• If you are routing the cable using a pass-through hole, push it through the hole you drilled in step 12, and install the cable-entry cover (Installing the Cable-Entry Cover, page 2). • If you are not routing the cable using a pass-through hole, route the cable up and over the top of the transom . Ä You should avoid routing the cable close to electrical wires or other sources of electrical interference. Installing the Cable-Entry Cover If you routed the cable through the transom after you installed the transducer, you should install the cable-entry cover to keep water from entering your boat. 1 Place the cable-entry cover over the hole and the cable, À with the opening pointing downward, and mark the location of the two pilot holes. 2 Align the transducer parallel to the water line , and mark the Á center location of the two outer holes of the transducer mount. 3 Wrap a piece (7/10 in.) from of tape around the point of the a 4 bit, mm (5/32 in.) bit to avoid drilling at 18 mm the pilot holes too deep. 4 If you are installing the bracket on fiberglass, place a piece of tape over the pilot-hole location to reduce cracking of the gel coat. 5 Using the 4 18 mm (7/10 mm in.) (5/32 in.) bit, drill the deep at the marked pilot holes locations. approximately 6 Apply marine sealant to the included 20 mm screws, and attach the transducer assembly to the transom. 7 Route the cable under the transom mount wire hook. 2 Remove the cable-entry cover, and, using a bit, drill the pilot holes approximately 10 mm 3.2 (3/8 mm in.) (1/8 in.) deep. 3 Fill the pass-through hole with marine sealant so it covers the cable completely and there is excess sealant around the hole and the cable. 4 Place the cable-entry cover over the hole and the cable, with the opening pointing downward. 5 Apply marine sealant to the included 12 mm M4 screws, and attach the cable-entry cover to the transom. 6 Wipe away all excess marine sealant. Installing the Transducer on a Trolling Motor NOTICE Do not cut the transducer cable. Cutting the transducer cable will void your warranty. 1 Insert the hose clamp through the slot on the transducer À mount , until equal lengths extend on both sides of the Á mount. 8 If you must route the cable through the transom, choose a pilot-hole location well above the waterline and mark it. Â 9 Place a cable clamp on the transducer cable , Ã approximately halfway between the transducer and the top of the transom or the pilot hole. 10Mark the pilot-hole location for the cable clamp, and using a 3.2 (3/8 mm (1/8 in.) in.) deep. bit, drill a pilot hole approximately 10 mm 11Apply marine sealant to the included 12 mm screw, and attach the cable clamp to the transom. 12If you marked a pilot hole in step 8, choose the appropriate drill bit and drill a pass-through hole completely through the transom: • If you have the 4-pin cable, use a 16 mm (5/8 in.) drill bit. • If you have the 8-pin cable or the 12-pin cable, use a 25 mm (1 in.) drill bit. 13Route the transducer cable to the sounder: 2 Place the transducer mount against the body of the trolling motor with the narrow end of the transducer pointed away from the propeller. 3 Secure the hose clamp around the body of the trolling motor, and tighten the hose clamp. 2
