Troubleshooting & FAQ
How do I know if this gasket fits my Yamaha outboard?
This gasket is for specific Yamaha 20, 25, and 30 HP 2-stroke models from 1984–1996. Review the "Engine & Model Compatibility" table and cross-reference your engine's model and year to confirm fitment. Do not rely on horsepower alone.
What are the symptoms of a failed water pump gasket?
Common signs include an engine that overheats at idle or low speeds, a weak or non-existent water stream from the "tell-tale" outlet, or visible water leaking from the seam between the lower unit and the upper casing.
How often should this gasket be replaced?
It is best practice to replace the water pump gasket whenever you service the impeller, typically every 100 hours of use or at least once per season, regardless of hours.
Can I reuse my old water pump gasket?
No. Gaskets are designed for a single use. They compress to create a seal and will not provide a reliable, leak-free seal if reused.
