Restoration of My 20" 74 Seacraft {Death from Above}

[Deathfromabove]

I removed the rotted layers of wood and glass
-I am down to the original transom that is hard as the day it was made. The original wood is white and looks new. My mind is totally blown now. Lol
Everything put on top of it rotted and from poor glass work
-transom was built up to over 6 inches by someone (name I won’t even mention)

1. Do I remove everything down to outside original transom skin (maybe 30 to 40 percent left and build from there? Original lower area at chines is Sweeeet looking just needs some fine tuning.

2. Tabbing I have been reading and spoke with my local fiberglass supplier
They recommended start with a big 12 inch tab After installing two layers of coosa (two layers my choice)then work smaller tabs
-Yes I know to add filets
-Is a big tab needed?
3.Dumb question can cut out be patched in
Original knuckle head added 3/4 on outside and a 2x6 across the transom cut out
Then laminated three layers of plywood over the inside and cut out then added a half sheet that was not fully knotched to transom pattern where it meets inside liner. He used wood glue paste for wood boats the biaxled over it
-I knew he was a lazy arse wen I got it so I went over his work (which looked good at the time unpainted and faired)
I put on another three layers of biaxyl then Matt and faired it in also numerous layers of tabbing over his (his tabbing looked like an inbred did it)
All in all it held a bracket and numerous motors in some really great and not so great seas underway and anchored
