Troubleshooting & FAQ
How do I know if this gasket fits my Yamaha outboard?
This gasket is designed for Yamaha HPDI 6-cylinder 2.6L engines (150, 175, and 200HP) from specific model years. Cross-reference your engine's model number and year with our compatibility table, and also check that your old part's number matches one of the equivalents in the Part Number Matrix.
What are common signs of a failing cylinder head gasket?
A bad head gasket can cause several issues, including engine overheating, loss of power, white smoke from the exhaust (coolant burning), milky or frothy engine oil (coolant mixing with oil), or visible external coolant/oil leaks from the seam between the cylinder head and the block.
Can a bad head gasket cause my engine to overheat?
Yes. A common failure mode is for the gasket to leak between a coolant passage and a combustion chamber. This can push hot combustion gases into the cooling system, displacing coolant and causing the engine to overheat quickly.
Do I need to use a sealant with this gasket?
Generally, modern head gaskets like this one are designed to be installed dry, without any additional sealants. Applying sealants can interfere with the gasket's ability to create a proper seal and may cause premature failure. Always follow the specific instructions in your engine's service manual.
How often should a cylinder head gasket be replaced?
A cylinder head gasket is not a routine maintenance item. It is designed to last the life of the engine and should only be replaced if it has failed. Its lifespan can be shortened by severe overheating or improper installation.
What's the difference between this and an OEM part?
This is a high-quality aftermarket replacement, not an original Yamaha part. It is engineered to meet or exceed OEM specifications for fit, material quality, and performance. All parts are manufactured in an ISO 9002 certified facility and undergo batch inspection to ensure reliability and consistency.
What are your shipping speeds and costs?
We ship worldwide. Standard shipping is free for most orders, with a typical transit time of 5–15 days. Expedited shipping options may be available at checkout for an additional cost depending on your location.
What is the warranty and return policy?
This part is covered by a 1-year warranty against manufacturing defects under normal marine use. If you encounter an issue, please contact our support team with your order details. We accept returns for unused items in their original packaging within our standard return window. Please see our policy page for full details.
