Got me a 14 foot 40 year old fiberglass boat. Havein a small problem of takein on water. Manufactured by Winner. I have taken marine epoxy and hit a few spots that looked like the contributer to the problem. At the back of the boat at the bottom near the drain hole there looks like what I would call a seam that runs the entire width of the boat. I slathered that up with the epoxy and made it what I thought was tighter than a frogs arse. Still takes on water. Now not alot mind ya but enough that the bilge has to run about every three hours or so for about 15 seconds. I've changed my plug to a brand spankin new one and it is always secured tite when put in. The boat has a keel shield so its not from abusein that end. LOL! In fact I take better care of that boat than I do myself. LOL! OOPS! I refuse to wash it. Sorry DH! LOL! Any thoughts other than a new boat. LOL! I was gonna get a new one this january. Just one problem. The wifes van went belly up so we had to get a vehicle instead.
