Product Overview
XR MARINE · CARBURETORS & REPAIR KITS
3LD-03100-1 Carburetor
This XR Marine product is a replacement carburetor associated with Nissan and Tohatsu marine outboard OEM reference numbers 3LD-03100-1, 3LD-03100-2, and 3LD03100M. It is supplied as a single carburetor unit (quantity: 1) rather than a carburetor repair kit.
It is intended for carburetor replacement where the required OEM reference number and exact engine configuration have been verified beforehand. Always check the complete part number including its suffix rather than selecting by horsepower or brand name alone.
Product Specifications
Key product details for identification and comparison.
Fitment
The 3LD-03100-1 Carburetor from XR Marine requires verification of the complete engine model, model year, and exact OEM reference number on your Nissan or Tohatsu marine outboard before ordering.
Match the complete model designation on your engine identification plate and compare the full carburetor reference number—including its suffix—against your official parts catalog. Do not select a replacement carburetor by horsepower or brand name alone, and do not assume that numbers such as 3LD-03100-0, 3LD-03100-1, 3LD-03100-2, and 3LD03100M are automatically interchangeable.
Fitment to Confirm

Check the supplied components before planning your repair.
- Carburetor — Quantity: 1 (Associated with OEM reference numbers 3LD-03100-1, 3LD-03100-2, 3LD03100M)
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 and Verification: Ensure the engine is shut off and cool, disconnect the ignition source, and isolate the fuel supply in a well-ventilated workspace away from open flames. Before removing the existing unit, compare the replacement carburetor's mounting flanges, throttle and choke linkage points, fuel inlet orientation, and reference markings against the original assembly.
- Removal and Installation: Document the routing of all fuel hoses, vent tubes, and linkage rods before disassembly. Remove the old carburetor according to your engine service manual, inspect the intake mating surfaces for cleanliness and damage, and install the new carburetor following the manual's specified fastening sequence and linkage connections.
- Fuel Inspection and Operational Check: Reconnect the fuel supply and inspect all hose connections and carburetor seams for any signs of fuel leakage before starting. Confirm that throttle and choke linkages move smoothly without binding. With proper cooling water supplied to the outboard, start the engine and perform any idle or mixture adjustments strictly according to the factory service manual. Shut down immediately if any fuel leak or abnormal operation 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.
- Verify your engine's model year and serial-number details against your official parts catalog before ordering.
- 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 3LD-03100-0, 3LD-03100-1, 3LD-03100-2, and 3LD03100M as automatically interchangeable solely because the numbers look similar.
- Confirm that you require a complete replacement carburetor unit rather than an internal carburetor repair kit.
