Leaking drain plug flange
The flange for the drain plug at the bottom of the transom in my boat has
been leaking (not the plug itself) and has been a difficult leak to find. But after some searching and using mirriors to find it, the next task is to fix it. Now that the boat is out of the water (for the winter), I removed the flange being held on with 2 self tapping screws and a long bolt. I was surpised not to be able to see any sort of sealant around the flange where it mounts onto the fiberglass, so I am quite confident this is where the leak was. Beyond using the typical RTV sealant, does anyone have an alternate or possibly better recommendation? FYI, it is a 1986 Dearay Sundacer.

Mark (the rail & canopy hook guy) www.ripnet.com/vtf/prod03.htm I'd use something rated for underwater fittings, on the order of 3M's 4200, but not 5200. LifeCaulk is another good one. Never use silicone under the water. In fact, I have exactly one use for silicone: I bed the portlights with clear LifeSeal. -- Jere Lull Xan-a-Deux ('73 Tanzer 28 #4 out of Tolchester, MD) Xan's Pages: http://members.dca.net/jerelull/X-Main.html Our BVI FAQs (290+ pics) http://homepage.mac.com/jerelull/BVI/ |
