I have a 19' Regal which has what they call a FasTrac hull. This hull

step that is roughly in the center separating the front and rear
halves of
the boat. This is designed to funnel air under the hull and reduce
drag
providing more power/fuel efficiency with less power. I have the
same
problem with my depth finder at 10+ mph. I have tried filling my
bilge with
water and putting it in there and it does seem to work off and on.
I'm going
to take the chance and epoxy it in. Hopefully everything goes well
and I get
a decent signal. I boat mostly in Tampa Bay and have found myself too
shallow on several outings.



John, if you are able to access it, I would try to epoxy the
transducer forward, just ahead of the step. The step will create
turbulence at low speed, and at planing speed, much of the aft portion
will be out of the water.
Good luck.

I have heard of putting the transducer in a plastic bag full of water so
it can be moved around inside the boat to see where the shoot through
works best.
