Location: Angola, IN | I think 5k rpm's is plenty. The max may be 5500 or 6000 for this motor. Not sure. You could find out easily I'm sure on on iboats.com
So a 15 pitch should theoretically get you to 5350 rpm's and approx. 38 mph according to my calculations. How are you measuring RPM's? OEM dials are notoriously inaccurate. You might already be maxed out, or you could only be at 4k at WOT.
A good gauge directly linked to your ignition is worth checking out before you over rev your motor. |
