Hi Billy,
I've communicated all via email with the exact information presented previously and copied herein.

I calculated my shaft length to be 45 3/4" long with the following beyond the strut (1" diameter shaft):
-standard SAE taper 2 3/4"
-standard SAE beyond the taper 1 3/4" (leaves room for threads and cotter pin)
-1" space between prop shaft and strut

for a total of 5 1/2" beyond the strut.

My prop shaft guy says I need 4.6" beyond the strut (says that will give me 1/2" clearance between prop and strut).


I'm not sure how much clearer I could have been in my communications.

Thanks,

Steve

That is clear.
I’m sure he doesn’t want to recut a new prop shaft for you. All the places I’ve dealt with have made sure things were right so if it is that kind of business all will turn out well. Is he doing prop too?

Billy, I've got more research to do on the prop but he could provide that as well. Its discount inboard marine which is where I got my motor too.

Thanks again for your help!

Steve
