6L2-14301-00 Upper Carburetor Without Fuel Pump Fits Yamaha Outboard (20 HP / 25 HP)

This XR Marine replacement is the upper carburetor assembly without a fuel pump, designed for matching Yamaha 20 HP and 25 HP 2-cylinder, 2-stroke outboard engines. It is intended for replacing the upper, non-fuel-pump carburetor unit on multi-carburetor setups that use OEM reference 6L2-14301-00, 6L2-14301-01, or 6L2-14301-11-00.

Please verify the mounting position and fuel-pump configuration before ordering: this upper carburetor does not include a fuel pump and is sold separately from the lower fuel-pump-equipped carburetor (referenced as 6L2-14302-00). It is a single upper carburetor assembly, not an upper-and-lower carburetor set.

Fitment

The 6L2-14301-00 Upper Carburetor Without Fuel Pump from XR Marine fits Yamaha Outboard 20 HP and 25 HP 2-Stroke outboards when configured as a 2-cylinder engine using an upper carburetor without a fuel pump, as detailed in the applications listed below.

Match your engine identification plate and existing carburetor markings against the entries below, compare the complete OEM reference number including its suffix, and verify every configuration requirement. Horsepower alone cannot confirm fitment—you must verify that your 2-cylinder, 2-stroke engine requires the upper non-fuel-pump carburetor rather than the lower fuel-pump-equipped unit.

• Brand: Yamaha Outboard | Power: 20 HP | Stroke: 2-Stroke | Restriction: Cylinder count: 2; Carburetor position: Upper; Fuel pump configuration: Without fuel pump. Match the original carburetor reference and position.

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.

1. Verify Position and Part Reference: Before beginning disassembly, confirm that you are servicing the upper carburetor position without a fuel pump and match your existing part against OEM reference 6L2-14301-00, 6L2-14301-01, or 6L2-14301-11-00.
2. Prepare the Engine Safely: Shut off the engine, allow it to cool completely, disconnect the fuel supply and ignition system according to your Yamaha service manual, and work in a well-ventilated area away from any open flames or ignition sources.
3. Document Linkages and Routing: Take clear photos or notes of the fuel hoses, throttle linkage, choke linkage, and synchronization rod connections between the upper and lower carburetors to ensure accurate reassembly.
4. Remove the Original Upper Carburetor: Carefully detach the intake cover, fuel lines, and linkage connections, then unbolt the original upper carburetor while catching any residual fuel in an approved container.
5. Compare Assemblies Side by Side: Place the removed upper carburetor next to the new XR Marine unit to inspect flange geometry, throttle and choke lever orientations, fuel inlet position, and confirm that no fuel pump boss is required in this position.
6. Mount and Reconnect: Clean the intake manifold mating surface, install the upper carburetor using serviceable gaskets and hardware per your service manual, and reconnect the fuel hose and linkages without binding.
7. Synchronize and Adjust per Manual: On 2-cylinder dual-carburetor engines, check throttle plate synchronization between the upper and lower carburetors and perform idle mixture or speed adjustments strictly following your Yamaha service manual specifications.
8. Leak Test and Water-Supplied Run Check: Prime the fuel system and inspect all connections for fuel leaks before starting. Run the outboard only with a proper cooling water supply connected, verify smooth throttle return, and shut down immediately if any fuel leak, linkage sticking, or abnormal running occurs.

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 and confirm your outboard is a 2-cylinder, 2-stroke Yamaha 20 HP or 25 HP configuration.
• Check the engine parts diagram for your exact model and serial number, and verify all position and fuel-pump restrictions listed on this page.
• 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.
• Verify upper vs. lower position: this product (6L2-14301-00) is the upper carburetor without a fuel pump. It does not replace the lower fuel-pump-equipped carburetor (6L2-14302-00), which is sold separately.
