Transom replacement

[muskiedreams]

Mine is a 1990 Grumman and it has a layer of foam in the bottom. the foam looked ok when I replaced the floor about 10 yrs ago. There is space between the top of the foam layer and the bottom of the foam. There is additional flotation in the form of 2x8 styrafoam two layers thick under the gunwales from the transom to the consoles.
