That's a good article you posted. I can only hope my tach is off and I'm operating in the safe zone. I better take it to the guy I bought the prop from and see if he has a tach I can try it with. Don't want to burn that engine up. Ferdi aka Fred

if your tac is right then i would say the prop is to big. you should be more in the 5,000 to 5,500 range but check owners manual for the engine.

It wont hurt your motor to run at 3,700 but you are loosing a lot of speed

travel is in inches per each rpm.
