Thanks Mark, that's what I did also, it works fine! Thanks for the help!My original Signet depth sounder transducer (a standard Airmar transducer) is stuck to the inside of of a flat spot on the hull with clear silicon caulk.
It has always been that way. I just redid the silicon a couple of years ago.
The depth sounder has always worked fine.
This saves a hole in the hull.
