transom and other stuff

just chiming in
The seacast will be cheaper than wood and epoxy
I used 3 layers of 1/2 plywood coated several times with epoxy resin used about 10 gal total doing my whole project but I feel this is the strongest way. I would be scared to pour seacast because if it does not bond with the fibleglass hull it is just a big chunck of fibergalss floating inbetween the inner and outer hull of fibergalss, also I'm sure the stringers are not connected to the transom anymore and this adds a good support.
I cut back about 3 feet at a time to check my stringers if the stringers are good it would not be that bad of a job just doing the transom. but after this repair I'm sure this repair will long out last me and this boat.
just email me with any questions
