JohnnyD, I’m guessing that you have a swing keel boat, since that part of my fin keel hull is bone dry. Sometimes I get a small puddle in the sole next to the galley after a heavy rain, but nothing down below. The original location for the depth transducer on Passage is in the same compartment. You could also mount yours in the Vee Berth next to the forward through hull. This would have the advantage that the depth meter would “see” the rock just before you hit it. Might be a better sitch...

As I described previously, I favor installing the transducer ahead of the keel. One potential issue I've encountered which might be a consideration in transducer location is aerated water. The two situations I've seen cause it were:
Engine in reverse, prop pushing turbulent water mixed with exhaust under the boat.
Bashing to windward through waves, resulting in bubbles passing under the transducer.
On the rare occasions when my water cooled shoot-through-hull installations act up, the first thing I check is water level in the the transducer housing. Topping it up has always fixed the problem.
