Product Details
This aftermarket carburetor assembly is listed for Yamaha 75 HP and 85 HP 2-stroke outboard applications. It is intended as a replacement for the carburetor identified by Yamaha part number 688-14301-08. Before ordering, compare the part number, mounting arrangement, linkage connections, and product images with the carburetor removed from your engine.
Because outboard fitment can vary by model configuration and production specification, the horsepower rating alone is not sufficient to confirm compatibility. Verify your complete engine model and the number on your original carburetor before installation.
- Aftermarket carburetor assembly for selected Yamaha 75/85 HP 2-stroke outboards.
- Designed as a replacement for the Yamaha reference number listed below.
- Uses OEM-style mounting and connection points for the applicable engine application.
- Inspect all fuel lines, linkages, seals, and mounting hardware before installation.
Part Number Reference
Use the following manufacturer reference to compare your original component. A matching number is an important fitment check, but the complete engine model and configuration should also be verified.

Troubleshooting & FAQ
How do I confirm that this carburetor will fit my engine?
Confirm that your engine is a Yamaha 75 HP or 85 HP 2-stroke outboard, then compare the complete engine model, original carburetor, mounting pattern, linkage arrangement, and reference number 688-14301-08. If any of these details differ, contact the seller before ordering.
Does this fit Yamaha 4-stroke engines?
Compatibility is listed for Yamaha 2-stroke applications only. Do not use this listing to establish fitment for a 4-stroke engine.
Does this fit Yamaha 25-40 HP or other brands?
No such applications are confirmed by the available product record. Do not assume compatibility with smaller Yamaha models, Selva, Parsun, Hidea, Seapro, HDX, or other brands without a separately verified matching part number and application.
What should I inspect before installing the replacement?
Check the fuel lines, filter, tank, mounting surface, gasket, throttle and choke linkages, and fuel connections. Contaminated fuel or debris elsewhere in the system can affect the replacement carburetor.
Are adjustments needed after installation?
Follow the service procedure for your exact engine model. Idle or mixture settings may require checking after installation, but adjustments should be made only within the manufacturer's specified limits.
What are common symptoms of a carburetor or fuel-system problem?
Possible symptoms include hard starting, unstable idle, stalling, hesitation during acceleration, poor throttle response, fuel leakage, or an overly rich or lean running condition. These symptoms can also be caused by fuel contamination, ignition faults, air leaks, or incorrect adjustment.
Is this a genuine Yamaha part?
No. This listing is for an aftermarket replacement carburetor assembly intended for the stated application. Yamaha is referenced only for engine and replacement-part identification.
Safety & Important Information
- Fuel is flammable. Work in a ventilated area with the engine stopped and away from ignition sources.
- Verify the complete engine model, stroke, original carburetor, and reference number before ordering.
- Do not rely on horsepower alone to confirm fitment.
- Use new sealing components where required and check carefully for fuel leaks before operation.
- Professional installation is recommended if you are not familiar with outboard fuel systems.
