So I had a feeling the transom may be rotten, it had some wiggle to it with just a trolling motor on it. I figured I should replace it before I put a $1000 motor on it. I cut the inside layer of fiberglass around the back where they put the wood originally. The wood inside was almost gone and soaking wet. Going to cut some composite decking to fit, coat it in resin, then glass the whole back section in. More to come...
