Rich I've had that transducer and plug in and out so many times that
opening a hole in the bottom of my boat has become a relaxed activity.
Larger o-rings stopped the leak. I'm just concerned that the integrity of
the thru-hull has been compromised.

Dennis, it's definitely the housing. I've replaced the transducer with the
blank plug and same same.
I haven't gotten to the depth instrument yet because I have an airmar
through-the-hull one installed and I'm hoping it works with that one.
Haven't yet tested it however. The instruments aren't yet mounted I just
did the thru-hull because it was a pre-launch requirement.
