Which outcome occurs when a marine propeller experiences extensive cavitation near the blade tips?

💡 Explanation

When cavitation occurs on a propeller, vapor bubbles form and collapse violently because rapid pressure changes reduce local pressure below the liquid's vapor pressure, which reduces thrust and generates noise and vibration. Therefore reduced thrust and vibration results, rather than increased efficiency/speed, which require stable hydrodynamic conditions.
