I have a 14 foot aluminum V haul boat. Had the 1st run today near Paddy's Hole. Notice lots of water in back of boat, came back in after 2 drifts. My buddy wasn't happy but I didn't want to take chances. Found a small pin hole underneath the battery. Whats the best way to fix this tiny hole?? My buddy had me buy Epoxy paste so we can do both sides, the hole is on the flat part of the boat. Lucky me I guess.
