Caution: Never mount a bronze housing in a metal hull, because electrolytic corrosion will occur. · Stainless steel housing compatible with all hull materials. · Aluminum or steel hull--Use a stainless steel housing/stem to prevent electrolytic corrosion. Caution: Installation requires using a fairing kit to isolate the stainless steel transducer from a metal hull. · Caution: Never install a metal housing on a vessel with a positive ground system. Identify Your Model The model name is printed on the cable tag. About Fairings Nearly all vessels have some deadrise angle at the mounting location. If the transducer is mounted directly to the hull, the sound beam will be tilted off the vertical at the same angle as the deadrise. A fairing is strongly recommended if the deadrise angle exceeds 10°. · Orients the sound beam straight down by mounting the transducer parallel to the water surface · Minimizes aerated water flowing over the transducer's face by mounting it deeper in the water Tools & Materials Safety goggles Dust mask Electric drill Drill bits: Pilot hole 3mm or 1/8" B45, B46, SS505 22mm or 7/8" B240, B260, B261, SS560 33mm or 1-5/16" B256 30mm or 1-3/16" Sandpaper Mild household detergent or weak solvent (alcohol) File (installation in a metal hull) Fairing (mandatory for SS505 and SS560) Digital level or bubble level & protractor (installation w/ fairing) Band saw or hand saw (installation with a fairing) Rasp or power tool (installation with a fairing) Marine sealant Slip-joint pliers Zip-ties Water-based antifouling paint (mandatory in salt water) Installation in a cored fiberglass hull: (see page 4) Drill bit for hull interior: B45, B46, SS505 35mm or 1-3/8" B240, B260, B261, SS560 42mm or 1-5/8" B256 40mm, 41mm, or 1-5/8" Cylinder, wax, tape, and casting epoxy Airmar Polymer Fairing Made of a high-impact polymer with an integrated cutting guide, an Airmar fairing is safer and easier to cut with a band saw and shape with hand tools than custom fairings. It can be shaped to accommodate a deadrise angle of up to about 25°. (For fairing part numbers, see "Replacement Parts" on page 4.) A backing block is mounted inside the hull to provide a level surface for the hull nut to seat against (see Figure 2). It is fabricated matching the interior deadrise angle of the boat. After cutting an Airmar fairing, use the remaining section with the cutting guide for the backing block. Airmar High-Performance Fairing A high-performance fairing has a long streamlined shape for excellent performance above 15 kn (18MPH) (see "Parts" on page 4). Mounting Location Acoustic Noise Acoustic noise is always present and these sound waves can interfere with the operation of the transducer. Background noise from sources such as: waves, fish, and other vessels cannot be controlled. However, carefully selecting the transducer mounting location can minimize the effect of vessel generated noise from the propeller(s) and shaft(s), other machinery, and other echosounders. The lower the noise level, the higher the echosounder gain setting that can be used. AIRMAR pressure waves ® · Fin keel sailboat--Mount to the side of the centerline and forward of the fin keel 300­600mm (1­2'). · Full keel sailboat--Locate amidships and away from the keel at the point of minimum deadrise angle. 1/3 aft LWL (Load Waterline Length) displacement hull 150-300mm (6-12") Installation--No fairing or standard fairing only WARNING: High-performance fairing must be installed following the Installation Instruction Supplement that comes with the fairing. The high-performance fairing requires an anti-rotation bolt. Failure to install the anti-rotation bolt may result in the fairing rotating while the boat is underway. The effect may be violent movement and loss of steering. This could result in serious injury or death to passengers and/or damage to the boat or other property. Metal hull--The SS505 and SS560 must be isolated from a metal hull. For your safety you must follow the Installation Instruction Supplement provided with the fairing. outboard and I/O planing hulls inboard step-hull Cored fiberglass hull--Follow separate instructions on page 4. fin keel sailboat No fairing--If you are installing a transducer without a fairing, disregard all references to a fairing. Hole Drilling full keel sailboat Warning: Always wear safety goggles and a dust mask. 1. Drill a 3mm or 1/8" pilot hole perpendicular to the waterline from inside the hull (see Figure 2). If there is a rib, strut or other hull irregularity near the selected mounting location, drill from the outside. 2. Using the appropriate drill bit, cut a hole from outside the hull. Be sure to hold the drill plumb, so the hole will be perpendicular to the water surface. 3. Sand and clean the area around the hole, inside and outside, to ensure that the marine 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. Metal hull--Remove all burrs with a file and sandpaper. AIRMAR Figure 1. Best location for the transducer Placement Choose a location where: · The water flowing across the hull is smoothest with a minimum of bubbles and turbulence (especially at high speeds). · The transducer will be continuously immersed in water. · There is a minimum deadrise angle. · The transducer beam is unobstructed by keel or propeller shaft(s). · There is adequate headroom inside the vessel for the height of the housing and tightening the nut. Caution: Do not mount the transducer: Near water intake or discharge openings Behind strakes, fittings, or hull irregularities Behind eroding paint (an indication of turbulence) cable stem ® Aft View Boat Types (see Figure 1) · Displacement hull powerboat--Locate 1/3 aft LWL and 150­300mm (6­12") off the centerline on the side of the hull where the propeller is moving downward. · Planing hull powerboat--Mount well aft, near the centerline, and well inboard of the first set of lifting strakes to insure that the transducer is in contact with the water at high speeds. Mount on the side of the hull where the propeller is moving downward. Outboard and I/O--Mount just forward and to the side of the engine(s). Inboard--Mount well ahead of the propeller(s) and shaft(s). Step-hull--Mount just ahead of the first step. Boat capable of speeds above 25kn (29MPH)--Review transducer location and operating results of similar boats before proceeding. 2 hull nut hull backing block slope of hull fairing thickness 6­12mm (1/4­1/2") deadrise angle parallel to waterline standard fairing marine sealant Figure 2.

Apply a 2mm (1/16") thick layer of marine sealant to the surface of the backing block that will contact the hull deadrise angle fence arrow end for installation on port side Installing 1. From outside the hull, thread the cable through the mounting hole. 2. With the fairing in place (if used) and the arrow pointing forward toward the bow, push the stem of the transducer through the mounting hole (see Figure 4). (A symmetrical fairing can be oriented either way.) Take care to align the assembly parallel to the centerline of the boat. Squeeze out any excess sealant. 3. From inside the hull, slide the backing block (if used) and hull nut onto the cable. Seat the backing block against the hull. Screw the hull nut in place and tighten it with slip-joint pliers (see Figure 2 or 5). Wood hull--Allow for the wood to swell. 4. Remove any excess marine sealant on the outside of the hull and fairing to ensure smooth water flow over the transducer. Figure 3. Cutting the standard fairing Cutting the Fairing High-performance fairing--For your safety it is mandatory to follow the Installation Instruction Supplement that comes with 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) 2. Tilt the band saw table to the measured angle and secure the cutting fence (see Figure 3). 3. Place the fairing on the table so the cutting guide rests against the fence. The arrow will be pointing toward you for installation on the port side and away from you for installation on the starboard side of the boat (see Figures 3 and 4). Caution: The ARROW always points forward toward the bow. (A symmetrical fairing can be oriented either way.) Be sure to orient the fairing on the band saw so the angle cut matches the intended side of the hull and not the mirror image. 4. Adjust the cutting fence. The fairing must be between 6­12mm (1/4­1/2") at its thinnest dimension (see Figure 2). Warning: Always wear safety goggles and a dust mask. 5. Recheck steps 1 through 4; then cut the fairing. 6. Shape the fairing to the hull as precisely as possible with a rasp or power tool. 7. Use the remaining section of the fairing for the backing block. Caution: If the transducer came with a connector, do not remove it to ease cable routing. If the cable must be cut and spliced, use Airmar's splash-proof Junction Box 33-035 and follow the instructions provided. Cutting the cable or removing the connector, except when using Airmar's junction box, will void the warranty. 5. Route the cable to the instrument being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the transducer cable from other electrical wiring and the engine. Coil any excess cable and secure it in place with zip-ties to prevent damage. 6. Refer to the instrument owner's manual to connect the transducer to the instrument. AIRMAR stem hull nut backing block hull ® BOW Bedding Caution: Never pull, carry, or hold the transducer by the cable as this may sever internal connections. 1. Remove the hull nut (see Figure 2 or 5). 2. Thread the transducer cable through the fairing (if used). 3. Apply a 2mm (1/16") thick layer of marine sealant around the sides of the housing that will contact the fairing (or hull if no fairing is used). Apply a 2mm (1/16") thick layer of marine sealant to the stem of the housing. The sealant must extend 6mm (1/4") higher than the combined thickness of the fairing, hull, backing block, and hull nut. This will ensure there is marine sealant in the threads to seal the hull and hold the hull nut securely in place.

Transducer and fairing orientation (blunt end toward bow) 3 Checking for Leaks Warning: Never install a thru-hull transducer and leave the boat in the water unchecked for several days. When the boat is placed in the water, immediately check around the thru-hull transducer for leaks. Note that very small leaks may not be readily observed. It is best not to leave the boat in the water for more than 3 hours before checking it again. If there is a small leak, there may be considerable bilge water accumulation after 24 hours. If a leak is observed, repeat "Bedding" and "Installing" on page 3 immediately. Caution: Completely seal the hull to prevent water seepage into the core. 5. Coat a hollow or solid cylinder of the correct diameter with wax and tape it in place. Fill the gap between the cylinder and hull with casting epoxy. After the epoxy has set, remove the cylinder. 6. 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 mild household detergent or a weak solvent (alcohol) before sanding. 7. Proceed with "Bedding" and "Installing" on page 3. Installation in a Cored Fiberglass Hull The core (wood or foam) must be cut and sealed carefully. The core must be protected from water seepage, and the hull must be reinforced to prevent it from crushing under the hull nut allowing the housing to become loose. Antifouling Paint Surfaces exposed to salt water must be coated with antifouling paint (see Figure 7). Use water-based antifouling paint only. Never use ketone-based paint since ketones can attack many plastics possibly damaging the transducer. Reapply antifouling paint every 6 months or at the beginning of each boating season. AIRMAR ® Warning: Always wear safety goggles and a dust mask. 1. Drill a 3mm or 1/8" pilot hole perpendicular to the waterline from inside the hull (see Figure 6). If there is a rib, strut, or other hull irregularity near the selected mounting location, drill from the outside. (If the 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.) 2. Using the appropriate size drill bit, cut a hole from outside the hull through the outer skin only. Be sure to hold the drill plumb, so the hole will be perpendicular to the water surface. 3. The optimal interior hole diameter is affected by the hull's thickness and deadrise angle. It must be large enough in diameter to allow the core to be completely sealed. Using the appropriate size drill bit for the hull interior, cut through the inner skin and most of the core from inside the hull keeping the drill perpendicular to the hull. The core material can be very soft. Apply only light pressure to the drill bit after cutting through the inner skin to avoid accidentally cutting the outer skin. 4. Remove the plug of core material so the inside of the outer skin and the inner core of the hull is fully exposed. Sand and clean the inner skin, core, and the outer skin around the hole. AIRMAR dimension equal to the thickness of the hull's outer skin to ensure adequate clearance pour in casting epoxy inner skin antifouling paint Figure 7. SS505 shown Maintenance & Replacement Cleaning Aquatic growth can accumulate rapidly on the transducer's surface reducing its performance within weeks. Clean the surface with a soft cloth and mild household detergent. If the fouling is severe, use a stiff brush or putty knife to remove the growth taking care to avoid making scratches. Wet sanding is permissible with fine grade wet/dry paper. Replacement Parts Lost, broken, and worn parts should be replaced immediately and can be obtained through your marine dealer or instrument manufacturer.
