I have a minor water leak in my 14' Lund right where the transom meets the hull. Saturday I fished Erie, noticed a small amount of water seeping in at the floor. Saturday evening I dried it out untill it was bone dry. Sunday morning I'm back on the water watching very carefully where the water is coming in. So Monday I'm at CTC, purchased an epoxy/aluminum putty stick called Starbrite. You break off a small piece, knead it in your hands & I pushed the product into the small crevices from outside of the transom. I found out later that this epoxy dries rock hard. With some vibration of my boat hitting waves & vibration from the motor I feel the starbrite is going to crack. I feel I'm going to need a rubberized pliable sealer. I looked at the 3M sealers they have but the instructions stated not to be used below the water line?? Or are they referring to a situation where the boat is in the water 24/7? I also looked at the marine Goop. I've used Goop for other repairs & found it to be quite good. What are your suggestions guys? Have you ever used the Starbrite epoxy stick?
