Norm, Living in landlocked Pittsburgh, I don't sail my 15 enough to justify a wet cell electrical system. But I found a fish finder, Pirhana 1 by Hummingbird, that works on AA cells. Amazingly, it will run many hours (20-30+) on a set of batteries (4, I think.) The transducer hangs from a suction cup that mounts on the transom beside, or right ahead of the rudder. No problems when heeling. No holes in the boat. Great performance. Low cost, about $125. Everyone has their winners and losers. The Pirhana 1 is definitely one of my winners.

I've been trying to figure out where to mount a depth sounder on my M15. I've had trouble before on another boat with the keel masking the signal when the boat was heeled over but I can't see a good place ahead or behind the keel. The area just ahead of the keel appears to be very very thick and I don't think behind the keel would leave the thing accessible. Where have people mounted transponders successfully?
