Installation Notes

Troubleshooting & FAQ
How do I know if this gasket fits my specific engine?
This gasket is designed for Yamaha and Mercury/Mariner 70-115HP 4-stroke models from approximately 1999–2006. The most reliable way to confirm fitment is to check the "Engine & Model Compatibility" table and cross-reference your exact engine model and OEM part number (such as 67F-11181-03-00 or 27-8041151).
What are the common signs of a failed cylinder head gasket?
Symptoms of a blown head gasket can include persistent engine overheating, a noticeable loss of power, white-colored smoke from the exhaust (burning coolant), or discovering water in the engine oil, which gives it a milky or foamy appearance.
Is any sealant required for installation?
Modern head gaskets, including this one, are typically installed dry without any additional sealants. Applying sealant can interfere with the seal. Always consult your engine's official service manual for the most accurate, model-specific instructions.
Why are there multiple Yamaha part numbers listed as replacements?
The part numbers 67F-11181-00-00, 67F-11181-01-00, and 67F-11181-02-00 are earlier versions of this part that have been superseded by the manufacturer. This gasket (equivalent to 67F-11181-03-00) is the current, direct replacement for all of those previous numbers.

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.
