6K8-51312-00-94 YAMAHA Waverunner Jet Pump Impeller Housing

Review YAMAHA Waverunner Jet Pump Impeller Housing Assembly for WR500 WR650 LX 1988–1992

The Yamaha 6K8-51312-00-94 is an essential component for the maintenance and optimal performance of Yamaha Waverunners model WR500 and WR650 LX from the years 1988 to 1992. More specifically, this part is the impeller housing for the jet pump.

The impeller housing is a critical piece of the water jet propulsion system, which creates thrust and maneuverability for these watercrafts. It encases and protects the impeller, the rotating component responsible for drawing water into the pump and forcing it out at high velocity to propel the Waverunner forward.

This particular Yamaha part is meticulously engineered for a perfect fit and function. The housing is made from durable, high-quality materials, ensuring it withstands the demands of continuous use in water. Its robust design allows it to handle the pressure and force generated by the impeller, while the smooth internal surface enables the impeller to operate efficiently.

The impeller housing also plays a crucial role in the cooling system of the watercraft. The water drawn into the pump passes through the housing, absorbing heat from the engine and jet pump components. This cooling process ensures the components operate within their optimal temperature range, extending their lifespan and overall performance.

When it comes to maintenance, the impeller housing is an essential component to keep an eye on. Over time, it can become worn or damaged, leading to decreased performance and potential safety risks. Regular inspections and timely replacement of the impeller housing can help prevent these issues and keep your Yamaha Waverunner in top condition.

In summary, the Yamaha 6K8-51312-00-94 is an essential impeller housing for Yamaha Waverunners model WR500 and WR650 LX from the years 1988 to 1992. Its robust design, critical role in the water jet propulsion system, and function in the cooling system make it an indispensable component for maintaining the performance and safety of your watercraft.

My wife and I still ride stand up skis to this day. I bought my first Kawasaki js550 stand-up jet ski back in 1988 and have been riding ever since. I end up covering partial cost of just about every package send out due to the high shipping these day. However, none of those experiences allowed me to work with my absolute favorite marine toy.

Excellent packaging. In 2012 my father and his two brothers decided to retire sell the business. Note 1: this unit is in good usable condition showing normal signs of age, usage and wear. Please reach out to me right away.
