Abstract
This disclosure relates a water pump, a system for cooling internal combustion engine components including a water pump, and a method for operating an internal combustion engine including a water pump. The water pump, 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 dispensing fluid from a reservoir to the pump's impeller chamber. The fluid enters the chamber via a controllable flow path and interacts with the impeller and chamber walls to cool and lubricate the impeller.
