The impeller is the wear part inside the water pump housing that draws in raw water and circulates it through the engine's cooling passages, so a worn or cracked impeller is a common cause of overheating, reduced water flow, or a weak telltale stream. This impeller is molded from durable plastic in a white finish and is packaged one per unit for a single water pump service. It is designed to install into Sierra's 18-3256 Water Pump Kit when a full pump rebuild is being performed, but it can also be used on its own as a direct replacement for the original impeller if the rest of the pump housing and wear plate are still in good condition. Sierra states that this part meets or exceeds the specifications of the original equipment impeller it replaces. Because water pump impellers are fit-specific to a narrow range of engine models, confirm your outboard's exact model and horsepower against the fitment listed below before ordering, since a mismatched impeller will not seat correctly in the pump housing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
