Hello, does anyone know what this material is in my transom? It looks like it maybe seacoast or something like that. Also looks like they poured the material in between stern side fiberglass and a layer of wood AFT side which is fiberglassed over only AFT side. looks like the fiberglass delaminated from the material or job was just poorly done. Transom does feel solid and only sign of problem was the edge cracked and when I lifted it I discovered this mess. I would appreciate anyones opinion on how the handle this. Should I just cut out the inner section of transom and redo it or can I just use some penetrating epoxy and get it to stay together and make a stronger surface for the fiberglass to stick to?
