- Tighten the mounting hardware to the engine manufacturer's specified torque. Do not overtighten.
- Reconnect the fuel lines and secure all connections.
- Prime the fuel system, start the engine, and inspect the pump and fittings carefully for fuel leaks.
Fuel-system work should be performed by a qualified technician when the correct procedure, torque values, or engine-specific service information is not available.
Troubleshooting & FAQ
How do I confirm fitment for my Mercury outboard?
Compare the complete engine model, horsepower, stroke, and serial number with the compatibility table. Serial-number verification is especially important because similar horsepower ratings may use different fuel-pump applications.
What are common symptoms of a failing two-stroke fuel pump?
Possible symptoms include hard starting, rough idle, stalling, hesitation or bogging at higher RPM, reduced power, and fuel leakage. Diagnose the fuel system before replacing the pump, since similar symptoms can have other causes.
Is this an OEM Mercury part?
No. This listing is for an aftermarket replacement kit associated with the Mercury reference numbers shown above. It is not manufactured or warranted by Mercury Marine.
Does the kit include the complete pump assembly?
This listing is for a fuel pump kit with the supplied gaskets, springs, and diaphragms shown in the package description. Confirm the kit contents against the original assembly before installation.
How often should the fuel pump be replaced?
There is no universal replacement interval. Inspect the pump during routine service and replace it if there is leakage, visible deterioration, insufficient fuel delivery, or other confirmed malfunction.
What should I do if the pump does not match my original part?
Do not force installation or modify the component. Recheck the engine serial number and the replacement references, then contact support before installation.
Safety & Important Information
- Verify the model, horsepower, stroke, serial number, and original part reference before ordering.
- Do not rely on horsepower alone to determine compatibility.
- Work in a well-ventilated area away from flames, sparks, and other ignition sources.
- Inspect all fuel lines, fittings, gaskets, and connections for leaks after installation.
- Professional installation is recommended for fuel-system service.
- This is an aftermarket replacement and is not an OEM Mercury component.
