Hello, I have a 18' 1989 Bass Hawk boat that has a rotten transom. I have done some reseach (thanks to all post, pictures and replies) and have a good idea what I'm getting into. However, I need some advise to help me determine weather I should remove the top of boat by cutting the top off about 3' up from the transom or cut the back out to expose the wood. I first wanted to cut the top off and go into from the inside but looks more difficult vs. going from the outside due to the design. Also, both sides of the rear angles toward the front. Is this part of the the transom or is the flat portion where the motor is mounted just part of the transom? First time major boat repair for me so any advice will be greatly appreciated. Please see attached pictures. Thanks to all.
