Propeller Ventilation and Cavitation
Ventilation and Cavitation are two completely different phenomena that are observed, under specific conditions, during the rotation of the propeller and their understanding is often confused. Both the cavitation and ventilation of the propeller (except in certain special cases) have a negative impact on the performance of our boat.
Ventilation is the result of the entrance of air or exhaust gases from the exhaust outlet (they are drawn into propeller blades) between and around the propeller blades which lead to a sudden reduce of water load on the blades and thus to increase the engine’s rpm and the loss of its grip on the water.
