2 Figure 2-6: Best Location for Thru Hull Transducer Chapter 2: Transducer Installation 35 2.4 Installing the Transom Mount Transducer Preparation Transducer Mounting Bracket When installed, the lower surface of the transducer should tilt down toward the rear at a slight angle (2° to 5°). The mounting bracket includes a wedge; depending on the angle of the transom on your boat, you may need to install this wedge to get the correct transducer angle. 1. To attach the transducer to the bracket, insert the transducer mounting lugs into the slot in the bracket as shown in Figure 2-7 . Correct Attach the two parts Incorrect Bracket is installed upside down Lower the transducer and snap in the release clip D4874-2 Figure 2-7: Fitting the Transducer to the Bracket 2. Looking at the rear of the boat, be sure the bracket is vertical (perpendicular to the water line) and hold the bracket (plus the wedge, if used) against the transom. Trace the position of the screw slots, then mark the screw positions as shown in Figure 2-8 . The outer two screws should be placed about 1/4" (6 mm) up from the bottom of each slot, the center screw should be placed about 1/4" (6 mm) down from the top. This will allow the bracket to be adjusted up or down. Remove the bracket. 36 DSM300 Installation Manual Correct alignment Insert screws 1 and 3, 6.4 mm (1/4 in) from the bottom of the slots, and screw 2, 6.4 mm (1/4 in) from the top the slot to allow room for adjustment. 1 2 3 Incorrect alignment If screws are inserted this way it won't be possible to make the height adjustment. 1 2 3 D4875-2 Figure 2-8: Position of Screws in Mounting Bracket Installation 1. On a fiberglass hull, to minimize surface cracking of the gel coat: Before drilling the pilot holes, use a 1/4" (6 mm) drill bit to drill a shallow hole (chamfer) at each location about 1/16" (1.5 mm) deep. Drill pilot holes 3/4" (19 mm) deep using a 9/64" (3.6 mm) drill bit. To prevent drilling too deeply, wrap masking tape around the drill bit about 7/8" (22 mm) from the tip. Drill in only as far as the tape. 2. Apply a good quality marine sealant to the pilot holes to protect the hull from water penetration. 3. Attach the bracket to the hull using the panhead screws with flat washers. Do not completely tighten the screws yet. 4. Move the bracket up or down so the leading edge of the transducer has the clearance shown in Figure 2-5 . 5. Once the bracket is in the correct position tighten the screws. 2.5 Installing the Thru-hull Transducer Tools and Material Needed Water-based antifouling paint (mandatory for boats kept in salt water) Safety goggles Dust mask Electric drill Drill bit: 1/8" (3 mm) Chapter 2: Transducer Installation 37 Hole saw: Fiberglass or wood Drill 2" (51 mm) Aluminium or steel hull Drill 2-1/8" (54 mm) Sandpaper File (for installation in a metal hull) Mild household detergent or weak solvent (alcohol) Marine sealant Slip-joint pliers Silicone grease or petroleum jelly Tie-wraps Cored fiberglass hull installation: Hole saw for hull interior 2-3/8" (60 mm) Cylinder, wax, tape and casting epoxy Fairing; Level and protractor (installation with a fairing) Rasp (installation with a fairing) Preparation Fairing Most vessels have a deadrise angle at the transducer's mounting location. If the transducer is mounted directly to the hull, the sonar beam will be tilted off-vertical at the same angle as the deadrise. To offset this deadrise angle, you can install a transducer fairing. Different fairings are available to fit various transducers. CAUTION: Using a Fairing If thru-hull transducers are not carefully installed and fitted to the shape of the hull, the vessel may take on water. To ensure proper alignment and a secure fit, these transducer models MUST be installed with a fairing. In addition to improving sounder performance at all speeds, the fairing allows better fitting to the hull and dramatically increases the sealing surface. Fairings are also strongly recommended for use with other high performance transducers. See the table that follows. The fairing is used to: · Vertically orient the sound beam by mounting the transducer parallel to the water surface · Minimize aerated water flowing over the transducer's face by mounting it in deeper water · Reduce drag by directing the water around the multisensor 38 DSM300 Installation Manual The fairing is made of high impact urethane with an integrated cutting guide. It can be shaped to accommodate a deadrise angle of up to 25° and a range of hull thicknesses as follows: Fairing No. E66023 E66023 E66025 E66034 Used with Transducer No. (model) E66056 (B744V) E66057 (B744VL) E66024 (B256) E66033 (B260) Max.

After cutting the fairing, use the remaining section with the cutting guide as the backing block (see Figure 2-10 ). Chapter 2: Transducer Installation 39 BO W Cutting guide Triangular recess for anti-rotation bolt D5567-1 Figure 2-10: Transducer Fairing Cutting the Fairing 1. Measure the deadrise angle of the hull at the selected location using a digital level, or bubble level and protractor (see Figure 2-9 ). 2. Tilt the band saw table to the measured angle and secure the cutting fence (see Figure 2-11 ). Band saw table Cutting guide Deadrise angle Fence Bow end for installation on port side D4860-2 Figure 2-11: Cutting the Fairing 40 DSM300 Installation Manual CAUTION: The arrow on the fairing always points forward towards the bow. Be sure to orient the fairing on the band saw so the angle cut matches the intended side of the hull. 3. Place the fairing on the table so the cutting guide rests against the fence. The arrow/blunt end will point toward you for installation on the port side and away from you for installation on the starboard side of the boat. CAUTION: Always wear safety goggles and a dust mask when drilling. 4. Recheck steps 1 through 3, then cut the fairing. 5. Shape the fairing to the hull as precisely as possible with a rasp or power tool. Antifouling Paint Marine growth can accumulate rapidly on the transducer's surface, reducing performance in weeks. Surfaces exposed to salt water must be coated with antifouling paint. Use water-based antifouling paint only. Never use ketone-based paint since ketones can attack many plastics, possibly damaging the transducer. Reapply paint every six months or at the beginning of each boating season. It is easier to apply antifouling paint before installation, but allow sufficient drying time. As illustrated in Figure 2-12 , paint the following surfaces: Exposed area of the housing, including the acoustic window Bore of the housing up to 1-1/4" (30 mm) Outside wall below lower O-ring Exposed end of the paddle wheel insert Paddle wheel cavity Paddle wheel Blanking plug below the lower O-ring and the exposed end Chapter 2: Transducer Installation 41 Housing Paddlewheel insert Lower 'O' ring Paint exposed housing and bore up to 1.1/4" (30 mm) Paint outside wall below the lower 'O' ring including exposed end, paddlewheel cavity and paddlewheel D4859-2 Figure 2-12: Applying Antifouling Paint Installation Note: To install the thru-hull transducer in a cored fiberglass hull, follow the instructions in Installation in a Cored Fiberglass Hull on page 48. Drilling Holes CAUTION: Always wear safety goggles and a dust mask when drilling. 1. Drill a 1/8" (3 mm) pilot hole perpendicular to the water line from inside the hull (see Figure 2-9 ). If there is a rib or strut near the mounting location, drill from the outside. If the pilot hole is drilled in the wrong location, drill a second hole in a better location. Apply masking tape to the outside of the hull over the incorrect hole and fill it with epoxy. 42 DSM300 Installation Manual 2. Cut a hole from outside the hull: Fiberglass or wood hull ­ Use a 2" (51 mm) hole saw. Aluminium or steel hull ­ Use a 2-1/8" (54 mm) hole saw to accommodate the isolation sleeve used to prevent contact between the stainless steel housing and the metal hull. 3. Sand and clean the area around the hole, inside and outside, to ensure that the sealant will adhere properly to the hull. If there is any petroleum residue inside the hull, remove it with either a mild household detergent or a weak solvent (alcohol) before sanding. 4. Remove one safety ring, the retaining pin, the cap nut, and the hull nut from the transducer (see Figure 2-13 ). Retaining pin Safety ring Cap nut Stem Hull nut Backing block Hull Marine Fairing sealant D5566-1 Figure 2-13: Seating Dry Fit for Fairing CAUTION: If a fairing is used, the anti-rotation bolt must be installed to prevent the fairing from rotating when the boat is underway. 1. Dry fit the transducer to locate the hole for the anti-rotation bolt. 2. Thread the transducer cable through the large hole in the fairing and through the mounting hole in the hull. Seat the transducer firmly in the recess in the fairing. Note: The transducer must be flush with the fairing. If it is recessed more than 1/64" (0.5mm) inside the fairing, you may carefully file or sand the fairing flush with the transducer. Chapter 2: Transducer Installation 43
