2012 Yamaha F150 on a NauticStar 2110 Sport?

What is the 15-1/2' x 17" prop you have acquired? If it is a Yamaha Saltwater Series II, the F150 is not going to be super happy with it; that is a big prop and prop rattle and shift clunk may be a problem, even with the SDS hub.

Ah, Michigan. It's their version of the MIRAGEplus, but not as good.

There are better and more suitable props out there. And no, I do not recommend the MIRAGEplus for your application.

trying it will not screw anything up, but it may clunk and rattle a lot at idle speeds.

What RPM and speed did you use to get with your aluminum 17 pitch?

Here is yamaha's test on that boat. Its the "bay" version, but the hull appears to be the same to me.

Notice they used the smaller diameter, Yamaha Reliance, 19 pitch.
But you may load heavier or something, and want to run a lower pitch prop. we don't know.

Powertech props have a couple options, I like the SFS3.
They actually just came out with their version of the reliance which runs almost identical, but cost less.

Tom probably has some Stiletto props that would work well for you.

You can try that Apollo, but as Tom said, there are definitely better choices for you.
