I was also thinking that once I put some wood in there (however much is
required), then I may put a long piece of 2x4, or 4x4 that goes the width of the boat. This piece could be glassed to the inner back, and the floor at the back. If that doesn't add strength then I don't know what will. Again, right now, the top part when the motor mounts is solid, and it appears that the rotted area is about the lower foot... "Bill McKee" wrote in message ink.net... One piece is much better. Those joints in the wood have little strength. "Chris" wrote in message ... So replacing wood with new plywood means I can cut out a shape of any size and replace it with a close to equal piece of plywood correct? Just glass the old plywood to the new plywood, right? No concern over how big a piece of plywood is, etc? I could use two pieces of plywood for one hole? etc It appears I've got more rot than I had expected (although the transom feels strong otherwise). I've pulled out about a 1 foot x 1 foot section around the drain plug and am evaluating whether there will be anymore to go too.. Have drilled a bunch of holes in the lower inner part of the transom to see how far it spreads and allow all the wood to dry up before my final decision wrote in message ups.com... It's too late to do any more than slightly slow the problem by sealing the exposed wooden surfaces of the drain hole. If you like this boat and plan to keep it, you will want to cut the rot out of the transom. Be sure to go a few inches beyond the point where you "think" the rot ends when scarfing in the new piece. You should be able to cut away part of the fiberglass on the outside of the transom and spoon out the punky wood, cut a new piece of the best marine ply you can find, and then glass up the exterior again. This is a great chance to learn from the bad practice of the original builder. Any hole drilled through a wooden member- transom, stringer, etc for the purpose of draining water should have the edges sealed up to prevent water from wicking into the surrounding area and promoting rot. If it were my project, I would cut the drain hole large enough to accept a drain plug with a bronze collar fitting. Seal the edges of the hole with a layer of glass and resin, and then bond the bronze collar into the sealed hole- perhaps using epoxy. One rot gets a foothold, it is relentless. Transom rot on small boats is fairly common, and as most are outboard powered it is double trouble. |
