Recommended RPM…

[Justaguy10825]

Hi All! I have a 1994 Suzuki 150HP EFI on my 1994 Sweetwater Pontoon. I am trying to find out what the proper prop would be for the boat. Right now it has a prop that is way too big for it (16” x 21 Pitch stainless) Does anyone know what the recommended RPM for this engine is? Thanks!

You can try a 17 pitch alluminum.

5000-6000 rpm full throttle, all approx. but run it at full throttle check rpm and for then work out from
1" Pitch = 200 RPM + -
Lower pitch to gain RPM
Increase pitch to lose RPM
Hope this helps size and no. of blades affect it as well.
