More about this item

EMP 46-46221 Water Pump Kits

Higher-horsepower outboards work harder, run hotter, and demand more from every system on the engine, including the water pump. On a Yamaha in the 150 to 250 horsepower range, the water pump is moving a significant volume of coolant to keep combustion temperatures in check, and a worn impeller that cannot keep up with that demand will let the engine temperature climb faster than you want it to. Keeping the water pump in good shape on a big outboard is not optional maintenance, it is the kind of thing that protects a serious investment.

The EMP 46-46221 Water Pump Kit includes the housing along with the impeller and internal components needed for a complete pump service. Including the housing in the kit is the right call because a worn or distorted housing reduces the impeller's efficiency even when the impeller itself is new. Replacing both together ensures the pump performs the way it should from the first run after service.

This kit fits Yamaha outboards in the 150 to 250 horsepower range and is a direct replacement for Yamaha part numbers 61A-W0078-A1-00 and 6N6-W0078-02-00. If you are cross-referencing from either of those numbers, you are in the right place. EMP builds this kit to OEM specifications, so every component is dimensionally correct and made from materials suited for continuous marine use.

Water pump service is generally recommended every 100 hours of operation or every two to three years, whichever comes first. If you are pulling the lower unit for any reason, this is the right time to take care of it. The impeller does not announce when it is about to fail, so staying ahead of the service interval is always the smarter play on a high-output engine.
