Troubleshooting & FAQ

Q: How do I confirm this carburetor fits my Mercury engine?

A: Check your engine's model and year against the "Compatible Engine Models" table. You can also use our Mercury Serial Number Guide to find your model information and verify the OEM part number matches one of the cross-references listed.

Q: What are the signs my old carburetor needs replacing?

A: Common symptoms include difficulty starting, rough idling, engine stalling at low speeds, poor acceleration, or black smoke from the exhaust, all of which can indicate a fuel and air mixture problem.

Q: Is this a direct replacement for a Johnson/Evinrude carburetor?

A: While designed primarily for Mercury outboards, this carburetor is cross-compatible with specific Johnson/Evinrude 9.9HP and 15HP models from 1993-2002 that use equivalent part numbers like 0438562. Please verify your current part number before ordering.
