Abstract:
This disclosure relates a water pump control system for an internal combustion engine, and a method for operating an internal combustion engine including a clutch-controlled water pump. The water pump control system and method provide protection of the pump impeller during dry pump operation, such as when a watercraft engine is started while the watercraft is out of water, by turning off the clutch-controlled pump when no water is detected at the inlet of the water pump.
