27-64692 Rochester Carburetor Mounting Gasket Fits MerCruiser Model 140, Model 120

This Rochester carburetor mounting gasket is designed for the carburetor-to-manifold interface on matching MerCruiser and OMC marine engine applications. It provides the base seal needed when removing a Rochester carburetor or servicing the intake manifold mounting surface. This listing is for the individual mounting gasket rather than a complete carburetor rebuild kit or full manifold gasket kit. Always verify your installed carburetor type—such as Rochester versus MerCarb—and match the original gasket reference number before ordering.

Free shipping on all orders. Lifetime warranty for product quality defects. Normal wear and tear excluded.

Fitment

The 27-64692 Rochester Carburetor Mounting Gasket from XR Marine fits MerCruiser Model 140 (including 140 HP Inline 4 GM 181 CID Wet Joint configurations and shared 153/181 CID Wet Joint configurations), MerCruiser MODEL 120 (shared 153/181 CID Inline 4 Wet Joint configurations), and documented MerCruiser and OMC 120 HP and 140 HP (2.5 L and 3.2 L) marine engines equipped with a Rochester carburetor at the carburetor-to-manifold interface in the applications listed below.

Compare your engine identification plate with the individual model-year entries below, verify the complete OEM gasket reference number, and confirm all carburetor and manifold configuration notes. Horsepower or engine displacement alone cannot confirm fitment—in documented MerCruiser catalogs, the Rochester carburetor base uses OEM reference 27-64692 while the MerCarb base uses 27-807982-1.

Installation Guide

General installation overview. Follow the service manual for your exact engine and carburetor configuration. Fuel-system work requires the appropriate skills and precautions.

  1. Verify identification and prepare the work area: Confirm that the engine is shut off and cool, isolate the fuel supply and ignition system per your service manual, and ensure the workspace is well-ventilated and free of ignition sources. Before disconnecting linkages or fuel lines, check that your engine uses a Rochester carburetor and compare the new mounting gasket (27-64692) against your parts diagram.
  2. Inspect the mounting surfaces and compare the gasket profile: Note the routing of all throttle, choke, and fuel connections, then remove the carburetor according to the factory service manual. Clean the carburetor base flange and the intake manifold mounting pad thoroughly without gouging the metal, and compare the old base gasket directly against the replacement gasket to verify bolt-hole alignment and bore cutouts.
  3. Install the gasket, reassemble, and check for leaks: Position the mounting gasket at the carburetor-to-manifold interface in the orientation specified by your manual, reinstall the carburetor, and tighten the mounting fasteners evenly to factory specifications. Reconnect all lines and linkages, verify smooth throttle and choke operation without binding, restore fuel pressure to check for leaks, and perform an engine run test only with proper cooling water supplied.

Before You Order

A careful fitment check helps you choose the right part the first time.

  • Match the full engine model designation on the identification plate.
  • Check the individual year entry and any serial-number or version restrictions.
  • Compare the complete OEM reference number, including its suffix. Horsepower or appearance alone is not enough.
  • Confirm the package contents and the quantity needed for your repair.
  • Identify the installed carburetor brand and type on your engine—in documented MerCruiser parts catalogs, the Rochester carburetor base uses gasket 27-64692, whereas the MerCarb base is listed separately as 27-807982-1.
  • Verify whether your repair only requires this carburetor-to-manifold base gasket or a complete carburetor rebuild / exhaust manifold gasket repair kit.

Frequently Asked Questions

Answers to common questions about this product and its application.

How do I know if my MerCruiser 120 or 140 uses gasket 27-64692 instead of a MerCarb base gasket?

Do not select a carburetor base gasket by engine horsepower or displacement alone. Check the carburetor installed on your engine and look up the base gasket in your engine parts catalog. In the documented MerCruiser catalog, OEM reference 27-64692 is listed for the Rochester carburetor base-gasket position, while 27-807982-1 is listed separately for the MerCarb base-gasket position.

Is this product a complete carburetor rebuild kit or manifold gasket kit?

No. This product is the individual Rochester carburetor mounting gasket for the carburetor-to-manifold interface. While this gasket may also be included as a component inside certain MerCruiser Wet Joint exhaust manifold gasket repair kits, this listing supplies the mounting gasket rather than a complete carburetor or manifold kit.

What engine configurations are documented for the 1968–1995 MerCruiser Model 120 and Model 140 entries?

For 1968–1982 MerCruiser Model 140 (140 HP), the documented applications specify an Inline 4, GM 181 CID, 4-cylinder Wet Joint configuration using Rochester base gasket reference 27-64692. For 1982–1995 MerCruiser MODEL 120 and Model 140 entries, the catalog lists Inline 4, 4-cylinder Wet Joint applications under a shared 153/181 CID group (Ref. 8, OEM 27-64692). Always verify your specific engine and carburetor setup before ordering.

Which OEM and aftermarket part numbers are referenced for this mounting gasket?

Documented reference numbers include MerCruiser 27-64692, 27-32910, 64692, and 32910; OMC 315055; additional reference numbers 0315055, 0508563, 0508579, 0777923, 508563, 508579, 777923, and 47-315055; as well as aftermarket references Sierra 18-0356, 18-0937, 18-0937-9, GLM 31660, and RECMAR REC27-64692. Always compare the full reference number and confirm your carburetor version.

Where is this gasket installed during service?

It is installed at the carburetor-to-manifold mounting interface (carburetor base) when removing or reinstalling a matching Rochester carburetor or servicing the intake manifold.

Does this gasket include free shipping and warranty coverage?

Yes. XR Marine provides free shipping on all orders with no minimum order value, along with a lifetime warranty covering product quality defects (normal wear and tear excluded).
