I just bought a 95 201 pro with a 01 merc. 225, it has a Yamaha prop 27p. I am getting about 62-64MPH at 6k RPM. I don't think the tach is right because it doesn't sound like the motor is running 6k RPM and there is very little rooster tail. And the 6" jackplate is all the way down. (How I bought it) I just ordered a 27 tempest prop and going to try that. What should I be running speed wise, and is the prop going to make any difference?
