Troubleshooting & FAQ
How do I know if this gasket fits my specific engine model?
The most reliable method is to check your engine's model number and year against the compatibility table provided on this page. You can also compare your old gasket's part number to the cross-reference numbers listed in our Part Number Matrix.
What are the common signs of a failed cylinder head gasket?
Symptoms of a blown head gasket include engine overheating, loss of power, white smoke from the exhaust (burning coolant), milky or foamy oil, and bubbling in the radiator or coolant reservoir. These indicate a breach between the combustion chamber and coolant passages.
What is the difference between Yamaha part numbers 6E5-11181-A0-00, A1, and A2?
This is a supersession chain. 6E5-11181-A0-00 was the original part, which was later improved and replaced by ...A1-00, and then again by ...A2-00. Each new version is a direct, improved replacement for the previous ones. Our gasket is made to the latest ...A2-00 specification.
Is any special sealant required during installation?
Generally, modern head gaskets are designed to be installed dry without any additional sealants. Applying sealant can interfere with the gasket's ability to create a proper seal. Always follow the specific instructions in your outboard's official service manual.
How can I confirm my old part number?
The part number is often stamped or printed directly on the gasket. If it's unreadable, you can find the correct OEM part number by looking up your engine's model and serial number in an online parts catalog from a reputable source like Yamaha.
What does "For Cylinder & Crankcase 2" mean?
In engine diagrams, parts are often located with reference to larger assemblies. This note means the gasket is used in the assembly labeled "Cylinder & Crankcase 2" or "Repair Kit 1" in the official Yamaha service diagrams, helping mechanics pinpoint its exact location.
OEM vs. Aftermarket?
