Troubleshooting & FAQ
How do I know if this carb kit fits my engine?
This kit is for Yamaha 40HP and 50HP 2-stroke outboards from 1984–1988. The most reliable way to confirm fitment is to check your engine's model against the compatibility table. Also, verify that your OEM carburetor repair kit part number is 6H4-W0093-01-00 or the superseded 6H4-W0093-00-00.

Common symptoms include hard starting, rough idling, stalling at low speeds, engine hesitation on acceleration, black smoke (running rich), or visible fuel leaks. Reduced performance and poor fuel economy are also key indicators.
