Yes. There will be 3 layers of tape on the inside 1 6" piece going down the middle, then one offset to the right and the other offset to the left. On the outside it will be the same, 3 pieces of 6" tape one centered and one offset right and the other to the left. The offset will be 2" over the center and 4" which puts it on new material. Do the same at the bottom of the piece.

Do make sure you glue the new piece the transom.

Laguna20 you must have misunderstood me. I did not mean to give the impression you should do the work from the outside. I was thinking that the part of the transom that is not cored will not be adding much to the overall stiffness. The cored part between the stringers will need to be stiff and tied into the stringers really well.

Fuzz what I am recommending will do the job. 6 layers of 12 oz fiberglass tape plus gluing the new piece of transom in place should do the job.

Just as long as it is stout and stiff. That is all I would worry about. The transom is the last place you would want any weakness to show up at.

Yes sir, glued to the transom then, 6 layers of 12oz. fiberglass tape and another layer of 12oz. over everything tying it to the whole transom.

Okay so my plan is to go back with Coosa. I was going to put 2 layers of 3/4 sandwiched to make 1-1/2 and then tabbing 3 layers of 12 oz on the inside and outside of the stringers and 3 layers at the bottom of the hull. The visa will be epoxied to the outer skin as well. Should I put anything other than epoxy and wood flour between the 2 sheets (mat?) Then 12 oz mat over the hole transom. (Just one layer?).

With the exception of the 1208, 1708 and such mat is not used with epoxy. I have never used coosa so hopefully some who has used it will chime in. For me I would just glue it together just like I would plywood.
