[. . . ] Remove one safety ring, the retaining pin, the cap nut, and the hull nut from the transducer (see Figure 2-7 ). Chapter 2: Installation 23 Retaining pin Safety ring Cap nut Stem Hull nut Backing block Hull Marine Fairing sealant D5566-1 Figure 2-7: Seating Dry Fit for Fairing WARNING: If a fairing is used, the anti-rotation bolt must be installed to prevent the fairing from rotating when the boat is underway. Dry fit the transducer to locate the hole for the anti-rotation bolt. Thread the transducer cable through the large hole in the fairing and through the mounting hole in the hull. Seat the transducer firmly in the recess in the fairing. Note: The transducer must be flush with the fairing. If it is recessed more than 1/64" (0. 5mm) inside the fairing, you may carefully file or sand the fairing flush with the transducer. WARNING: Always wear safety goggles and a dust mask. Attach the drill bit to your drill appropriate for your fairing: Fairing E26017 E66023 E66025 E66034 E66045 Used with Transducer E66035 E66020, E66029 E66024 E66033 E66043 Drill Size 3/8" (10mm) 3/8" (10mm) 1/2" (13mm) 1/2" (13mm) 3/8" (10mm) 24 Transducers for Fishfinders 4. Slide the transducer's stem with the fairing in place into the mounting hole. Be sure the triangular recess in the fairing is pointing forward toward the bow. While holding the assembly in place and using the bolt hole in the fairing as your guide, drill a hole through the hull for the anti-rotation bolt. Remove the assembly and cable from the mounting hole. Sand and clean the area around the hole, inside and outside, to ensure that the sealant will adhere properly to the hull. Metal hull - Remove any burrs around both holes with a file and sandpaper. Anti-rotation bolt Nut and washer BOW Backing block D5565-1 Triangular plug with curved surface facing outward Fairing Figure 2-8: Using a Fairing and Backing Block Seating 1. Remove the transducer from the fairing, if used. Stainless steel transducer in metal hull - Slide the appropriate size isolation sleeve over the cable and onto the stem of the transducer as far down as possible (see Figure 2-3 ). Be sure the top of the isolation sleeve will be below the top of the backing block to prevent the sleeving from interfering with tightening the hull nut. WARNING: To prevent electrolytic corrosion, never allow direct contact between a stainless steel transducer and a metal hull. Chapter 2: Installation 25 3. Apply a 1/16" (2mm) thick layer of marine sealant to the sides of the transducer that will contact the fairing, if used, and up the stem 1/4" (6mm) 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 (see Figure 2-7 ). Stainless steel transducer in metal hull - Apply the marine sealant to the outside of the sleeving instead of the stem itself. If a fairing is used, thread the transducer cable through the fairing and seat the transducer firmly within the recess in the fairing. Apply a 1/16" (2mm) thick layer of marine sealant to the surface of the fairing that will contact the hull, if used. Attaching the Transducer 1. From outside the hull, thread the cable through the mounting hole. Push the stem of the transducer (with the fairing in place) into the mounting hole using a twisting motion to squeeze out excess sealant.
