Keeping die electric grease on both the fish finder terminals and the harness plug terminal helps prevent corrosion. Provably just as important is to disconnect the battery terminals before disconnecting the Fish finder that will prevent electrolysis because there won't be any electrical current in the wiring. I go trough and back again in the surf at LJ and have not had any problems following that rule.
