⚓🛟 Cavitation VS Ventilation, what you need to know.🛟⚓

Understanding Cavitation and Ventilation in Boat Propellers.
Cavitation and ventilation are often confused but are crucial phenomena affecting boat propellers' performance.
Ventilation occurs when surface air or exhaust gases enter the propeller blades, reducing thrust and increasing engine revolutions, leading to erratic handling and loss of control at high speeds. This usually happens when the propeller is too close to the surface, during tight turns, with a high-mounted engine, or due to poor propeller selection.
Cavitation happens due to low pressure at the back of the propeller blade, causing water to boil and form vapor bubbles. These bubbles collapse violently, causing noise, vibrations, thrust loss, and potential damage to the propeller.
