Hi,

I'm trying to find a better pitch for my ground adjustable prop. When I change it, I think I also should have a look at the MAP. Could you tell me what value it should ideally have?

Best regards,

Jo

Hi Jo,

We don't have a full set of MAP charts for the engine, but as a guide, try the following: At about 4500ft cruise (2850- 2900 rpm) about 22 inches for 4cyl and about 20 inches for 6 cyl.

Regards,
Doug.
