I'm starting to rebuild a 77 ranger Fish & Ski. I started removing the wood in the transom, No problem. I'm thinking of taking the cap off the boat. I've checked the stringers(good) I'm at the point were if I dont fix and make sure all is good under the deck it will **** me off. I rather do it all, than kick myself in the *** later . My question is should I replace the transom with plywood or pour Seacast what is the best?(strongest) The transom glass inside and out doesn't even have a crack in it. I'm not in a rush to get this done.I bought this boat to restore, It will be like new when I'm done. I would appreciate any suggestions. Thanks!!
