Installing the Fishfinder 340C > Mounting the Transducer

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.
