For some years now I have a Zercom 165 fishfinder. At the time I
bought this particular unit because it was supposed to have a good
performance at high speeds. With the unit came a transom mount
transducer. So far I had poor results with it. It performs very wel at
low speeds but as soon as a come on a plane the reading gets flaky and
at a a speed of 25 knots or more I get no readout at all. I already
tried relocating the transducer, trying to find a spot with less
turbulence, but with little or no improvement.

Now I'm considering moving it to the inside of the boat. I suppose I
could mount it in the bildge, fixing it with some epoxy or sillicone.
Is there anyone out there who had similar experience or who could give
me some pointers in order to solve this problem ?

Many thanks in advance
