WTT 13.5 diameter 17P SS prop for 15P

[Olde School]

My lake boat has a Yamaha F115 with a 17P and I want to swap it for a 15P prop to make the hole shot even better.
My research shows the same prop size on the F90 but the F150 is a bigger diameter.

My prop is a 3 blade stainless in excellent condition.

In Port Alberni.

It is also the same prop that is on a F70. Too bad you are on the other side of the border from me as I have one I would trade you or at least loan to you to test.
