To Aaron's request below: The electric motor I chose is the Electric Yachts, Inc. 48V 3 phase 10HP. In speaking with them and Martec, the prop selected was a 14 x 12 as the SHAFT turns over at about 1400 RPM.
I picked this combo after a fellow in my area did the same about 3 years ago on an identical 1974 35-II which I then saw in action and felt for my kind of use would be ideal. There are 4 ODYSSEY AGM 12VDC batteries running in series to drive this, plus 2 additional house batteries running in parallel. Separate chargers for each and currently only connected to shore power. So, to the domino effect. Changing the engine necessitated a new prop shaft and prop one for length and the other for the correct torque to RPM match. Then when I finally got my new shaft back and installed, I slowly twisted on the packing nut to the stuffing box and noticed it was not concentric any more which was probably due to the old motor settling on its mounts and pushing down on the old stuffing box. Needless to say, the old shaft is scored where it meets the stuffing box nut. All the notes on this site as well as two others, are divided down the middle with respect to PSS vs traditional stuffing boxes. Given how I did allow some room around the existing box and could fit an identical replacement in there, I think I will go with that and the high tech packing material.
