The water pump impeller is essential for proper cooling of your boat engine to prevent over-heating.
When starting your engine always look at the stern for ripples in the water showing the pump is working correctly, and on outboards that the discharge is visible at the engine outlet.
After much usage, the paddles on the impeller may crack or even break loose at the base preventing the pump from cooling the engine.
Also, if the boat is not used for long periods, the paddles that are compressed may become permanently bent with a loss of pumping efficiency.
Mercury recommends replacing impellers every 300 hours or 3 years for most engines.
