Bob, I looked over your shaft removal thread, which will certainly make me feel less alone when I'm pulled out my hair. Unfortunately, my set bolts from the coupling's hub are proving more difficult than yours, but then my stuffing box came apart more easily, so there's that. I appreciated the deepblueyachtsupply.com referral, as I wasn't aware of them. I would've thought a new shaft would be a lot pricier. I take it, though, that just cutting the old one just aft of the coupling would be a lot tougher than you'd first thought.
