Product Details
This aftermarket carburetor is intended for Yamaha 40X and E40X 2-stroke outboard applications. The Yamaha carburetor catalog identifies OEM reference 66T-14301-60 with the 40X and E40X model families.
The company product record lists this carburetor under Yamaha Outboard and also identifies Yamaha references 66T-14301-00 and 66T-14301-70. Because carburetor suffixes can vary by engine version, compare the complete reference, model designation, linkage arrangement, mounting pattern, and photographs with the original component before ordering.
- Replacement carburetor for selected Yamaha 2-stroke outboard applications.
- Designed as a bolt-on replacement where the mounting pattern and connections match.
- Suitable for gasoline-fueled outboard engines.
- Supplied as one carburetor, not as a multi-component kit.

Troubleshooting & FAQ
How do I confirm fitment?
Check that your engine is a Yamaha 40X or E40X 2-stroke model and compare the complete carburetor reference, mounting flange, fuel inlet, control linkages, and overall appearance with the replacement. Model family alone is not sufficient when suffixes or production versions differ.
Is this an OEM Yamaha carburetor?
No. This listing is for an aftermarket replacement carburetor. The Yamaha references are provided for identification and application matching only.
Does the package include a gasket or adjustment parts?
The package is one carburetor. A gasket, hoses, linkages, adjustment tools, or other accessories are not confirmed as included.
Will this fit every Yamaha 40 HP outboard?
No. The documented application is limited to the listed 40X and E40X 2-stroke model families. Verify the exact engine model and original part before ordering.
What symptoms may indicate a worn carburetor?
Hard starting, unstable idle, stalling, hesitation, poor acceleration, fuel leakage, or an inability to maintain proper engine speed can indicate a carburetion problem. These symptoms can also have other causes, so inspect the complete fuel and ignition systems before replacing parts.
Safety & Important Information
- Gasoline is flammable. Work in a well-ventilated area away from sparks, flames, and ignition sources.
- Do not operate the engine if fuel leaks are present.
- Use the correct service-manual procedures and torque specifications for your engine.
- Professional marine-mechanic installation is recommended, especially when fuel-system adjustments are required.
- Always verify exact model, year or serial range where applicable, and part configuration before ordering.
