Not at this time.
I thought it was the water pump, but not sure.

Thanx
Its the sea water pump.
I had a situation where that wasn't turning. I was able to free it by hand with a great deal of force, and now it seems to be turning o.k. Should this be replaced given what happened?

You definately want to take it off and check the impeller - in fact, not just check it, but replace it while you're at it.
