Andy,
I know you have tested Octura 2167 props in the past. I have two identical 2167 propellers , one with 5.000" leading edge pitch X 7.000" trailing edge pitch. One with 5.125" leading edge pitch X 7.500" trailing edge pitch. The first blade runs 78+ MPH at 20,000 RPM & is very smooth on the oval course. The higher pitch blade causes the tail of the boat to hop up & down slightly. Do you have any ideas as to what would eliminate this problem? The thrust angle is zero for both & both are running at the same strut depth.
