Troubleshooting & FAQ
How do I confirm this fuel pump fits my specific engine?
Compare the original pump’s part number, connection style, mounting arrangement, engine model, horsepower, stroke, year, and serial-number range with the information on this page. The original pump part number and the complete engine identification are the most useful checks; horsepower alone is not sufficient.
What are common signs of a failing outboard fuel pump?
Possible symptoms include hard starting, sputtering, surging, intermittent stalling, loss of power, or the engine bogging down under load. These symptoms can also result from other fuel-system or ignition problems, so diagnose the system before replacing the pump.
Is this a difficult part to install?
Replacement may be straightforward for an experienced marine mechanic, but gasoline presents a fire and health hazard. Use the applicable service information, relieve fuel pressure safely, and consider professional installation if you are not familiar with outboard fuel systems.
Is this an OEM part?
No. This listing is for an aftermarket replacement kit. The listed Mercury numbers are manufacturer reference or cross-reference numbers and do not mean that the replacement is manufactured by Mercury Marine.
What should I do if the replacement does not match my original pump?
Do not force the installation or modify the fuel lines, mounting points, or connections. Compare the part number and engine identification again and contact support before installation if the supplied pump differs from the original.
How should the kit be stored before installation?
Keep the kit sealed and store it in a clean, dry, well-ventilated location away from heat, sparks, flames, fuel contamination, and direct sunlight.
