Installation Notes
- Disconnect the battery and drain the engine's cooling system completely.
- Remove the engine cover, spark plug wires, and ignition coils from the cylinder head.
- Following the manufacturer's service manual, loosen the cylinder head bolts in the specified sequence to prevent head warpage.
- Carefully lift the cylinder head off the engine block.
- Remove the old head gasket and thoroughly clean any remaining gasket material from both the cylinder head and block surfaces. Use a plastic scraper to avoid gouging the metal.
- Position the new gasket correctly on the engine block; ensure it is not installed upside down or backward.
- Reinstall the cylinder head and torque the head bolts to the manufacturer's specified values using the correct tightening sequence.
- Reassemble all remaining components in the reverse order of removal.
Troubleshooting & FAQ
How do I know if my cylinder head gasket is failing?
Common signs of a bad head gasket include significant loss of power, engine overheating, white smoke from the exhaust, milky or frothy engine oil (indicating water a mix), or low compression in one or more cylinders.
Will this fit my 1985 70 HP Johnson motor?
No. This gasket is specified for 3-cylinder Johnson and Evinrude engines manufactured from 1986 to 2001. Using it on an incompatible model year may result in leaks or engine damage.
What is the correct torque specification for the head bolts?
Torque specifications and the tightening sequence are critical for a proper seal. This information is specific to your engine model and must be obtained from the official service manual for your engine. Incorrect torquing will lead to gasket failure.
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 sealant can interfere with the gasket's ability to seal properly. Always follow the instructions in your engine's service manual.
Is this gasket made of the same material as the OEM part?
This aftermarket gasket is manufactured with high-quality materials designed to meet or exceed OEM specifications for durability and sealing performance in a marine environment.
