Our redesigned anti-cavitation/ventilation plate will add power and control, and prevent 'ventilation' on any one of our long tail shafts.

Installed in minutes, the top mount anti-cavitation plate comes with all hardware and is solid stainless steel.

This product will fit any one of the Mud-skipper Thai long tail shafts.


Ventilation is a phenomenon that occurs when surface air or exhaust gas (in the case of motors equipped with through-hub exhaust) is drawn into the spinning propeller blades. With the propeller pushing mostly air instead of water, the load on the engine is greatly reduced, causing the engine to race and the prop to spin fast enough to result in cavitation, at which point little thrust is generated at all. The condition continues until the prop slows enough for the air bubbles to rise to the surface.The primary causes of ventilation are: motor mounted too high, motor trimmed out excessively, damage to the anti-ventilation plate, damage to propeller.
