Pourable Transom?

[wannabee]

I recently purchased a 20' sportcraft that needs deck and transom repair, I have researched endlessly on the types of repairs that can be done with satisfactory results...Complete replacement is out for sure and I have seen countless youtube videos where they pour a poly resin with chopped glass(Seacast) into the voids with great results and I truly believe it works well. my question is... there is still viable plywood at the very bottom 8-10 inches that I cannot get out, I initially wanted to stabilize this with "Totals" penetrating "Epoxy" and then proceed with the poly pour, but I have read that poly resin does not stick well to epoxy and that, along with no way to rough it up down inside makes me a bit nervous about getting a good bond. So that brings me to the conclusion that maybe I should use a "Styrene thinned" Poly penetrant(UNWAXED) to penetrate and stabilize the remaining wood and thus allowing a good bond with the Poly pourable with chopped glass...Any help out there? Thanks in advance

No short cuts, all wood needs to be removed or risk compromising SeaCast.

When I used seacast, I still had to undeck the boat, use a chain saw to remove the wood and still ended up cutting the inside transom skin to be able to clean up the fiberglass surface prior to pouring the seacast

as stated above. there are no shortcuts.

This boat has 3 layers of glass with 2 separate pieces of plywood... so the outside is 1/2" thick glass then plywood then 1/4' thick glass then plywood then another 1/4' thick glass on inside.... we didn't know the transom wood was bad till I started drilling... there were no cracks in the transom and the sea drive extension seemed to have no give.... I just felt that there should be something in between to tighten the bolts good.. When watching the pours and after talking to "carbon core" techs. they claimed I could pour multiple times with no ill effects. So naturally I figured as long as the remaining wood is bone dry and saturated with poly resin it is now more or less Poly laminate and any poly seacast or equivalent poured after would bond as good as doing multiple pours?
