Fitment

The 3G2-03200-0M Carburetor Assembly from XR Marine fits Nissan / Tohatsu M9.9D2 (9.9 HP), M15D2 (15 HP), and M18E2 (18 HP) 2-Stroke outboards, as well as the listed 9.9 HP, 15 HP, and 18 HP 2-Stroke Nissan, Tohatsu, Mercury, and Mariner outboard applications below.

Verify the full engine model designation on your identification plate—including suffixes such as D2 or E2—and compare the complete OEM carburetor reference number before ordering. Horsepower alone cannot confirm interchangeability, and numbers such as 803687T02, 803687T03, or 803687T04 should not be treated as interchangeable with 803687T01 without application confirmation.

What's Included

Check the supplied components before planning your repair.

  • Carburetor Assembly — Included (1 unit recorded in primary package listing)
  • Mounting Gasket (OEM reference 27-803699001 / 27-803699 ) — Confirm gasket inclusion and quantity 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. Verify Part Identification and Prepare the Engine: Confirm the engine model designation on the identification plate and compare your existing carburetor's part number and mounting flanges with the replacement assembly. Shut off the engine, allow it to cool completely, disconnect the ignition and fuel supply according to your service manual, and work in a well-ventilated area away from any ignition sources.
  2. Document Connections and Remove the Old Carburetor: Note or photograph the routing and orientation of all fuel lines, throttle linkages, and choke connections before removal. Unbolt the existing carburetor assembly carefully, inspect the intake mounting surface, and clean off any old gasket residue without scratching the mating surfaces.
  3. Install the Replacement Assembly and Perform Checks: Position the appropriate mounting gasket and secure the new carburetor assembly following the sequence in your service manual. Reconnect the fuel line and linkages, verify smooth and unobstructed throttle and choke operation across their full travel, prime the fuel system to check for any fuel leaks, and perform any required idle or mixture adjustments with a proper cooling water supply connected. Stop immediately if any leak or binding is detected.

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 the specific model suffix (such as D2 or E2 on Tohatsu/Nissan outboards) and any applicable serial-number or version details in your 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 803687T02, 803687T03, or 803687T04 as interchangeable with 803687T01 without confirming your exact engine application.
  • Confirm gasket 27-803699001 and its package inclusion separately before starting your installation.

Frequently Asked Questions

Answers to common questions about this product and its application.

Is this product a complete carburetor assembly or a repair kit?

This product is a replacement carburetor assembly, not a rebuild or repair kit. It is used to replace the carburetor unit on matching 9.9 HP, 15 HP, and 18 HP 2-stroke outboard applications.

How do I confirm if this carburetor fits my Tohatsu or Nissan outboard?

Check the identification plate on your engine for the complete model code, including suffixes such as D2 or E2 (for example, M9.9D2, M15D2, or M18E2), and match your existing carburetor's OEM part number against the listed 3G2-03200-0M or 3G2-03100 series references. Do not rely on horsepower rating alone.

Are Mercury/Mariner numbers 803687T02, 803687T03, or 803687T04 directly interchangeable with 803687T01?

Do not treat 803687T02, 803687T03, or 803687T04 as automatically interchangeable with 803687T01 or 3303-803687A1. Always verify the exact suffix required by your engine's parts catalog or contact XR Marine with your engine details before ordering.

Is mounting gasket 27-803699001 included in the package?

Contact XR Marine to confirm the supplied contents and quantities before ordering.

Will this fit a 4-stroke 9.9 HP, 15 HP, or 18 HP outboard?

No. This carburetor is specified only for the listed 2-stroke outboard applications. Even if the horsepower matches, 2-stroke and 4-stroke engines use different carburetor designs.

What shipping and warranty coverage apply to this carburetor?

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.
