Troubleshooting & FAQ
How do I know if this gasket will fit my Yamaha outboard?
This gasket is specifically designed for Yamaha F225, F250, and F300 4.2L V6 4-stroke models from 2010 through 2017. Please verify your engine model and year fall within this range before ordering.
What are the signs of a failing water pump gasket?
Common symptoms include the engine overheating at idle or low speeds, a weak or inconsistent "telltale" water stream, or visible water leaking from the seam where the water pump housing meets the lower unit.
When should I replace the water pump gasket?
It is best practice to replace the entire water pump kit, including this gasket and the impeller, every 100-200 operating hours or every 1-2 years, regardless of visible wear, to ensure cooling system reliability.
Is this gasket difficult to install?
Installation requires removing the lower unit, which can be a complex and heavy job. While it can be done by a mechanically inclined owner with the right tools, we recommend professional installation to prevent damage and ensure a correct seal.
