Fitment
The 3R4032000M Carburetor from XR Marine fits Nissan / Tohatsu MFS6A2, NSF6A2, MFS6B, and NFS6B (6 HP) 4-Stroke outboard engines in the applications listed below.
Verify the complete model code on your outboard identification plate against the individual entries below, and compare your existing carburetor part number—including its full suffix—before ordering. Horsepower alone cannot confirm fitment; for engines marked NFS6B or NSF6B, verify the exact model designation and part reference prior to purchase.

What's Included
Check the supplied components before planning your repair.
- Carburetor — OEM references: 3R4032000M; 3R4032001M; 3R4032000; 3R4032001; 3R4-03200-0; 3R4-03200-1; 3CJ-032001-1.

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.
- Preparation & Part Comparison: Ensure the engine is shut off and cool, disconnect the ignition source, shut off the fuel supply, and work in a well-ventilated area away from open flames. Compare the replacement carburetor side-by-side with your existing unit to confirm matching mounting flanges, throttle and choke linkage positions, and fuel inlet orientation.
- Removal & Mounting: Note or photograph the routing of all fuel hoses, breathers, and linkage rods before removal. Remove the old carburetor according to your Nissan / Tohatsu service manual, inspect the intake sealing surfaces, and verify that the proper mounting gasket (such as reference 3H6-02011-0 if required by your manual) is in serviceable condition before installing the replacement unit.
- Linkage Check & Leak Inspection: Reconnect the fuel line and linkages, verifying that the throttle and choke move smoothly through their full range without binding. Prime the fuel system to check for any fuel seepage before starting, and perform any necessary idle adjustments only with a proper cooling water supply connected to the outboard; shut the engine down immediately if leaks or abnormal operation 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 engine model code and consult your engine parts catalog for any production year or serial-number distinctions.
- 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.
- For an outboard marked NFS6B or NSF6B, confirm the exact model designation on your engine nameplate and match the carburetor part number before purchase.
- Remember that this listing is for the carburetor itself, whereas numbers 3H6-02011-0, 3H6020110, and 3H6020110M identify the associated carburetor gasket.

Contact XR Marine About WarrantyFrequently Asked Questions
Answers to common questions about this product and its application.
Which Nissan / Tohatsu outboard models fit this carburetor?
This carburetor is listed to fit 6 HP, 4-Stroke Nissan / Tohatsu outboard models MFS6A2, NSF6A2, MFS6B, and NFS6B. Always match your complete engine model code and compare the OEM reference number on your original carburetor rather than relying on horsepower alone.
What should I check if my engine is marked NFS6B or NSF6B?
If your outboard is marked NFS6B or NSF6B, check the exact model designation on the identification plate and verify the complete carburetor OEM reference number (such as 3R4032000M, 3R4032001M, 3R4-03200-0, 3R4-03200-1, or 3CJ-032001-1) before purchasing.
What do part numbers 3H6-02011-0, 3H6020110, and 3H6020110M refer to?
Numbers 3H6-02011-0, 3H6020110, and 3H6020110M are reference numbers for the associated carburetor gasket, not the carburetor itself. This product is a replacement carburetor, not a gasket.
Why is it important to keep the full suffix when comparing part numbers?
Nissan and Tohatsu part numbers use suffixes (such as -0, -1, or M in 3R4032000M and 3R4-03200-1) to distinguish specific carburetor configurations. Preserving the complete suffix helps ensure you are comparing the exact reference for your engine.
Is the mounting gasket included in the package?

All orders include free shipping with no minimum order value. XR Marine also provides a lifetime warranty covering product quality defects, with normal wear and tear excluded.
