Don't confuse DRY mahogany with DRY ROTTED mahogany.When I reworked the wood in my 13, the side of the console (where it contacted the sole of the boat) and the backing piece for the side of the console (sole plate?) (which was in contact with the sole ) were both badly dry rotted. It is easy to tell. If you can make a big dent in the wood with your fingernail, you have a problem. Also, if you can sand large amounts of wood off very easily, you have a problem.
If you have a small amount, you can approach the problem like a dentist: Sand or cut out all of the rot and fill it in to the original contour with some sort of putty. There are pros on this board that will have a lot of suggestions.
If you have a large amount of dry rot, I suggest that you fabricate a replacement using the old piece as a pattern.
I ended up replacing the two pieces mentioned. Since mine is a fresh water boat, I glued up a piece of cypress to the right width (using buscuits to join the pieces). It is not very pretty (and I painted it), but it works.
Why cypress? Mahogany will not rot in salt water. It will rot in fresh water. Cypress will not rot in fresh water.
Good luck,
