Re: New prop test results
The max-power for the inline-6 is variously listed as 5000-6000 rpms. With all of my I-6 motors, I have aimed for 5800 as my target max rpm. Some of the newer I-6 (newer being a relative term) motors achieved rated hp at lower rpms with the new IC ignition systems.
Check the specs on your particular motor. Try to find a prop that gets you the maximum rpm of the maximum recommended rpm range while your boat is at max load. Max of max at max.
Note: This is NOT the most efficient setup for fuel economy.
