95 120hp prop pitch

[listonb]

I have a nitro 18 foot fish and ski with a 95 120hp force and was wondering if anyone knew what was the original prop pitch is supposed to be? The prop on it now needs replaced and its not the original. It's a 19 pitch and the guy told me he had no idea what was supposed to be on it, but didn't think it was that size.

Re: 95 120hp prop pitch

There is no "correct original" prop.
The prop is selected to achieve the optimal rpm at wide open throttle (WOT).

Contributing factors are motor mount height, type and weight of hull, load in the boat. Type and design of the prop also factor in. If the current prop is working well, get the same.

You want a prop that will let you hit 5500 rpm at wot with the boat loaded lightly.

If you know the current prop info, and your current wot rpm, you can select your new prop.

What is the info on your current prop?
What are your current wot rpm?

This post will likely get moved to the prop forum.
