Installation Notes

Ensure the engine is off and cool, and disconnect the battery as a safety precaution.
Turn off the fuel supply and carefully drain any remaining fuel from the carburetor bowl.
Remove the screws securing the float chamber bowl and detach it from the carburetor body.
Take out the old gasket and thoroughly clean both mating surfaces, removing any old sealant or debris.
Position the new gasket correctly on the carburetor body.
Re-attach the float chamber bowl, tightening the screws in a star or crisscross pattern to ensure even pressure. Do not overtighten.
Turn the fuel supply back on and check for any leaks around the bowl before reconnecting the battery and starting the engine.

Troubleshooting & FAQ

How do I know if this gasket will fit my Yamaha outboard?

This gasket is designed for a range of 40-90 HP 2-stroke Yamaha models. The best way to confirm fitment is by matching your existing part number to the replacement number 676-14984-00-00. Always visually compare the new gasket to your old one before installation.

What are the signs of a failing float chamber gasket?

Common signs include visible fuel leakage or weeping around the carburetor bowl, a strong smell of gasoline, poor engine idling, stalling, or difficulty starting. These symptoms indicate the seal is compromised and should be replaced.

Is any sealant required when installing this gasket?

No, this gasket is designed to create a seal on its own. Applying sealant can interfere with proper seating and may even cause damage if it gets into the carburetor's internal passages. Simply ensure both mating surfaces are clean and dry.

How often should the float chamber gasket be replaced?

It is good practice to replace the float chamber gasket any time the carburetor bowl is removed for service, cleaning, or jetting. Gaskets can compress, dry out, and crack over time, so replacing them proactively prevents future leaks.
