688-14301-40 Carburetor Fits Yamaha Outboard (85 HP)
This XR Marine carburetor product is listed for replacement work on Yamaha 85 HP, 3-cylinder, 2-stroke outboard motors. On a 3-cylinder setup, the listed OEM references distinguish between the top, middle, and lower carburetor positions. Because different mounting positions and part-number suffixes are not established as interchangeable, verify both the required carburetor position on your engine and the complete OEM reference number 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.
- Verify Part Number and Position: Compare the replacement carburetor against your original unit and the Yamaha parts catalog. Confirm that the part number, suffix, and mounting position (top, middle, or lower) match the exact location being serviced.
- Prepare the Engine Safely: Shut off the engine and let it cool completely. Disconnect the battery, isolate the fuel supply according to your service manual, and work in a well-ventilated area away from open flames or sparks.
- Label Hoses and Linkages: Before disassembly on a 3-cylinder, multi-carburetor outboard, document or photograph the routing of all fuel lines, choke linkages, and throttle synchronization rods connected to the top, middle, and lower positions.
- Remove the Existing Carburetor: Follow the factory service manual to remove the intake silencer or air box, disconnect the fuel hoses and linkage clips carefully, and unbolt the carburetor from the intake manifold while catching any residual fuel.
- Inspect Mating Surfaces and Interfaces: Clean the mounting flange surfaces thoroughly without gouging the metal. Compare the flange bolt pattern, throttle lever orientation, and fuel inlet fittings of the new unit with the removed carburetor.
- Install and Synchronize: Mount the carburetor using appropriate gaskets and tighten fasteners according to the sequence and specifications in your Yamaha service manual. Reconnect all fuel lines and linkages, then verify smooth, full-range throttle and choke movement across all cylinders.
- Check for Leaks and Perform Water-Supplied Test: Reconnect the fuel supply and prime the system while inspecting all fittings and gaskets for fuel leaks. Only start the outboard with proper cooling water supplied, and follow the service manual for idle and multi-carburetor synchronization adjustments. Shut down immediately if any leak, binding linkage, 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 model code and serial number against the official Yamaha parts diagram for your 85 HP, 3-cylinder, 2-stroke outboard.
- 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.
- Identify the exact carburetor position required: top (688-14301-40 / 692-14301-36), middle (688-14302-40 / 692-14302-36), or lower (688-14303-40 / 692-14303-36). Different positions and suffixes are not established as interchangeable.

Contact XR Marine About WarrantyFrequently Asked Questions
Answers to common questions about this product and its application.
How do the top, middle, and lower carburetor part numbers differ on a Yamaha 85 HP 3-cylinder outboard?
On this 3-cylinder 2-stroke setup, the listed OEM numbers distinguish each mounting position: 688-14301-40 / 692-14301-36 for the top position, 688-14302-40 / 692-14302-36 for the middle position, and 688-14303-40 / 692-14303-36 for the lower position. Always check which position you are replacing and match the full part number including its suffix.
Are the different carburetor positions or part-number suffixes interchangeable?
No. Different carburetor positions (top, middle, and lower) and different part-number suffixes are not established as interchangeable. Compare your complete OEM reference number against the parts diagram for your specific engine before ordering.
Is this product a carburetor or a carburetor repair kit?
This listing is for a carburetor product intended for carburetor replacement work on a Yamaha 85 HP, 3-cylinder, 2-stroke outboard, rather than a gasket or rebuild kit. Contact XR Marine before ordering to confirm the exact supplied contents and position configuration.
How can I verify fitment if my exact model code or production year is not listed?
Because the fitment data specifies a Yamaha 85 HP, 2-stroke, 3-cylinder outboard without an individual model code or year breakdown, you should verify the OEM part number from your engine's parts catalog or existing carburetor stamping. You can also send your engine identification plate details and photos to XR Marine for assistance.
What is included in the package when I order?
Contact XR Marine to confirm the supplied contents and quantities before ordering.
What shipping and warranty policies apply to this carburetor?
XR Marine offers free shipping on all orders with no minimum order value, along with a lifetime warranty covering product quality defects (normal wear and tear is excluded).
