Troubleshooting & FAQ
What are the signs of a worn thrust washer?
Symptoms of a failing thrust washer include excessive propeller vibration, a distinct rattling or grinding noise from the lower unit while in gear, and visible signs of scoring, cracking, or deformation on the washer itself upon inspection.
Will this fit other Parsun or Yamaha horsepower models?
This part is specifically designed for Parsun/Yamaha 4-5HP 4-stroke models. Using it on other models is not recommended unless your service manual explicitly lists part numbers PAF4-03000026 or 90201-08M54 as compatible.
How often should this part be replaced?
Thrust washers do not have a fixed replacement interval. They should be inspected for wear or damage whenever the propeller is removed for service. Replace it if you notice any scoring, warping, or significant thinning.
