If you want top speed, there is no equal to a Raker. The Raker lifts the bow and bites well at the higher speeds. At the lower speeds, it can break loose and then you have to back off on the throttle until it catches. Cavitation may be because the Rakers lack a flared end. While looking at your profile, with your 100 HP motor, a 20 pitch Raker may be a better option.
