I've been poken around my project (literally poking) to find out the extent of work i will need todo. Some of my transom is soft and black around the lower motor mount bolts. The clamp area behind the splaswell seems fine. I can see bare wood in there. My lower transom area has another layer of plywood, (Rotten), over the transom wall that goes from hull to the transom top. It seems there is a inner skin behind the extra plywood for the lower mount bolts or just a layer of thick resin. Have you guys seen a transom with no inside skin just plywood? It is a 86, 18 foot BAYLINER trophy. No signs of transom bulge or sagging. All I see is some very fine cracks where the transom and splashwell rises up to the top. Too many words I know. Thanks
