Troubleshooting & FAQ
How do I know if this gasket fits my Yamaha outboard?
This gasket is designed for specific Yamaha 48HP and 55HP 2-stroke models produced between 1989 and 2000. To ensure a perfect match, please consult the 'Engine & Model Compatibility' table on this page and cross-reference your engine's model number and year.
What are the signs of a failed upper casing gasket?
A faulty upper casing gasket can lead to a variety of symptoms, including water in the engine cylinders, engine overheating, loss of compression, poor performance, or visible water/exhaust leaks from the seam between the power head and the drive shaft housing.
Should I use sealant with this gasket?
Generally, this gasket is designed to be installed dry without any additional sealants. Applying sealant can interfere with proper seating and torquing. Always follow the specific recommendations in your engine's service manual for the final word on sealants.
