Product Details
This aftermarket fuel pump is intended as a replacement for selected Yamaha and Mercury/Mariner 4-stroke outboard applications. It is listed for Yamaha applications in the 20–60 HP range and Mercury/Mariner applications in the 25–60 HP range. Confirm the exact engine model, year, original pump design, connection layout, and part number before ordering.
The pump is listed as a replacement reference for Yamaha part numbers 62Y-24410-00-00, 62Y-24410-01-00, 62Y-24410-02-00, 62Y-24410-03-00, and 62Y-24410-04-00, and Mercury references 826398A1, 826398A3, and 826398T3. These numbers should be compared with the number on the pump being replaced; number co-occurrence alone does not confirm fitment for every engine configuration.
- Aftermarket replacement fuel pump for selected gasoline outboard applications.
- Metal housing intended for use in marine fuel-system environments.
- Direct-replacement style design; compare mounting, ports, and electrical connections before installation.
- Sold as one fuel pump rather than a complete fuel-system assembly.

This is a single replacement pump, not a complete pump assembly or engine fuel-system kit. Hose clamps, clips, O-rings, mounting hardware, and other installation parts should not be assumed unless they are specifically shown or stated in the order details. Reuse hardware only when it is serviceable and approved for the application.
Installation Notes
- Disconnect the negative battery terminal and follow all applicable marine fuel-system safety procedures.
- Relieve fuel-system pressure according to the engine service manual before disconnecting any fuel line.
- Work in a well-ventilated area away from flames, sparks, heat, and ignition sources. Use absorbent towels to control spilled fuel.
- Photograph or label the original hose and electrical-connector positions before removing the old pump.
- Disconnect the fuel lines and electrical connector, then remove the original mounting hardware.
- Compare the replacement pump with the original unit, including mounting points, inlet and outlet positions, thread size, hose-barb size, and electrical connections.
- Install only the correct fuel-resistant seals and hardware for the engine. Do not force mismatched fittings or alter the fuel-system configuration.
- Secure the replacement pump with suitable hardware and reconnect each line and electrical connection to the correct port.
- Reconnect the battery, prime the fuel system as specified by the service manual, and inspect carefully for leaks before starting the engine.
- After starting, recheck for fuel leakage and abnormal pump noise. Stop immediately if a leak or connection problem is found.
Troubleshooting and FAQ
How do I confirm this fuel pump is correct?
Compare the original pump's manufacturer number, engine brand, model code, horsepower, stroke, year, serial-number range when applicable, connector, mounting arrangement, and inlet/outlet configuration. A visual comparison and service-manual check are recommended before ordering.
What symptoms can indicate a failing fuel pump?
Possible symptoms include hard starting, stalling, hesitation, loss of power, poor operation at higher throttle, or inadequate fuel delivery. These symptoms can also result from blocked filters, restricted hoses, wiring faults, fuel contamination, or other engine problems, so diagnose the complete system before replacing the pump.
Does this pump have a fixed replacement interval?
Fuel pumps are generally replaced when testing shows a fault or when performance has degraded. Follow the engine manufacturer's inspection and maintenance schedule, and address fuel contamination or restrictions that could damage a replacement pump.
Is this an OEM part?
No. This listing is for an aftermarket replacement fuel pump. The reference numbers are provided for identification and application comparison only; the pump is not represented as an original manufacturer component.
What should I do if the connections do not match?
Do not force the installation or modify fuel-system connections to make the pump fit. Stop installation and compare the original part, engine service information, and the applicable reference number.
Safety and Important Information
- Verify the complete application before purchase and installation; horsepower alone is not sufficient to confirm fitment.
- Use only fuel-system-compatible hoses, seals, clamps, and fittings.
- Never operate the engine when fuel is leaking or when fuel vapors are present.
- This is an aftermarket replacement, not an OEM component.
- Professional installation is recommended if you are not experienced with marine fuel systems.
