Re: Depth finder

Hi Bob. I installed mine several years ago in the same location you intend
to place yours (slightly more forward). Works very well.

I did not use epoxy. It was suggested to me to use marine goop and make it
approx 1/4 inch or thicker in one solid mass
WITHOUT ANY BUBBLES OF AIR TRAPPED INSIDE.  I then pressed the transducer
into the goop and the deed was done. Has not budged since despite pounding
through waves etc.. To ensure nothing would hit the transducer, I covered it
with a thick round plastic dome. Very important for me since i have added 15
gallons of water ballast in the same area.
