Tom, I have absolutely no idea how many hours. To the best of my knowledge it is the original and the previous owner did not leave her unused for any significant duration. So engine hours is 25yrs. ;-)
I did find a scrap of exhaust gasket in the bildge and had heard from others at the marina that the PO had blown the head gasket. He seemed like the type (most sailors) who would try to do the head gasket himself.
