Product Details
This aftermarket carburetor repair kit is intended for select Yamaha, Tohatsu, and Nissan 2-stroke outboard carburetors. It helps renew common service components such as gaskets, seals, the float, needle valve, and related hardware when the existing carburetor body and jets remain serviceable.
The kit is associated with Yamaha reference number 6G1-W0093-00-00 and Tohatsu/Nissan reference number 369-87122-1. The same aftermarket reference is also listed against Mercury reference 11502M and Sierra reference 18-7765. Always compare the carburetor assembly, original part numbers, model code, year, and serial-number range before ordering.
- Aftermarket replacement for rebuilding a compatible carburetor.
- Helps address worn gaskets, seals, float components, and needle-valve-related fuel issues.
- For gasoline-fueled 2-stroke outboards only.
- Does not replace the complete carburetor assembly and does not change jet sizes.

Troubleshooting & FAQ
How do I confirm compatibility?
Match the engine brand, exact model code, horsepower, stroke, year, and serial-number range. Then compare the carburetor body, gasket shape, float, needle valve, and original reference number with the product information and photos.
What symptoms can indicate a carburetor rebuild is needed?
Common symptoms include hard starting, unstable idle, stalling, hesitation, poor acceleration, fuel leakage, or a fuel mixture problem caused by worn or contaminated service parts. These symptoms can also result from ignition, fuel-supply, compression, or adjustment faults.
Does this kit change jetting?
No. This is a repair kit, not a performance jet kit. It is intended to replace compatible service parts and does not change the calibrated jet sizes.
Can I use the kit on a modified engine?
Only if the replacement components match the carburetor and the engine's intended calibration. Modified engines may require different jetting or tuning that this repair kit does not provide.
Is this an OEM part?
No. This is an aftermarket replacement kit. The OEM and aftermarket numbers shown above are provided for application and cross-reference purposes.
Should I reuse old gaskets or O-rings?
No. Reuse can lead to air or fuel leaks. Replace worn or removed sealing components with the correct parts supplied for the compatible application.
Safety & Important Information
- Fuel is flammable. Work in a ventilated area and keep the product away from heat, sparks, and open flames.
- Confirm the exact model, year, serial number, carburetor version, and original part number before ordering.
- Do not install this kit if the carburetor body is damaged or if the supplied parts do not match the original components.
- Professional installation is recommended when carburetor adjustment, float height, or fuel-system diagnosis is required.
