max -prop

[mike buchan]

Hello

Wonder if anybody can help me. I have a Yanmar GM30 with saildrive.

I've just bought 16" max-prop.

Does anybody know the correct pitch set up for this engine/prop configuration.

Engine achieves 3600 rpm but I believe this drops to 3200 with saildrive leg fitted.

I believe correct pitch is around 18 degrees but if anybody has the same set up and has experimented with different pitch settings I would welcome any advice that they could give me.

Thanks.

I think it'd be whatever gives you the engine manufacturer's recommended RPM when the throttle is wide open. If you have a question about what this is you should contact a Yanmar factory technician.
