Two weeks ago I removed the rotted wood from my transom. It was completely rotted through in the splash well engine mount area. After reading many threads concerning this repair I decided to use Marine Grade plywood instead of Seacast.
I know many said they have had satisfying results using "non pressure treated exterior plywood" instead of the way more expensive "marine grade". Being that Seacast was out of my budget I decided to go with the marine grade based on the information from our local lumber supplier. The shear strength of marine grade is significantly stronger than than the ext ply of the same thickness with no voids between plys.

So after purchasing the plywood I used the inside sheet metal of my transon for the pattern, cut the wood (2 pieces), glued them together with "Gorilla Glue" and screwed them together. I then did a test fit into the transon area and noticed it was very snug fit! I removed the new wooden transom and I used epoxy resin and sealed the entire thing. Next I glued the inner transom sheet metal to the wood and screwed and clamped it together until cured. As tight of a fit it was on the test fit I'm concerned it is going to be extremely tight on the final installation. Does anyone have any suggestions on the installation? Thanks.

If the fit is too tight get the ol' belt sander out and sand the edges down so it is a nice smooth fit, then reseal the edges, then install. There should be a bit of play in the wood fit anyway for the expansion and contraction of the aluminum hull. your boat is a little bigger now than it will be this winter. Having the wood too tight now could likely cause problems in a few season changes.
