I suspect the 9.5 pitch would be under powered and result in higher RPMs.

You can go to a local machine shop and have a new shaft cut and machined for the prop and flange key.

Consider going to a dripless seal rather than a stuffing box. It will eliminate the shaft wear problem. I had one on Rhapsody and it worked great.
