[QUOTE="turbotodd, post: 318561, member: 7376"] I was "in the loop" when Yamaha tested the F25 (4 stroke 25 HP) before it went into production. Trust me...6000 RPM for hours on end isn't going to hurt it!! They ran these things for hundreds of hours wide open. Just watch the max RPM and don't exceed the manufacturer's recommendation. If your motor says 6000 max, then keep it around 6000. Not 6500, not 7000. Not 4500. The closer to the max rec. RPM you can run it, the better off it is for the motor. [/QUOTE]
