I have a 1973 21 foot Boston Whaler Outrage that has a CP1000 conbination GPS/Fishfinder.

I went with the transom mount transducer and was somewhat satisfied with its performance. (What I mean by "somewhat" is that I had to tweak it a lot during installation, and sometimes I would lose readings at cruising speed and never really got good "fish finding" readings unless stationary)

Long story short, a friend was climbing into the boat and used the transducer as a step. The transducer is broken, and now I need to replace.

I was seriously thinking of doing a thruhull transducer. I was thinking of mounting it in the bilge. There is about a thickness of 2-3 inches of foam and fiberglass from the bilge to the outside of the hull. I am confident I could install without complomising the hull integrity.

My question is whether there would be any advanctages to the thruhull installation.

should there be better performance (I think so)
Is there increased risk of damage (being mounted on bottom)


Just wanted to know if anybody has done this and what they think.

Thanks in advance.
