Just to provide another data point on the prop discussion.
Engine Revmaster 2100D (65 hp variety). 390 hours total time (since 2006)
Original prop was Ed Sterba 54 x 50. My static rpm was 3200, max was 3400 in
level flight. I used to cruise at 120 mph at 3100 rpm.
Just recently changed to a Ed Sterba 54 x 54. Much better for my engine. Static
RPM now 2900. I can now cruise at 3000 rpm at 130 mph. Feels much better on the
engine. I was never comfortable running the Revmaster at 3400 rpm at max
throttle.
I do believe there are major differences in Prop manufacturers. I stayed with
Sterba because I knew the replacement would be consistent with that
manufacturer. He also makes pretty good props - love the leading edge
protection.

My KR2 with a Revmaster 2100D has a Sterba 54X50 prop and my static is still
too
high at 3400 RPM. Maybe you should check your engine to see if it is putting
out all the power it should.
