I have a great 1980 Monark aluminum side console. It is a great boat, but the wood in the transom is rotten. It has the decked rear so there is no way to get the rotten wood out to replace it. Does anyone have any experience with this? I was thinking of getting a 1/4" steel plate made and bolt it to the outside of the stern, but I am not sure that will work either. The access hatch on the rear deck is exteremely small so I dont know how I would tighten bolts, etc.
Any advice would be greatly appreciated!!!

You may still be bolting into the bad wood with a steel plate, and it will be heavy. I don't know what access you have on the inside, but I suspect that you can removed the bad plywood, by cutting larger access hatches in the aft deck, then put this back together after you have repaired the transom. In fiberglass boats the outer or inner skin of glass is cut off. Most aluninum boats do not have an inner aluminum skin, just the bare wood.

the boat is a 17 or 18 Monark, registration says 18 but I think it is a 17. It has an old 70 2 stroke evinrude on it. Here are a few pictures.
