Troubleshooting & FAQ
How do I know if this washer fits my engine?
This washer is designed for specific Yamaha 25-30HP and some Parsun models. Please verify your engine model against the compatibility list on this page. Comparing the part number 90209-24M03-00 to your service manual is the best way to confirm fitment.
What are the signs of a failing washer?
A worn or damaged washer may lead to fluid leaks, loose fittings, or improper alignment of components. If you notice leaks around the engine housing or hear unusual vibrations, inspect the relevant washers for wear or damage.
What is the difference between this and a standard washer?
This is a "special shape" washer, meaning it is engineered with specific dimensions and contours to fit a particular application within the engine. A standard flat washer will not work as a substitute.
Can I reuse my old washer?
It is not recommended to reuse washers, especially in critical engine applications. They are often single-use parts designed to deform slightly to create a perfect seal. Reusing an old washer may result in leaks or improper torque.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
