Product Overview
XR MARINE · CARBURETORS & REPAIR KITS
689-W0093-01 Carburetor Repair Seal Kit Fits Yamaha Outboard 25, C25 (25 HP)
This Carburetor Repair Seal Kit (also referenced as a Fuel Systems Carburetor Repair Kit) is designed for carburetor repair and sealing service on specified Yamaha Outboard and Mercury Mariner outboard applications. It is a repair and seal kit for servicing existing carburetor components, not a complete carburetor assembly.
Because 25 HP and 30 HP outboards use different carburetor configurations across model prefixes and production years, select this kit by matching the complete engine model designation, model year, and full repair-kit reference number rather than horsepower alone.
Product Specifications
Key product details for identification and comparison.
Fitment
The 689-W0093-01 Carburetor Repair Seal Kit from XR Marine fits Yamaha Outboard 25 (25 HP, including 2-cylinder catalog reference entries), 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 applications listed below.
Match the complete model designation on your engine identification plate—including prefixes such as C25 or C30—against the individual year entries below, and compare the full OEM part number with its suffix. For Mariner applications where the model year or full designation is not specified, confirm the exact model designation, A/C application designation, and serial-number details before ordering, as horsepower alone cannot confirm fitment.

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.
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.
- Verify identification and prepare the workspace: Confirm your engine model designation, year, and OEM repair-kit number before starting work. Shut off the engine, allow it to cool completely, disconnect the battery or disable ignition, and isolate the fuel supply in a well-ventilated area away from ignition sources.
- Disassemble and compare existing seals and parts: Note the routing of fuel lines and linkage positions before removing the carburetor. Disassemble the carburetor according to your service manual, inspect the internal passages and sealing surfaces, and compare each removed seal or component directly with the supplied parts in the kit. Replace only the components that match your specific carburetor configuration.
- Reassemble and check for fuel leaks: Reassemble the carburetor and reinstall it on the outboard following the procedures and specifications in your service manual. Reconnect the fuel supply and inspect all joints and gaskets for fuel leaks before starting; only run the engine with proper cooling water supplied, and stop immediately if any fuel leak, throttle binding, 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 Yamaha applications, distinguish between standard 25/30 models, C25/C30 models, and CV-series models, as each series has specific model-year boundaries (CV25 and CV30 appear only in supplementary Sierra catalog references, not as company-listed direct applications).
- For Mercury Mariner 25, 28, and 30 HP applications, verify the exact model designation, A/C application designation, and serial-number information with your parts catalog before ordering.

Contact XR Marine About WarrantyFrequently 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 Carburetor Repair Seal Kit (also referred to as a Fuel Systems Carburetor Repair Kit) for carburetor repair and sealing service. It is not a complete carburetor assembly.
Can I select this kit based only on my outboard being 25 HP or 30 HP?
No. Matching horsepower alone is not sufficient. For Yamaha outboards, standard 25 (1984–1987) and 30 (1984–1986) models have different model-year limits than C25 (1990–1997) and C30 (1990–1992) models. Always check your exact model prefix, year, and OEM part number before ordering.
Does this kit fit Yamaha CV25 or CV30 outboards?
CV25 and CV30 appear only as supplementary Sierra catalog reference applications and are not listed as direct company applications for this kit. Verify the exact OEM part number required for your CV-series carburetor or contact XR Marine before ordering.
How do I confirm fitment for Mercury Mariner 25, 28, or 30 HP applications?
The Mariner listings cover 25 HP (with A/C application designation), 28 HP, and 30 HP applications where model years and full model designations are not specified. Before ordering, confirm your exact Mariner model designation, serial-number information, and whether your carburetor calls for OEM reference 84456M.
What OEM and aftermarket part numbers are referenced for this kit?
Referenced numbers include Yamaha Outboard 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 references 689-W0093 and 689-W0093-00. Always compare the full number, including its suffix, as reference numbers do not guarantee every version is interchangeable.
What components are included in the package, and how many kits are required per engine?
According to the Sierra catalog specification for reference 18-7770, 1 carburetor kit is required per engine. Because individual seal and component counts are not itemized on this page, please contact XR Marine before ordering to confirm the exact supplied contents for your repair.
