Look into a galvanic isolator. Also, unplug your boat from your AC circuit when you leave the boat. In other words unplug your shore power cord.
Other than that you might need to consult an expert to run some tests.

Galvanic corrosion can be a big problem. I had one guy call me from the Bahamas once because everything metal in his boat was disappearing before his eyes, it seemed (even his running lights). Make sure your boat is bonded correctly (all underwater metal fittings should be bonded). Also make sure there isn't a problem with stray current coming from another boat near you in the marina. Someone else could be causing the problem. I'd check the pencil anodes in your engine too, if you have them.

Thank you for this info. How do I check for stray currrents fro another boat.
