Installation Notes

  1. Disconnect the battery and ensure the engine is cool. Relieve any pressure from the fuel system.

  3. Disassemble the carburetor on a clean workbench, taking note of the location of all parts.
  4. Clean all metal components with a quality carburetor cleaner. Do not use cleaner on rubber or non-metallic parts.
  5. Replace old gaskets, seals, needles, and other wear items with the new components from the kit.
  6. Reassemble the carburetor, ensuring all parts are correctly installed and screws are tightened to the proper torque.
  7. Reinstall the carburetor onto the engine, reconnecting all lines and linkages.
  8. Start the engine and check for leaks. Adjust the idle speed and mixture screws as needed for smooth operation.

Troubleshooting & FAQ

Which specific carburetors does this kit fit?

This kit is exclusively for Mercruiser engines equipped with a Rochester 2-barrel (2BBL) carburetor. It will not fit Holley, Carter, or Rochester 4-barrel (Quadrajet) models.

What are the signs that my carburetor needs to be rebuilt?

Common symptoms include difficulty starting the engine, a rough or inconsistent idle, stalling, hesitation upon acceleration, black smoke from the exhaust, and decreased fuel economy. These issues often point to clogged passages, failed gaskets, or an incorrect fuel/air mixture that a rebuild can correct.

Is this kit compatible with a GM 305 V8 engine?

Yes, this repair kit is designed for the marine versions of the GM 305 V8 engine as used by Mercruiser in the models listed in the compatibility table, provided they use the specified Rochester 2BBL aarburetor.

Do I need special tools for the installation?

Standard hand tools such as wrenches, screwdrivers, and pliers are required. A carburetor cleaning solvent and compressed air are highly recommended for cleaning internal passages. A torque wrench can be useful for reassembly to manufacturer specifications.

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.
