Troubleshooting & FAQ
How do I confirm this washer plate fits my specific Yamaha engine?
The best method is to verify the part number 90201-23M01-00 against the parts list or diagram in your outboard motor's official service manual. Since this component is used in many models, matching the part number is crucial for guaranteeing a correct fit.
What are the signs of a faulty washer plate?
Common indicators that a washer plate needs replacement include visible signs of cracking, heavy corrosion, warping, or if it is completely missing. A failed washer can lead to loose connections, rattling noises, and improper component alignment.
Can I reuse my old washer plate?
It is not recommended. Washer plates, especially in a marine environment, are subject to stress, compression, and corrosion. For safety and reliability, always use a new, specified part like 90201-23M01-00 when reassembling components.
What is the function of this part?
A washer plate serves to distribute the pressure of a nut or bolt evenly over a larger surface area, preventing damage to the component being fastened. It also helps to prevent a bolt or nut from loosening due to vibration.
