531196-2_A HUMMINBIRD INSTALLATION GUIDE There are three basic installation tasks that you must perform for the Humminbird Fishing System: · Installing the Humminbird control head · Installing the transducer · Testing the complete installation and locking the transducer position. The transducer can either be installed inside the hull, on the transom of the boat, or onto a trolling motor, depending on your transducer type. There are also two different types of transducer mounting brackets, the Single Piece and the Two Piece Kick-up. In addition, if you have purchased a Plus model, you may want to install the included Temperature/Speed accessory, using the separate installation instructions included with the accessory. NOTE: If the included transducer will not work for your application, you may exchange it, NEW and UNASSEMBLED, with mounting hardware included, for a transducer appropriate for your application - often at very little or no charge depending on the transducer. Call the Humminbird Customer Resource Center (334-687-0503) for details and pricing, or visit www.humminbird.com, Product Support/Transducer Exchange for more information. NOTE: Due to the wide variety of hulls, only general instructions are presented in this installation guide. Each boat hull represents a unique set of requirements that should be evaluated prior to installation. In addition to the parts supplied, you will need a hand drill with various bits, a socket (/") wrench, a Phillips head screwdriver, and marine-grade silicone sealant. NOTE: Please read all instructions carefully and completely before beginning the installation process. NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating. CONTROL HEAD INSTALLATION 1. Determine Where to Mount Begin the installation by determining where to mount the control head. Consider the following to determine the best location: · To check the location planned for the control head, test run the cables for power, transducer and Temp/Speed accessory (if applicable). See the installation section for your transducer type in order to plan the location of the transducer. · There are two ways to route the cables to the unit: through a hole in the mounting surface underneath the mounting bracket, or from a hole outside the mounting bracket. Routing the cables under the mounting bracket provides maximum weather protection; this may not be feasible, however, if the area under the control head is inaccessible. In this case, route the cables through a hole at another location and cover with the supplied hole cover. · The mounting surface should be stable enough to protect the control head from excessive wave shock and vibration, and should provide visibility while in operation. · The mounting area should allow sufficient room for the unit to pivot and swivel freely, and for easy removal and installation (Figures 1 and 2). Figure 1 Figure 2 2. Connect the Power Cable to the Boat CAUTION: Some boats have 24 or 36 Volt electric systems, but the control head MUST be connected to a 12 VDC power supply. GROUND POSITIVE A 6' (2 m) long power cable is included to supply power to the control head. You may shorten or lengthen the cable using 18 gauge multi-stranded copper wire. The control head power cable can be connected to the electrical system of the boat at two places: a fuse panel usually located near the console, or directly to the battery. NOTE: Make sure that the power cable is not connected to the control head at the beginning of this procedure. Figure 3 1a. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that match the terminal on the fuse panel. Attach the black wire to ground (-), and the red wire to positive (+) 12 VDC power (Figure 3). 1b. If you need to wire the control head directly to a battery, obtain and install an inline fuse holder and a 1 to 3 amp fuse (not included) for the protection of the unit (Figure 4). Humminbird is not responsible for over-voltage or over-current failures. NOTE: In order to minimize the potential for interference with other marine electronics, a separate power source (such as a second battery) may be necessary. Inline Fuse Holder Figure 4 3. Drill the Mounting Bracket Mounting Holes 1. Set the control head mounting bracket in place on the mounting surface. Mark the four mounting screw locations with a pencil or punch. 2. Set the mounting bracket aside, and drill the four mounting screw holes using a /" (3.5 mm) bit. 1" (25 mm) Hole Location Mounting Hole Locations Figure 5 4. Route the Cables Through the Mounting Bracket 1a. If the cables must pass through a hole directly beneath the mounting bracket, mark and drill an additional 1" (25 mm) hole centered between the four mounting holes (Figure 5). Route the cables through the grommet, then press the grommet in place around the cables and into the 1"(25 mm) hole. Pass the cables out of the top of the mounting bracket (Figure 6). 1b. If the cables cannot be routed directly beneath the mounting bracket, mark and drill a 1" (25 mm) hole that will allow you to run the cables close to the bracket. Pass the cables through the 1" (25 mm) hole, through the mounting base, and out of the top of the mounting bracket (Figure 7). Using needle-nose pliers, break out the tabs on the rear of the mounting base (Figure 8). Place the Hole Cover over the mounting surface hole, then use it to mark the position of the two mounting screws. Remove the Hole Cover, drill the two mounting holes using a /" (3.5 mm) bit, fill them with marine-grade silicone, then replace the Hole Cover and insert the #8 Phillips countersink wood screws. Hand-tighten only. 2. Place the mounting bracket on the mounting surface aligned with the drilled holes and fill the mounting holes with marine grade silicone. Insert the four #8 Phillips countersink wood screws into the mounting holes. Hand-tighten only. Cables Mounting Bracket Grommet Figure 6 Hole Cover Figure 7 5. Assembling the Connector Holder 1. Insert both the power and the transducer cable plugs into the connector holder. The cable plugs are labeled, and there are corresponding labels on the connector holder (Figure 9). The slots for the plugs are keyed to prevent reverse installation, and insertion should be easy - do not force plugs. Break-out tabs 2. Carefully pull the excess cable from beneath the mounting surface so that the connector holder aligns with the mounting holes on the front of the mounting bracket (Figure 10). 3. Snap the support plate onto the rear of the connector holder (Figure 11). 4. Insert the connector holder into place and fasten it to the mounting bracket using the two #6-32 x ³/" (19 mm) screws (Figure 12). Hand-tighten only. 5. Slide the control head onto the mounting bracket until it is fully seated. To remove the unit, grasp the unit with both hands, then firmly press the latch on the rear of the unit and lift (Figure 13). Figure 8 Connector Holder Transducer Communications Accessory Power Figure 9 NOTE: This latch is heavy-duty to withstand marine use, and significant force must be applied. You are now ready to install the transducer. Find the section that refers to your transducer type. Connector Holder Cable Connector Figure 10 TRANSOM TRANSDUCER INSTALLATION Support Plate 1. Determine Transducer Mounting Location NOTE: If transom mounting is not possible because of a stepped hull or cavitation noise, and you have a single layer fiberglass hull, In-hull installation is an option. See Inside the Hull Transducer Installation for more information. Figure 11 First, determine the best location on the transom to install the transducer. Consider the following to find the best location: · It is very important to locate the transducer in an area which is relatively free of turbulent water. As a boat moves through the water, turbulence is generated by the weight of the boat, and the thrust of the propeller(s) - either clockwise or counter-clockwise. This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s) (Figure 14). Clockwise propellers create more turbulence on the port side. On outboard or inboard/outboard boats, it is best to locate the transducer at least 15" (380 mm) to the side of the propeller(s). · The best way to locate turbulence-free water is to view the transom while the boat is moving. This method is recommended if maximum high-speed operation is a high priority. If this is not possible, select a location on the transom where the hull forward of this location is smooth, flat and free of protrusions or ribs. · The hydrodynamic shape of your transducer allows it to point straight down without deadrise adjustment (Figure 15). · On boats with stepped hulls, it may be possible to mount the transducer on the step. Do not mount the transducer on the transom behind a step to avoid popping the transducer out of the water at higher speeds; the transducer must remain in the water for the control head to maintain the sonar signal (Figure 16). · If the transom is behind the propeller(s), it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered (see Inside the Hull Transducer Installation).

Mounting the Bracket 1. Remove the transducer mounting template from this sheet. NOTE: Please make sure that you use the correct drill holes for the hull composition of your boat. Step PLACE EITHER CORNER ON DEADRISE ANGLE Figure 15 2. Hold the template on the transom of the boat in the location where the transducer will be installed (Figure 15). Align the template vertically, matching the lower edge of the transom with the bottom corner of the template. If your propeller moves clockwise as the boat moves forward, mount the transducer on the starboard side, and use the bottom left corner of the template. If your propeller moves counter-clockwise as the boat moves forward, mount the transducer on the port side, and use the bottom right corner of the template. 3. Using a pencil or punch, mark the two mounting holes (shown on the template for your type of hull) on the transom. Do not mark or drill any other holes at this time. 4. Using a /" (3.5 mm) bit, drill the two holes to a depth of approximately 1" (25 mm). Figure 16 Toothed Lock Washer Pivot Knuckle Nyloc Nut Pivot Bolt Transducer Arms Figure 17 3. Assemble the Transducer NOTE: The transducer assembly referred to in this step consists of the transducer connected to either the Single Piece or the Two Piece Kick-up mounting bracket. Toothed Lock Washer Kick-up Pivot Knuckle Transducer Arms Pivot Bolt Nyloc Nut 1. Attach the Single Piece mounting bracket (Figure 17) or the Two Piece Kick-up pivot (Figure 18) to the transducer body, using the ¹/"- 20 x 1¹/" Phillips head pivot bolt, the nyloc nut, and the two toothed lock washers. NOTE: The toothed lock washers must be positioned between the transducer arms and the pivot knuckle regardless of mounting bracket type (Figure 19). Figure 18 Toothed Lock Washer 2. Using a Phillips screwdriver and a /" wrench, loosely tighten the pivot bolt (Figures 17, 18). Do not completely tighten the assembly at this time, so the pivot angle can be adjusted later. 3. Only if you have a Kick-up transducer mounting assembly, insert the pivot/transducer assembly into the mounting bracket (see Figure 20). 4. Do not snap the assembly closed. Figure 19 4. Mount the Transducer Assembly to the Transom 1. Apply marine-grade silicone sealant to the mounting holes drilled into the transom. Figure 20 Initial Bracket Mounting 2. Align the transducer assembly with the drilled holes in the transom (Figure 21). 3. Using the appropriate tool for your mounting hardware, attach the transducer assembly to the boat transom as shown , using #8 x /" (16 mm) wood screws. Do not fully tighten the mounting screws in order to vertically adjust the transducer. If you have a Two Piece Kick-up transducer mounting assembly, snap the pivot down into place. 5. Adjust the Running Position of the Transducer The transducer mounting bracket allows height and tilt adjustment, while the pivot bolt allows angular adjustment. These adjustments will help reduce cavitation (Figures 23 and 24). Initially, adjust the transducer as described in the following paragraphs. Further adjustment may be necessary to refine the installation after high-speed testing. 1. First, adjust the pivot angle of the transducer body, so its length is parallel with the l ...
