Outboard Anti-Ventilation Plate

Anti-Cavitation Plates Prevent Exhaust Gases.


Anti-ventilation plates protect the engine performance from the gases being pulled into the propeller blades. It can cause the prop to grip on the water, the engine revs and speed starts to decline. The main purpose of the anti-cavitation is to prevent surface air from being sucked into the negative pressure side of the propeller blades.
