Transom Repair

36572This is my first transom repair, so I'm hoping to get some advice. I started this by cutting the stern on each side of the storage compartment, drilling out the rivits and removing the top section. I then cut out the inner transom wall and removed the rotton wood. There was a middle sheet of fiberglass, so I cut it out and removed the wood on the other side. After a couple of days, spread over a few weekends and some homemade tools, I removed all of the rotton wood completely from the transom. I am considering reattaching the back piece of fiberglass and cutting two pieces of plywood to fill in the gaps and then using a epoxy filler to fill in any spaces. I have reading articles from, The Rot Doctor and Seacast. After reading some post on seacast, I'm not to sure about using that. The transom will support a 30hp Johnson. Any advice would be a great help.

Build it like the original and it will last you another 25 years. Cut two layers of 3/4" plywood. Exterior AC works fine. Put a layer of 3/4oz mat on the transom soaked in polyester resin and set the first layer of plywood on it. You need to screw and or clamp it tight. Let it set overnight and then put a layer of mat soaked in polyester and screw the second layer of plywood with 1 1/4" galvanized drywall screws. Put about three layers of 4" wide mat on the edges and two layers over the rest. Drill and install a new drain and you are done. Epoxy works fine, but it is goldbricking,
