2 Seat the transducer housing firmly within the fairing block recess. 3 Apply marine sealant to the face of the fairing block that must contact the hull. 4 Apply marine sealant to the face of the backing block that must contact the inner hull. 5 From outside the hull, insert the transducer cable and transducer stem through the mounting hole. 6 From inside the hull, slide the backing block onto the transducer stem and seat it firmly against the inner hull. The fairing and transducer must be parallel to the keel. 7 From inside the hull, apply the included anti-seize compound to the exposed transducer stem and anti-rotation bolt. 8 From inside the hull, use slip-joint pliers or a crescent wrench to secure the backing block to the transducer stem with the included 46 mm hull nut , nylon washer , and rubber washer . Do not over-tighten the hull nut. 9 From inside the hull, use slip-joint pliers or a crescent wrench to secure the backing block to the anti-rotation bolt with the included M8 nut and 8 mm washer . Do not over-tighten the M8 nut. 10Before the sealant hardens, remove all excess sealant on the outside of the fairing block and exterior hull to ensure smooth water flow over the transducer. Non-cored/Fiberglass/Wooden Boat Hull Installation Instructions Thru-Hull Transducer in a Non-cored/Fiberglass Hull with a Fairing Block If the deadrise angle of your mounting location exceeds 5°, you should use a fairing block to mount the device. Drilling the Transducer Stem Hole and the Anti-Rotation Bolt Hole in a Non-Cored or Fiberglass Hull Before you can drill holes for the anti-rotation bolts, you must drill the hole for the transducer stem, and you must cut the fairing block (Cutting the Fairing Block, page 2). You should follow these instructions when you are using a fairing block to mount the transducer on a boat that does not have a cored fiberglass hull. 1 Select a mounting location without surface irregularities or obstructions. 2 Using the template, mark the location of the stem hole and anti-rotation bolt. 3 Drill a 3 mm (1/8 in.) pilot hole through the hull at the stem hole location, from outside the hull. The hole must be perpendicular to the water surface. 4 If the vessel has a fiberglass hull, place masking tape over the pilot hole and surrounding area outside the hull to prevent damage to the fiberglass. 5 If you taped over the pilot hole, use a utility knife to cut out the hole in the tape. 6 While holding a 32 mm (1 1/4 in.) spade bit plumb, cut a hole from outside the hull at the stem hole location. The hole must be perpendicular to the water surface. 7 Sand and clean the area around the hole. 8 While holding a drill with a 9 mm (3/8 in.) bit plumb, drill the anti-rotation bolt hole through the hull. The holes must be perpendicular to the water surface. 9 Sand and clean the area around the holes with a solvent wash to remove dust particles. Applying Marine Sealant to a Thru-Hull Transducer You must apply marine sealant to the transducer to ensure a tight, waterproof seal between the fairing block and the hull. Do not apply sealant directly to the stem or anti-rotation bolt. Apply marine sealant around the base of the stem and anti-rotation bolt on the transducer. 4
