Default prop bolt ?
I'm buying a replacement crankshaft and need to tell the technician which size prop bolts I will be using with my fixed pitch prop. It appears that 3/8 and 7/16 are both available on the Sensenich 80" pitch prop I plan on using. Is there an advantage to either one? Thanks Jim.

Use 7/16" bolts for 150/160 hp. 3/8" are OK for 150, but if you have a choice, go with 7/16". Anything over 160, go to 1/2" bolts.
