Also. McMaster Carr sells SS two bolt safety collars that are only 1/2 wide if that helps.

Did you get that shaft from Marine Machine? Did they supply you with that piece of key?

If the seat in shaft has a radius approaching the one on that key, those guys have their shit together.

Look's nice! How do they cut a constant depth keyway in a tapered part of the shaft? Do they use a keyway cutter in a vertical mill cutting from the side with the shaft mounted at the appropriate angle?

thanks for all the help making my decision between you and bob it made life simple i get stuck with too many choices , THANKS AGAIN

GN 369 lost an A 22 shaft and new prop in Sat. race at Parker. I was told it had 6 races on it. I wouldn't run an A 22 prop shaft if was free. K Monel from Italy will be my shaft of choice from now on.
