Installation Notes

Disconnect the battery and safely detach the fuel line.
Remove the carburetor from the engine, noting all linkage and hose connections.
Carefully disassemble the carburetor on a clean workbench to access the float bowl and float assembly.
Remove the pin holding the float to extract the old needle and then unscrew the seat.
Thoroughly clean the float bowl and all carburetor passages with a dedicated carburetor cleaner.
Install the new seat and needle, ensuring the needle is correctly attached to the float tab.
Reassemble the carburetor, verifying the float height is set to your engine’s service manual specifications.
Re-install the carburetor onto the engine, reconnect all lines and linkages, and test for leaks and proper idle before operation.

Troubleshooting & FAQ

How do I know if this needle and seat kit fits my engine?

This kit is for specific Mercury/Mariner V6 2-stroke outboards (135-200HP). The most reliable way to confirm is by matching your engine's serial number to the ranges listed in the compatibility table.

What are the signs of a failing carburetor needle and seat?

Common symptoms include fuel leaking from the carburetor, the engine flooding, stalling at idle, or difficulty starting. An overflowing float bowl is a direct sign of a bad needle and seat that is failing to seal properly.

Can I just replace the needle and not the seat?

It is highly recommended to replace both the needle and the seat as a matched set. They are designed to wear together, and installing a new needle into a worn seat will likely result in a poor seal and continued leaking.

Is any adjustment needed after installation?

Yes. After installation, you must check and adjust the float level according to your engine's service manual specifications. A correct float height is critical for ensuring proper fuel delivery and preventing flooding or starvation.

Does this kit include the float or bowl gasket?

This kit contains only the carburetor needle and seat assembly. Floats, gaskets, and other carburetor components are sold separately. We recommend replacing the float bowl gasket at the same time.

What is the recommended replacement interval?

There is no fixed replacement interval. You should inspect the needle tip for damage or deformation during regular carburetor servicing and replace the set if you notice any signs of wear or are experiencing fuel leak symptoms.
