66T-14301-01-00 Carburetor Fits Yamaha Outboard T40, T30
This XR Marine product is a replacement carburetor for the listed Yamaha T40 and T30 outboard applications. It is a complete carburetor unit rather than a carburetor repair kit.
When selecting a replacement carburetor, verify the full engine model designation on your motor and match the complete OEM part number, including all suffixes. Do not rely on general horsepower figures or partial prefix numbers alone when comparing versions.

OEM & Part Number References
Use the complete reference number, including its suffix, when comparing parts. Reference numbers do not confirm that every version is interchangeable.
What's Included
Check the supplied components before planning your repair.
- Carburetor (included; confirm the exact supplied quantity and any required mounting gaskets before ordering).
Installation Guide
General installation overview. Follow the service manual for your exact engine and carburetor configuration. Fuel-system work requires the appropriate skills and precautions.
- Verify Part Compatibility: Compare the new carburetor against your existing unit and check the full engine model designation and complete OEM reference number before starting work.
- Prepare the Engine Safely: Shut off the engine, allow it to cool completely, disconnect the battery or ignition source, shut off the fuel supply, and work in a well-ventilated area away from open flames or sparks.
- Document Linkages and Hoses: Note or photograph the routing and attachment points of all fuel lines, vent hoses, choke mechanisms, and throttle linkages before disconnection.
- Remove the Existing Carburetor: Drain residual fuel from the carburetor bowl into an approved container, disconnect the hoses and linkages, and unbolt the carburetor according to your service manual.
- Inspect Mounting Surfaces: Clean the intake manifold flange carefully, ensuring no old gasket material or debris enters the intake port, and verify that all mounting surfaces and passages align properly.
- Install the Replacement Carburetor: Position the carburetor on the mounting flange, tighten the fasteners evenly per your service manual procedures, and reconnect the throttle and choke linkages.
- Check Linkage Operation and Fuel Tightness: Verify smooth, unrestricted movement of the throttle and choke from full close to full open, reconnect the fuel line securely, and prime the fuel system while inspecting for any fuel seepage.
- Test Run with Cooling Water: Supply proper cooling water to the outboard before starting, run the engine, and perform any required idle or synchronization adjustments specified in your service manual. Shut down immediately if leaks or binding occur.
Before You Order
A careful fitment check helps you choose the right part the first time.
- Match the full engine model designation on the identification plate.
- Verify your specific model code and any serial-number or version requirements in your engine parts catalog.
- Compare the complete OEM reference number, including its suffix. Horsepower or appearance alone is not enough.
- Confirm the package contents and the quantity needed for your repair.
- Do not treat 66T-14301, 66T-14301-02, and 66T-14301-02-00 as automatically interchangeable identifiers without confirming the exact version required for your engine.
- Note that this listing is for a complete carburetor unit, not a carburetor rebuild or repair kit.

Contact XR Marine About WarrantyFrequently Asked Questions
Answers to common questions about this product and its application.
Is this product a complete carburetor or a carburetor repair kit?
This product is a replacement carburetor unit for the listed Yamaha outboard applications. It is not a carburetor repair or rebuild kit.
Which Yamaha outboard models are listed for this carburetor?
This carburetor is listed for Yamaha Outboard T40 and T30 applications. Because individual horsepower allocations between the T40 and T30 models are not separately established by the source data, you must verify your full engine model designation and complete OEM part number rather than relying on horsepower alone.
Why do the suffixes on 66T-14301 part numbers matter when checking fitment?
Yamaha carburetor part numbers use suffixes (such as -01-00, -02-00, -03-00, -12, -22, or -40) to identify specific versions. Do not treat partial numbers like 66T-14301, 66T-14301-02, and 66T-14301-02-00 as automatically interchangeable without confirming the exact version required by your engine.
Does this carburetor correspond to Sierra 18-34605?
Yes, Sierra 18-34605 is listed as an aftermarket reference number associated with this carburetor. Always cross-check the complete Yamaha OEM part number for your specific motor before ordering.
Will I need to adjust the carburetor after installation?
During installation, you should inspect throttle and choke linkage travel and follow the factory service manual for your exact Yamaha engine to verify idle speed, synchronization, and fuel-system adjustments while running the motor with a proper cooling water supply.
What shipping and warranty coverage apply to this order?
XR Marine offers free shipping on all orders with no minimum order value. The product is backed by a lifetime warranty covering product quality defects, with normal wear and tear excluded.
