Also what is surrounding the shaft log? Meaning in the part of the boat you can't see from the prop to where it enters the cabin near the stuffing box? Is it hollow? is it fiberglass? I'm trying to figure out that if water is getting outside the shaft log, what it might be damaging
I suspect that what you have is a fiberglass tube that is glassed into the hull. Since you don't have a strut, the cutless bearing is installed in the aft end of the tube. I am sure this all solid fiberglass in this area.
