It is the genuine Waterway part, the same impeller the pump left the factory with.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the impeller does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe impeller is the only moving part in the wet end. It spins on the motor shaft and throws water outward, and everything the pump delivers at the returns comes from it. When the vanes wear thin, or fine debris packs into them, the pump keeps running at full speed while moving noticeably less water. Owners usually notice slow returns, a skimmer that will not pull, and a pump that takes longer to prime.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch the horsepower\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eImpellers are cut for a specific horsepower.
