So moving to a larger prop and shaft and it seems the prop is aweful close to the rudder, maybe an inch? Is there a minimum distance that is preferred. Could not have been too much more than that with the old set up.

Re: Spacing between prop and rudder
My 32 has just enough room to sneak the prop off, if you tip it just right. That is original as far as I know. The 32 that I just re powered with 1.250 shafts was about the same. It had a little more room but only because the shafts were set up for castle nuts where mine are jam nuts. The castle nut shafts are about .500" - .750" shorter from rear of prop hub to end of shaft.

Re: Spacing between prop and rudder
In theory, the space between the back of the prop and the cutless bearing should not be more the twice the diameter of the shaft.
