"Robet, If the wide open RPM is at or near the maunfacturer's suggested max RPM, you are propped correctly. If it is low, you need a prop with less pitch. If the RPM is high, you need a prop with more pitch. After you have the correct prop, adjust the trim angle of the motor. More trim means more speed, until the prop blows out. Also, the antiventilation plate should be even or up to 1" above the bottom of the boat, for best performance."
