1979 lund mr pike, trying to get the transom core out for replacement. I have ALL bolts (there were six on the bottom of the wood and four on the top) removed. There are no rivets holding this wood in place. I am unable to pull the core out by hand (obviously, or I wouldn't have made this post ) And so far, drilling 3" deck screws in and lifting with a claw hammer doesn't work. any suggestions for getting the stupid thing out? I can see down along the core on both sides and can't see any hidden fasteners holding it in.
