Re: Want to do transom
This question comes up all the time. Unfortunately, if your transom is rotten the only safe option is to replace it correctly. Adding plates or attempting to reinforce it is a gamble at best.
The work it will take to replace half of it is the same as the work to replace all of it. So you may as well do the whole thing and do it right.
There are other things to consider as well. The majority of boats needing a new transom will also need structural work under the deck. It is likely that the stringers and possibly the deck core itself will need repairs.
I know it is hard to face, I had a hard time accepting it myself. However if you go ahead, bite the bullet, and get it fixed right, you end up with a boat better than new.
Then, you can justify a new engine, controls, sounder, lighting, electrical, bells whistles, rocket launchers, sirens.........
Make it happen Captain!
enjoy
