Product Overview

XR MARINE · CARBURETORS & REPAIR KITS

3P0-03200-0 Carburetor Fits Tohatsu / Nissan M25C3, M30A4 - XR Marine

This product is a replacement carburetor assembly for the specified 25 HP and 30 HP two-stroke outboard applications across Tohatsu, Nissan, Mercury, and Mariner engines. It is a complete carburetor unit intended for assembly replacement rather than a carburetor repair kit.

Tohatsu and Nissan applications require matching the full model designation (M25C3, M30A4, NS25C3, or NS30A4) and the 2002–2005 model years, while Mercury and Mariner 25 HP and 30 HP two-stroke applications from 2001–2006 are limited to International versions. Always verify the full engine model, production year, market version, and complete carburetor reference number before ordering.

Free shipping on all orders. Lifetime warranty for product quality defects. Normal wear and tear excluded.

OEM & Part Number References

Use the complete reference number, including its suffix, when comparing parts. Reference numbers do not confirm that every version is interchangeable.

Keep all prefixes and suffixes such as “3303-”, “A1”, “A8”, and “M” when checking your original carburetor reference. No supersession direction between A1 and A8 is specified.

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 Verification: Confirm the engine is shut off and cool, isolate the fuel supply and ignition system in accordance with your service manual, and work in a well-ventilated area away from ignition sources. Compare the replacement carburetor assembly against the existing unit, checking mounting flanges, fuel inlet orientation, linkage connection points, and public part markings.
  2. Removal and Assembly Installation: Document the routing of fuel hoses, throttle and choke linkages before removing the original carburetor. Remove the old carburetor per your service manual, inspect the mounting surface, and install the replacement carburetor assembly while ensuring throttle and choke mechanisms move freely through their full range without binding.
  3. Fuel Leak Check and Service Manual Adjustments: Reconnect the fuel line, restore fuel supply, and inspect all connections and carburetor seams for any signs of fuel leakage before starting. With a proper cooling water supply connected to the outboard, start the engine and perform any idle or linkage checks specified in your engine service manual; shut down immediately if any fuel leak, throttle sticking, 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.
  • 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.
  • For Tohatsu and Nissan outboards, verify the exact model code (M25C3, M30A4, NS25C3, or NS30A4) and confirm a 2002–2005 production year.
  • For Mercury and Mariner outboards, confirm that your engine is a 25 HP or 30 HP 2-Stroke International version from 2001–2006.

Frequently Asked Questions

Answers to common questions about this product and its application.

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

This product is a complete carburetor assembly for the listed 25 HP and 30 HP two-stroke outboard applications. It is not a carburetor repair kit.

Which Tohatsu and Nissan outboard models does this carburetor fit?

It fits two-stroke Tohatsu M25C3 (25 HP) and M30A4 (30 HP) as well as Nissan NS25C3 (25 HP) and NS30A4 (30 HP) outboard models from production years 2002, 2003, 2004, and 2005. Check your engine identification plate to confirm the complete model code before ordering.

Does this carburetor fit all Mercury and Mariner 25 HP and 30 HP outboards?

No. Mercury and Mariner applications are restricted to International versions of the 25 HP and 30 HP two-stroke outboards from model years 2001 through 2006. Always verify your market version and original carburetor part number before purchasing.

How should I compare reference numbers with suffixes like A1, A8, or M?

Always preserve all prefixes and suffixes—such as “3303-”, “A1”, “A8”, and “M”—when matching your original carburetor number against the reference list. No supersession direction between A1 and A8 is specified, so do not assume similar-looking numbers are interchangeable without verifying your exact engine application.

Can I select this carburetor based on 25 HP or 30 HP rating alone?

No. Horsepower alone is not sufficient to select the right carburetor. You must confirm the complete engine model designation, stroke configuration (2-Stroke), production year, market version, and original reference number.

What shipping and warranty policies 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.
