Rpm issues

Thank you. That gives some assurance I’m in the ball park..I think I will re-pitch the prop to 48 at some point

On the C-85 max RPM book is 2575 . My recent Ercoupe had almost identical performance as yours . . .
2200 RPM static
McCauley 7150 prop
Max cruise I got was 2450 RPM full throttle , I have been told the prop pitch dictates max RPM
engine 150 SMOH
I cruised @ 2200 RPM 5gph (I have mixture control cable) 110 MPH

Sounds like a plan.
Take care

Yes it as an illegal prop. Previous owner forwarded funds, so bought the new McCauly I might have it re-pitched this winter to a 48 in SEA

Thank you for your input
