Installation Notes

A quantity of three gaskets is required for a complete engine service.

  1. Ensure the engine is off and cool to the touch. Disconnect the battery for safety.
  2. Remove the engine cowling to access the carburetor and attenuator assembly.
  3. Carefully detach the carburetor(s) from the attenuator plate, taking note of any connected fuel lines, linkages, or hoses.
  4. Remove the old, compressed gaskets and thoroughly clean both mating surfaces. Ensure they are completely free of any old material, grease, or debris.
  5. Position the three new gaskets correctly between the attenuator and carburetors.
  6. Reassemble the components in reverse order, ensuring all bolts are tightened evenly to the manufacturer's specified torque.

Troubleshooting & FAQ

How do I confirm this gasket fits my Mercury engine?

Check the compatibility tables on this page against your engine's model, horsepower, and serial number range (listed as 'Years'). This part is a direct cross-reference for OEM part number 27-892211.

What are the signs of a failing attenuator gasket?

Common symptoms include a rough or unstable idle, fuel leaks around the carburetor base, whistling or vacuum leak sounds, and reduced engine performance due to an improper air-fuel mixture.

Why do I need three gaskets for this installation?

According to OEM service documentation for these 2.5L engines, the assembly between the attenuator plate and the carburetors requires three separate gaskets to ensure a proper seal. Please note this package contains one gasket.

When should this gasket be replaced?

This gasket should be replaced whenever the carburetor or attenuator is removed for service, cleaning, or rebuilding. It is a single-use part and should not be reused once compressed, as it will not provide a reliable seal.

OEM vs. Aftermarket?

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.
