Which risk elevates near a marine propeller beyond design speed?

💡 Explanation

Cavitation increases with propeller speed because Bernoulli's principle dictates reduced pressure; vapor bubbles then collapse violently near the surface causing erosion, therefore cavitation raises pitting risk, rather than reduced friction or higher efficiency.
