62Y-W0093-11 Carburetor Repair Kit Fits Yamaha Outboard F40 (40 HP), F50 (50 HP)

This carburetor repair seal kit from XR Marine is designed for carburetor repair and seal servicing on specific Yamaha F40 (40 HP, 1999) and F50 (50 HP, 1995–2000) outboard engine applications. Rather than replacing the complete carburetor body, this service kit provides internal sealing and metering components including gaskets, a float assembly, a needle valve, throttle screws, an air adjusting screw, and O-rings. Because the F40 and F50 applications have distinct model-year limits, always match your full engine model designation, production year, and complete OEM reference number 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.

1. Preparation and Component Verification: Ensure the engine is shut off and cool, disconnect the ignition and fuel supply according to your service manual, and work in a well-ventilated area away from ignition sources. Document the routing of fuel lines and throttle linkages before removal, then lay out the supplied gaskets, float assembly, needle valve, screws, and O-rings to compare them directly against your existing carburetor parts.
2. Cleaning and Seal Replacement: Disassemble the carburetor following your Yamaha service manual procedures and clean all fuel passages and mating surfaces thoroughly. Replace only the components that match your specific carburetor configuration, verifying that the needle valve seats properly, the float assembly moves freely without binding, and all O-rings and gaskets align cleanly without blocking ports.
3. Reassembly and Leak Inspection: Reassemble the carburetor and set the air adjusting screw, throttle screws, and float settings strictly to the specifications in your engine service manual. Reinstall the carburetor, reconnect the linkages and fuel supply, and prime the fuel system to check carefully for any fuel leaks before starting; test-run the engine only with a proper cooling water supply connected, and shut down immediately if any fuel leakage or throttle sticking 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.
• Check the individual year entry and any serial-number or version restrictions.
• 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.
• Note that the listed Yamaha F40 (40 HP) application is limited to 1999, whereas the F50 (50 HP) applications cover 1995 through 2000.
• If you are servicing multiple carburetors on a multi-cylinder outboard, verify how many repair kits your full service job requires.
