Thanks for all the helpful comments and thoughts. Luna's problem is that
she cruises under power at about 5.5 kts at 1500rpm, but starts to smoke
and overheat above that. She'll do about 6kts at 1800rpm. Next time I

Re: Stus-List PROPELLER PITCH
Call Fred at PYI, he is a veritable font of information. You'll need to know
the prop diameter and transmission reduction; he will have a table with your
boat and engine on it. He was terrifically helpful when I put the new engine in
Peregrine.
Your engine manual should have a max achievable RPM listed. If you mash the
throttle and can't get to that RPM, you need to dial in finer pitch.

With a standard 4.61 transmission ratio, I use a 17" Max Prop set to 10
pitch (18° blade angle). 2500 RPM gives me 6 knots in fairly smooth water.

While motoring in forward gear, run the engine at full throttle. Your
engine should be able to reach maximum, or close to maximum rated rpm. If
not, your pitch is to high. If the engine runs much higher than maximum

Be sure you know your transmission ratio, prop-hull clearance, ideal engine
RPM, etc. before you rely on a simple calculation. This is a question that
seems like it should have a simple answer but "...it depends on several other
parameters.." so a simple answer could be wrong. If the Max-Prop a

Luna is a 1984 C&C 35 with a Yanmar 3gm30 engine. Does anyone know what
the proper propeller pitch should be? She has an aftermarket Maxiprop,
and based on engine performance, I believe the pitch may be set too high.
