My motor max RPM is 5500. I know that some will say that I can go more, but I will trust the manufacturers max RPM range. In the long run, I think it would be more expensive to “tune” a prop to run over the max RPMs and possibly damage my motor. I stated in original post that I “can” turn 5600, but I do not do this because of my stated limits.
