[. . . ] Never use ketone-based paint since ketones can attack many plastics, possibly damaging the transducer. Reapply paint every six months or at the beginning of each boating season. It is easier to apply antifouling paint before installation, but allow sufficient drying time. As illustrated in Figure 2-6 paint the following surfaces: Exposed area of the housing, including the acoustic window Bore of the housing up to 1¼" (30 mm) Outside wall below lower O-ring Exposed end of the paddle wheel insert Paddle wheel cavity Paddle wheel Blanking plug below the lower O-ring and the exposed end Housing Paddlewheel insert Lower 'O' ring Paint exposed housing and bore up to 1. 1/4" (30 mm) Paint outside wall below the lower 'O' ring including exposed end, paddlewheel cavity and paddlewheel D4859-2 Figure 2-6: Applying Antifouling Paint 22 Transducers for Fishfinders Installation Note: To install the thru-hull transducer in a cored fiberglass hull, follow the instructions in Installation in a Cored Fiberglass Hull on page 29. Drilling Holes WARNING: Always wear safety goggles and a dust mask when drilling. Drill a 1/8" (3 mm) pilot hole perpendicular to the water line from inside the hull (see Figure 2-3 ). If there is a rib or strut near the mounting location, drill from the outside. If the pilot 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. Cut a hole from outside the hull: Fiberglass or wood hull ­ Use a 2" (51 mm) hole saw. Aluminium or steel hull ­ Use a 2 1/8" (54 mm) hole saw to accommodate the isolation sleeve used to prevent contact between the stainless steel housing and the metal hull. 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 a mild household detergent or a weak solvent (alcohol) before sanding. Remove one safety ring, the retaining pin, the cap nut, and the hull nut from the transducer (see Figure 2-7 ).

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. 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.
