Adjustable cavitation plates are a game changer! Adjustable cavitation plates allow Thrasher’s hull to plane out faster and hold on plane at full throttle. Where adjustable jet trim changes the attitude of Thrasher's hull as a function of thrust; cavitation plates change the attitude of Thrasher's hull as a function of hull speed. Adjustable cavitation plates allow you to adjust your jet trim higher to force the jet intake into the water with greater force, reducing porpoising and cavitation. These adjustable cavitation plates coupled with our adjustable jet trim produce unprecedented handling! These are a must have; once you run them, you will not want to go back! Compatible with Thrasher V3 and Thrasher 27. This is for the port side adjustable cavitation plate only. See the adjustable cavitation plates - installation kit if your Thrasher does not yet have cavitation plates installed.
