2 Apply marine sealant to the bushings, and at the base of the anti-rotation bolt and transducer stem. 3 Seat the transducer housing firmly within the fairing block recess. 4 Apply marine sealant to the side of the fairing block that must contact the hull. 5 Apply marine sealant to the side of the backing block that must contact the hull. 6 From outside the hull, insert the transducer cable and transducer housing through the mounting hole. 7 From inside the hull, slide the backing block onto the transducer and seat it firmly against the hull. 8 Apply the included anti-seize compound to the exposed transducer stem and anti-rotation bolt. 9 From inside the hull, use slip-joint pliers to secure the backing block to the transducer stem with the included 46 mm hull nut , the nylon washer , and the rubber washer . 10From inside the hull, use slip-joint pliers to secure the backing block to the anti-rotation bolts with the included M8 nut and 8 mm washer . 11Before 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. Thru-Hull Transducer in a Metal Hull without a Fairing Block If the deadrise angle of your mounting location does not exceed 5 degrees, you can mount the device without a fairing block. Drilling the Transducer Stem and Anti-Rotation Bolt Holes You should follow these instructions if you are mounting your transducer on a metal hull boat and you are not using a fairing block. 1 Trim the included transducer template. 2 Select a mounting location without surface irregularities or obstructions. 3 Using the template, mark the location of the stem hole and anti-rotation bolt. 4 Drill a 3 mm (1/8 in.) pilot hole through the hull at the stem hole location, from outside the hull. 5 Using a 38 mm (1 1/2 in.) hole saw, cut the stem hole from outside the hull. The hole must be perpendicular to the water surface. 6 While holding a drill with a 12 mm (1/2 in.) bit plumb, drill the anti-rotation bolt hole from outside the hull. The holes must be perpendicular to the water surface. 7 Remove the template from the mounting location. 8 Sand and clean the area around the holes with a solvent wash to remove dust particles. Installing the Transducer in a Metal Hull without a Fairing Block It is recommended that two installers complete these instructions, with one positioned outside the boat and one inside the boat. NOTE: When installing a transducer in an aluminum or steel hull, you must use the included isolation plate. 1 Secure the bushings to the anti-rotation bolt and transducer stem . 2 Seat the isolation plate firmly against the transducer. 3 Apply marine sealant to the base of the transducer stem and anti-rotation bolt, and the side of the isolation plate that must contact the hull. NOTE: Apply enough marine sealant on all surfaces to ensure bonding between the plate and the hull, including a tight perimeter seal. 4 From outside the hull, insert the transducer through the mounting hole and seat it firmly against the hull. 5 From inside the hull, apply the included anti-seize compound to the exposed transducer stem and anti-rotation bolts. 6 From inside the hull, use slip-joint pliers or a crescent wrench to secure the included 46 mm hull nut , nylon washer , and rubber washer to the transducer stem. 7 From inside the hull, use slip-joint pliers to secure the included M8 nut and 8 mm nylon washer to the antirotation bolt. 7
