**Why Replace Your Jet Pump Housing?**
The **Yamaha Stainless Steel Jet Pump Housing 78-412-01A** is designed for use within the Yamaha WaveRunner jet propulsion system.
During operation, the engine drives the impeller, which moves water through the jet pump to generate thrust and propel the watercraft forward.
The jet pump housing surrounds the impeller and forms an important part of the water flow path.
Over time, pump housings may experience wear or damage caused by debris, corrosion, cavitation-related wear or contact with the impeller.
A damaged housing can affect the clearance between the impeller and surrounding pump components, potentially contributing to reduced propulsion efficiency, increased cavitation or poor acceleration.
Replacing a worn or damaged housing with the correctly specified component can help restore the intended pump assembly condition.
The **Yamaha Stainless Steel Jet Pump Housing 78-412-01A** provides a stainless steel replacement option for compatible Yamaha WaveRunner models requiring OEM part number **6ET-51312-00-00**.
**Important Installation Information**
Before installing a replacement jet pump housing, inspect the impeller, shaft, bearings, seals and surrounding pump components for signs of wear or damage.
Correct fitment and impeller clearance are essential for proper jet pump operation.
Follow the manufacturer’s recommended installation and servicing procedures.
