Product Details
This is an aftermarket fuel pump assembly for selected Yamaha 2-stroke 115–300 HP outboards. Catalog references identify this pump for Yamaha outboard fuel systems across applicable V4 and V6 applications, with documented coverage from 1984 through 2004. It is intended to restore mechanical fuel delivery when the original pump is worn, leaking, or no longer maintaining proper fuel flow.
This fuel pump is listed as a replacement for Yamaha part numbers 6E5-24410-10-00 and 6E5-24410-03-00, with Sierra reference 18-7349. Always confirm the complete engine model, year, serial-number range where applicable, mounting arrangement, and the part number on the original pump before ordering.
- Mechanical fuel pump assembly for compatible Yamaha 2-stroke outboards.
- Front-mount configuration as shown for the applicable replacement design.
- Sold as a fuel pump assembly; gaskets, diaphragms, clamps, and mounting hardware are not confirmed as included unless specifically stated by the seller or shown in the package contents for the order.
- For applications requiring a service rebuild kit, catalog references identify Yamaha V4/V6 fuel-pump kit Sierra 18-7788 as a separate component.

What’s in the Box
- 1 x Fuel Pump Assembly
Replacement gaskets, diaphragms, hose clamps, and mounting hardware are not confirmed as included with this single pump assembly. Obtain any required service components separately unless the actual package listing specifically states otherwise.
Installation Notes
- Disconnect the battery, shut off the fuel supply, and allow the engine to cool before beginning work.
- Relieve residual fuel pressure and place absorbent rags beneath the pump to contain spills.
- Label the fuel hoses before removal, then disconnect the hoses and inspect them for cracking, hardening, or contamination.
- Remove the fasteners securing the original pump and carefully remove the pump from the engine.
- Clean the mounting surface and remove old gasket material without damaging the mating surfaces.
- Install the correct new gasket or sealing components for the exact engine application. These components are not confirmed as included with this pump assembly.
- Mount the replacement pump and tighten the fasteners according to the engine manufacturer's service instructions.
- Reconnect the fuel hoses to the correct ports and secure them with suitable clamps.
- Reconnect the battery, prime the fuel system according to the engine manual, and inspect carefully for leaks before starting.
- Stop immediately and correct any leak, fuel odor, abnormal noise, or fuel-delivery problem before operating the outboard.
Troubleshooting & FAQ
How do I know if my fuel pump is failing?
Common symptoms can include hard starting, stalling, hesitation, sputtering at higher speed, loss of power, inadequate fuel delivery, or fuel leakage around the pump and its fittings. Test the complete fuel system before replacing the pump because clogged filters, damaged hoses, carburetor issues, and crankcase-pressure problems can produce similar symptoms.
Will this fit my Yamaha 250 HP engine?
Some Yamaha 250 HP 2-stroke models are documented in the application references, including selected LX and SX models from the applicable years. Fitment depends on the complete model code, year, serial range, mounting arrangement, and original pump number. Confirm those details before ordering rather than relying on horsepower alone.
Does the assembly include a gasket or rebuild kit?
This listing is for the fuel pump assembly itself. A gasket, diaphragm, clamp, or mounting-hardware package is not confirmed as included. The Sierra 18-7788 V4/V6 fuel-pump kit is identified separately in catalog material and should not be assumed to be part of this pump assembly.
What replacement references should I compare?
Compare the number on your original pump with Yamaha 6E5-24410-10-00 or 6E5-24410-03-00 and the Sierra 18-7349 interchange reference. Also compare the pump's mounting and hose-port arrangement before installation.
Is this an OEM Yamaha pump?
No. This listing is for an aftermarket replacement. Yamaha and Sierra numbers are shown only as OEM and aftermarket reference numbers for identification and compatibility checking.
What fuel should be used?
Use fuel that meets the requirements in your Yamaha engine owner's or service manual. Keep fuel fresh, use a clean fuel system, and inspect hoses and connections regularly, especially after storage.
What is the recommended replacement interval?
There is no universal replacement interval for every Yamaha application. Inspect the pump during routine service and replace it if it leaks, fails a fuel-delivery test, or shows signs of deterioration.
Safety & Important Info
- Fuel is flammable. Work in a well-ventilated area away from sparks, flames, and other ignition sources.
- Verify the complete engine model, year, serial information, original part number, mounting pattern, and hose connections before purchase.
- Do not rely on horsepower alone to establish compatibility.
- This is an aftermarket replacement, not an OEM Yamaha component.
- Professional installation is recommended if you are unfamiliar with marine fuel-system service.
