NSTALLING THE ISHFINDER
To permanently install the transducer:
1. Lightly sand the surface of the hull and face of the
transducer with 400 grit wet or dry sandpaper.
2. Build a dam using strip caulk about 1/4" (6 mm) tall. Pour
about 1/8" (3 mm) of two-part, slow-cure epoxy into the
dam.
3. Place the transducer in the epoxy, turning the transducer to
work out any air bubbles.
4. Weight the transducer in place, and allow it to cure for
24 hours.
