Solid hulls-no problem there. Old transom- may be wet-not such a big issue with the i/b. There have been some extensive restos of inboards on the site. Go back and look at the photos of Miles Offshore's repower and I think the other major project that I remember was Chance-I'm pretty sure that was his screen name.
I'm sure one of them will chime in.
Don't expect a speed demon, but count on a great ride.
