86 Tsunami Transom Rebuild

[Capt_Mac]

Spent pretty much the whole day on the computer and phone talking to people, sounds like I'm doing this backwards. From what I understand I should have taken the inner skin off then put in the core and glass in and work out the right angles which supports the weight and the motion of the motor on the transom. Looking at the pictures, the wood never went down to the bottom and the only thing holding the transom vertical was foam and the grey filler. The foam and grey filler were on all three sides and then you had the fiberglass and core. Will I be okay putting in the core then shot foam and epxoy filler on sides and bottom then glassing the outer skin? or should I cut the angled sides and then angle the core and glass in? Or do some more cutting? Every hole I drill on this boat their is foam. With that said their are no soft spots and the only thing wrong is the transom and some moist foam.
