You got a great boat. I have the same boat and had the same problems. The boat is molded and a chopper gun was used to produce the hull. He did not have thru hall fittings installed at the motor well or drain plug area (need to install). The floorboard was not sealed ( causing the wood to rot near the drain hole from the bottom up). I have to do a section of my floorboard this off-season. Also, the boat will leak the at the top cover seam. I installed a rubber rub rail and used 5200 to seal it (no leaks in 25 years from that area). I did not cut the fiberglass out of the transom, I removed all the wood and cut a piece of marine-grade plywood to fit.
