Re: How to raise transom..
I'd already written you back and posted before reading further.. After installing the transom, I shot it with a coat self etching zinc primer.. Then applied 2 coats of Behr semi gloss oil based paint.. Then installed the aluminum plates and "end cap", and did the same for them, even painting the stainless steel bolt heads, nuts and washers.. And when the wood finally goes, another 10 days or so re-manufacturing a new one----cut to the correct height (fingers crossed)..!!
I guess you didn't read post #9. Everything I said was for a Fiberglass boat, NOT a Tinner, EXCEPT for the plywood. That was true for any boat. The Birch Plywood, I guarantee is NOT exterior glue. As long as you ALWAYS predrill and coat the holes and any and all mechanical fasteners with Epoxy it should still last many years. Epoxy has NO UV protection so for even longer life, I'd recommend either coating it with a couple of coats of Marine Spar varnish with UV protectants or Rustoleum Professional Oil Based Paint.
