Impellers cool your boat's engine by pumping cold water into it while it's running. When you have a broken impeller, you can have a lot of trouble. Water cannot be pumped inside due to a faulty impeller, causing the engine to overheat. The boat engine overheats when you accelerate, impeller vanes lose flexibility, and physical wear and tear like cracks in the impeller vane roots and melted or worn vanes are all signs of a faulty boat impeller.
