Hey All,<br /><br />First off, the actual drain plug itself isn't the problem. I have a fiberglass boat. There is a metal sleeve that fits into the drain plug hole at the rear of my boat. This metal sleeve is a little loose. The water comes in from between the metal sleeve & the fiberglass. I tried waterproof caulk. It helped a little, but some water is still leaking in. It's not a big problem... ( I get about a gallon of water in after an afternoon of boating). But I'd still like to get a tight seal. My boat doesn't have a bilge pump.<br /><br />Any advice on what to use that will bond the metal sleeve to the fiberglass? Is there a marine product out there for this job?<br /><br />Craig<br /><br />
