Here are couple of videos you might find interesting. The second is
on rebuilding a damaged or worn shaft.
I don't have a lathe and don't plan to get one; more interested in finding
a really good machine shop that I can trust.

It
looks worse in the photo. I was able to clean it up quite a bit, but it
is worn a bit. I'll try to get some close up photos and post
them.

Your motor shaft looks to have some etching
problems where the seal was. How deep? Unfortunately, that's a common
problem for ceramic rotating seals. Sea water stays in the outer O-ring face
and works away in what becomes the classic low oxygen trap. You might need
some repair work there before reassembly.
