Fiberglass question

My opinion, it looks like you should have used a little more resin. From the pictures of the outside of the transom you look to have some dry edges and once you wet it out it should have had a clear appearance unless I am missing something.
The wood replacement looks tight. You should definitely glass over the top of the transom as resin alone will crack and allow moisture to get to the core. What year is your 20? and how did you remedy the stringer rot?

1975 V20, planning on sistering new resined marine ply thu bolted, then glass over both and also glass to transom. In that pic of the outside I hadn't put any resin on yet except enought to wet it out, needs more coats then fairing. Planning on glassing the top also. Thanks for all your comments, it all helps.

the 2 inch transom is scary most boats with a rating of 200 hp or more has a min of 2 1/2 transom.

My 20 was rated for 200 or more and it had 1 1/2" core from the factory. It did have an east 1/4" worth of glass on the outside and a courtesy layer on the inside maybe 1/8".

The boat's transom was less than 2" from the factory

It does not sound like much but that is how I remember it 10 years ago.LOL

I thought I laminated 2 sheets 3/4" plywood together and it was a good match for what was there originally. I added some knee braces and made my 20 into a full transom boat with bracket. It is holding up good even with a 250 stressing it out.
