Troubleshooting & FAQ

How do I know if this kit fits my engine?

This kit is designed for Mercury/Mariner 40-125HP 2-stroke outboards with WME-series carburetors. The surest way to confirm fitment is to check your carburetor for "WME" followed by a number, and cross-reference your engine's serial number against the compatibility table above.

How many carburetors does one kit service?

Each kit contains all the necessary components to rebuild one single carburetor. If your engine has multiple carburetors, you will need to purchase one kit for each.

What are the signs my carburetor needs to be rebuilt?

Common symptoms include difficulty starting, rough idling, stalling at low speeds, black smoke from the exhaust (running rich), or fuel leaks. A rebuild replaces deteriorated seals and clogged internal parts to restore proper fuel and air mixture.

Is it necessary to replace all parts in the kit?

Yes, for a complete and reliable rebuild, it is highly recommended to replace all gaskets, seals, and the needle-valve assembly provided in the kit. Skipping components can lead to incomplete repairs and persistent performance issues.

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?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns?

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.

Safety & Important Info

  • Verify images/specifications vs your original part. If anything differs—even if your model appears compatible—do not purchase.
  • This is an aftermarket replacement, not an OEM component.
  • Professional installation is recommended for safety and performance.
