I just installed a new prop and wear ring and now it has a tight spot. It's almost tight enough I can't turn it by hand. I took the prop back off and put a drill on the prop shaft to spin it fast but it really don't look bent?? Not sure if the housing could be out of round?? Maybe the shaft is bent just barely and I can't tell?? I know there isn't much tolerance in those clearances. Where should I start now?? Thanks
