Hello,

I really like my 1981 Baja 16SS so I want it to last forever! However, I need to replace the transom. As you can see in the picture below, the wood is rotting and brown liquid is seeping out of it. Also, the gelcoat is cracked under the motor mount and the previous owner did a temporary repair. I would like to rebuild the transom from the outside. It looks difficult to do from the inside because the splash well is right behind the cap and there isn't much space. I don't want to separate the hull halves. I have some fundamental confusion regarding this process and any help would be appreciated.

The rear of the boat from the bottom to the cap (down the middle) is only about 34". It is 76" across at it's widest (where the halves meet). The cap is 2.25" thick and spans 34" in the middle (see pics). I understand that I need to measure in some distance to where I will be grinding into the rear to remove the skin and access the transom, how far should I measure in? Will there be enough of a hole to put the new transom through? It just seems small back there!

I would like to use coosa board. What should the layup be or how do you decide that and how do you plan for the final thickness of the layup?

Anyway, check out the pics and thanks for the help! (pics below)

What a struggle. I promise if I can figure out how to post pics I can build a transom.

If the transom is rotting then most likely the floor and stringers are too, so if you want to keep it for a long time all of them at the same time.

​If you knew that ONLY the transom was bad, then doing it from outside would make sense, but if the floor and stringers are rotten then it all has to come apart anyhow, and in that case it's much easier to do the transom from the inside.

Thanks Ondarvr, it has one stringer but it doesn't start until partway up the deck. The floor is fine. So yes, only the transom is bad and that is why I am doing it from the outside.
