Troubleshooting & FAQ
Q: How do I confirm this carburetor kit fits my specific outboard?
A: Cross-reference your engine's model and year with the compatibility table above, and verify your OEM carburetor part number is 6G1-W0093-00-00. If you have a Yamaha, consult the serial number guide or parts diagrams linked in the Compatible Engine Models section.
Q: What are the signs that my carburetor needs rebuilding?
A: Common symptoms include hard starting, rough idle, poor acceleration, fuel leaks around the carburetor, or the engine flooding. If your outboard has been sitting for an extended period, old fuel can gum up internal passages and damage seals.
Q: How often should I replace carburetor gaskets and seals?
A: Rebuild intervals depend on usage and fuel quality, but most mechanics recommend inspecting carburetor components every 2–3 years or 200–300 hours of operation. Always rebuild if you notice fuel leaks or performance issues.
Q: Can I reuse the old float or needle valve?
A: Reusing worn components defeats the purpose of a rebuild. The float may have absorbed fuel (causing incorrect fuel levels), and a worn needle valve will not seal properly, leading to flooding and poor performance.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
