Finally bought a 15hp johnson

Re: Finally bought a 15hp johnson

So I have a 15hp prop? What is the max rpm on these?

Probably, but I can't say for sure without a part number or dimensions. The 15 hp prop is 9x11 whereas the 10 hp is 9x8. RPM is 4000-5000.

Thought I'd edit to add that the 1957 18 hp prop is 9 1/4 x 11, which is not weedless so it has the broader blades we are accustomed to.

Now I can't wait for the weekend...gotta know how the weedless and a 'screamer' does on the old 15. Thanks for clarifying that.
