Just left my Lund in the salt water for a couple of days. More holes! Thought we had it figured out the first time. Moved the battery, covered it, lifter it up off the floor, ect. (Previous set of holes was on battery side of boat.) Pulled it out yesterday and there’s holes on the other side now. Right where the floor meets the transom. Tying it up next to an old Chris Craft with no zincs, but it’s on a mooring, and there is a portable generator running. My outboard has a bunch of zincs on it but I’m thinking drill a hole (another one) in the transom tonight and add a zinc to the hull. Has anyone else had or heard of a problem like this? Is it zincs? Or is it my boat? About ready to rip all the wiring right out of there……………Becoming very disapointed with the aluminum boat!!!
