Troubleshooting & FAQ
How do I know if this carb rebuild kit will fit my engine?
This kit is designed for specific Yamaha and Mercury 40 HP 2-stroke twin-carburetor models. Please check the "Engine & Model Compatibility" table and verify your engine's model number and year. Comparing the parts in the photos to your existing carburetor components is also a reliable way to confirm fitment.
The kit lists two part numbers for the needle valve. Which one is correct?
The kit includes needle valves that are equivalent to both Yamaha OEM part numbers 6H3-14590-01-00 and 6H3-14590-02-00. Sources indicate these are often interchangeable or that one supersedes the other. The included valve is designed to function correctly in place of either original part for the listed applications.
My engine has trouble idling or bogs down on acceleration. Will this kit solve it?
A faulty or clogged carburetor is a common cause of poor idling, hesitation, and stalling. This rebuild kit replaces the most common wear items like gaskets, seals, and needle valves that can cause these issues. While it often resolves these problems, other factors like fuel quality, spark plugs, or timing could also be involved.
How often should a marine carburetor be rebuilt?
There is no fixed interval, as it depends on usage, fuel quality, and storage conditions (especially with ethanol-blended fuels). A rebuild is typically needed when performance degrades or every 3–5 years for preventative maintenance.
Will this kit work for a single carburetor engine?
No, this kit is specifically designed for twin (dual) carburetor 40 HP outboard engines. It contains two sets of the necessary components to rebuild both carburetors simultaneously.
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.
Shipping speed & cost?
