Answer / Avinash Kumar Munda

Propellers can be damaged by various factors, including:
1. Collision with objects: Contact with submerged debris, rocks, or other vessels can cause serious damage to a propeller.
2. Overload: Operating the engine at too high of a load for extended periods can cause the propeller to overheat and warp, reducing its efficiency.
3. Cavitation: The formation of vapor bubbles in the propeller blade's high-pressure areas can lead to erosion and damage as the bubbles collapse under pressure.
4. Corrosion: Exposure to saltwater or other corrosive substances can cause the propeller blades to rust and weaken over time.
