I have to replace the transom on my 21' Checkmate. Does anyone have some helpful info on where to start? I am repainting boat as well, so any suggestions there as well would be appreciated. Note: Along with wood being rotten, there are cracks where the eyehooks are on each side of the o/b. There are also small hairline cracks where the top 1/2 of the boat meets the bottom at both sides of boat on the side corners. Thanks, Michael
