Re: When I start to fiberglass ??
Are you using marine grade plywood? Hopefully!<br /><br />You should coat both sides with resin, and do the corners twice. Wet out a layer of 1.5oz mat on the transom skin and a layer of 1.5oz mat on the side of the plywood that is going to go against the transom. Just as it starts to gel, mix up a batch of resin/cabosil/milled fibers to peanut butter consistency and trowel it on the transom skin and plywood with a 1/4" notch trowel. Make sure to get it really thick around the corners. Then clamp that sucker into place. The excess putty will ooze out the corners, get a tablespoon or peice of pvc pipe and use the excess putty to make a fillet around angle where the transom meets the hullsides and bilge.<br /><br /><br />How big of boat is it, or how large of an engine are you hanging? Unless its small, you will need two sheets of 3/4" plywood.
