Troubleshooting & FAQ
Will this gasket fit the starboard (right) side of the engine?
No, this gasket is designed specifically for the port (left) side. The starboard side requires a different part (OEM #336389).
What are the signs of a bad intake manifold gasket?
Common symptoms include a rough or high idle, engine misfires, poor acceleration, vacuum leak codes (Check Engine Light), or coolant/oil leaks near the intake manifold.
Is this gasket suitable for use with ethanol-blended fuels?
Yes. It is made from Viton, a high-quality fluoroelastomer known for its excellent resistance to gasoline, ethanol (E10/E15), oil, and high temperatures, making it ideal for marine applications.
Should I use sealant or adhesive with this gasket?
This gasket is typically designed to be installed dry. Applying sealants can interfere with its ability to create a proper seal. Always follow the procedures in your engine’s official service manual.
How can I confirm this is the right part for my engine?
Cross-reference your original part number with those listed in the Part Number Matrix. Additionally, check your engine model, HP, and year against the Engine & Model Compatibility table.
