Product Overview

XR MARINE · CARBURETORS & REPAIR KITS

689-W0093-01 Carburetor Repair Seal Kit Fits Yamaha Outboard 25, C25 (25 HP)

This product is a carburetor repair seal kit (also referenced in product records as a Fuel Systems Carburetor Repair Kit) designed for servicing carburetors on the specified Yamaha Outboard and Mercury Mariner applications. It is a repair kit for carburetor sealing and maintenance rather than a complete carburetor assembly. Because different 25 HP, 28 HP, and 30 HP outboards use distinct carburetor configurations, always match the complete engine model prefix, model year, and full part reference number—including its suffix—instead of relying on horsepower alone.

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

Fitment

The 689-W0093-01 Carburetor Repair Seal Kit from XR Marine fits Yamaha Outboard 25 (25 HP, including 2-cylinder Sierra 18-7770 catalog reference applications), C25 (25 HP), 30 (30 HP), and C30 (30 HP) outboards, as well as Mercury Mariner 25 (25 HP with A/C application designation), 28 (28 HP), and 30 (30 HP) outboards in the model-year and application entries listed below.

Verify the complete engine model designation on your identification plate—paying close attention to prefixes such as standard 25/30 versus C25/C30—along with the individual model year and full part reference number including its suffix. For Mercury Mariner applications where the year or full model code is not specified in the reference record, confirm the exact model designation, A/C application requirement, and serial-number information against your service catalog, as horsepower alone cannot confirm fitment.

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 identification and prepare the work area: Confirm the engine model designation on the identification plate and compare the full part reference number before disassembly. Shut off the engine, allow it to cool completely, isolate the fuel supply and ignition system as directed by your service manual, and work in a well-ventilated area away from ignition sources.
  2. Disassemble and compare sealing components: Record the routing of fuel hoses and the orientation of throttle and choke linkages before removing or opening the carburetor. Disassemble the carburetor sections according to the service manual, clean the mating surfaces carefully, and compare each supplied seal or component against the original part to ensure an exact match.
  3. Reassemble and inspect for fuel leaks: Install only the matching kit components, reassemble the carburetor, and complete any required adjustments strictly according to your engine service manual. Restore the fuel supply and inspect all joints for leaks before starting; run the engine only with the proper cooling water supply connected, and shut it down immediately if any fuel leak, linkage binding, or abnormal running 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 Yamaha applications, distinguish between standard 25/30 models (1984–1987 for 25 HP; 1984–1986 for 30 HP), C25/C30 models (1990–1997 for C25; 1990–1992 for C30), and CV-series models—note that CV25 and CV30 appear only in supplementary Sierra catalog references and are not listed as direct applications here.
  • For Mercury Mariner 25 HP, 28 HP, and 30 HP applications, verify the exact model designation (such as the 25 HP A/C application designation), serial number, and carburetor version against reference 84456M.

Frequently Asked Questions

Answers to common questions about this product and its application.

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

This product is a carburetor repair seal kit (also identified in product records as a Fuel Systems Carburetor Repair Kit) for servicing existing carburetors on the specified Yamaha Outboard and Mercury Mariner engines. It is not a complete carburetor assembly.

Why does the model prefix matter when selecting a kit for a Yamaha 25 HP or 30 HP outboard?

Matching horsepower alone is not sufficient because different model series have distinct year ranges and carburetor specifications. In the listed applications, standard Yamaha 25 models cover 1984–1987 (including 2-cylinder Sierra 18-7770 catalog reference entries) and standard 30 models cover 1984–1986, whereas C25 models cover 1990–1997 and C30 models cover 1990–1992. Always check whether your engine identification plate specifies a standard 25/30, C25/C30, or CV-series model.

Does this kit fit Yamaha CV25 or CV30 outboards?

CV25 and CV30 appear only as supplementary Sierra catalog reference applications rather than direct company-listed applications on this page. If you have a CV25 or CV30 engine, verify your exact carburetor part number and suffix against your parts catalog or contact XR Marine with your engine details before ordering.

How should I confirm fitment for a Mercury Mariner 25 HP, 28 HP, or 30 HP engine?

The Mercury Mariner fitment records list 25 HP (with the A/C application designation), 28 HP, and 30 HP without specifying individual model years. Before ordering, confirm your exact Mariner model designation, A/C application code, and engine serial number against OEM reference 84456M.

Which OEM and aftermarket part numbers are referenced for this kit?

This kit references Yamaha Outboard numbers 689-W0093-01, 689-W0093-02, 689W00930100, 689W009302, 689W00930200, 689-W0093-00-00, 689-W0093-01-00, and 689-W0093-02-00; Mercury Mariner 84456M; Sierra 18-7770; GLM 40690; RECMAR REC689-W0093-02; and additional reference numbers 689-W0093 and 689-W0093-00. Always compare the complete number including its suffix.

How many kits are required per engine, and how can I check the exact package contents?

According to the product specifications for the Sierra reference application, 1 carburetor kit is required per engine. Because an itemized component list is not specified on this page, please contact XR Marine before ordering if you need to confirm the exact supplied contents for your repair.
