Product Details
This aftermarket carburetor assembly is designed as a replacement for specific Yamaha 40 HP 2-stroke outboard applications. It is intended to restore proper fuel metering and reliable engine operation when the original carburetor is worn, damaged, corroded, or no longer serviceable.
The product is listed as replacing the Yamaha 6F6-14301-00 series and is also listed for select Parsun T36J and T40J 2-stroke outboards. Because carburetor fitment can vary by model, year, configuration, and serial-number range, compare the original part, mounting arrangement, linkages, and applicable reference number before ordering.
- Aftermarket replacement carburetor assembly.
- Designed for direct replacement where the application and mounting configuration match.

Troubleshooting and FAQ
How do I confirm that this carburetor will fit my engine?
Compare the original carburetor's reference number, mounting points, body shape, fuel connections, throttle or choke linkages, and overall dimensions. Also verify the complete engine model and serial-number information. A model name alone is not sufficient to confirm fitment.
What symptoms can indicate a failing carburetor?
Common symptoms include hard starting, rough idle, stalling, poor acceleration, inconsistent engine speed, excessive smoke, fuel overflow, and visible fuel leakage. These symptoms can also be caused by restricted fuel lines, incorrect adjustment, ignition problems, or other engine issues.
Does the carburetor require adjustment after installation?
Adjustment may be required after installation. Follow the engine manufacturer's service-manual procedure and specifications for idle speed, mixture, linkage, and synchronization. Do not rely solely on a factory setting from another engine.
Should the carburetor be cleaned before replacement?
Cleaning and inspection may resolve contamination-related problems, but replacement is appropriate when the carburetor is damaged, heavily corroded, has worn passages or threads, leaks after servicing, or cannot be adjusted correctly.
Is this an OEM part?
No. This listing is for an aftermarket replacement carburetor. The referenced Yamaha numbers are manufacturer reference numbers used for application comparison and do not mean that this product is manufactured by Yamaha.
What are the shipping and return terms?
Shipping availability, delivery estimates, warranty coverage, and return eligibility are determined by the current store policies shown at checkout. Contact support with your order details if the received part does not match the confirmed application.
Safety and Important Information
- Fuel-system work involves gasoline and vapors. Work only in a well-ventilated area away from ignition sources.
- Verify the engine model, configuration, reference number, images, mounting points, and connections before ordering.
- Do not operate the engine if fuel leaks are present.
- Follow the engine manufacturer's service manual for adjustment, testing, and safety procedures.
- Professional installation is recommended when the required procedures or adjustments are unfamiliar.
