Water Pump Impeller for Nissan/Tohatsu Outboard
Regular impeller replacement keeps your outboard’s cooling system operating in top form—having a spare can save the day.
Impellers are the heart of an engine’s cooling system and should be replaced annually. Sierra offers replacement impellers engineered to meet or exceed manufacturer’s specifications to provide boaters and technicians the confidence of a factory fit and function. Impellers can be quickly damaged if run through silty or sandy water or if the water supply is interrupted. Both situations can reduce water flow and cause the engine to overheat. We recommend taking along a spare for these unexpected failures.
