Product Details
This aftermarket mechanical fuel pump is designed as a replacement for selected Mercury and Mariner 2-stroke outboard applications from approximately 30 to 300 HP. It is intended to restore fuel delivery on compatible carbureted, EFI, and selected DFI applications when the original pump is worn, damaged, or no longer operating correctly.
Fitment varies by engine model, configuration, and serial number. Always compare the original pump, mounting arrangement, hose connections, and engine serial number before ordering. The references below are provided for identification and cross-reference purposes only.
- Aftermarket replacement fuel pump assembly for selected Mercury and Mariner 2-stroke outboards.
- Pulsed diaphragm-style design for compatible outboard fuel systems.
- Direct-replacement style installation when the application, mounting pattern, and connections match.
- Supplied as one fuel pump assembly; installation accessories may include a mounting gasket and cable tie as listed below.

Engine Compatibility
The application information below summarizes the listed 2-stroke fitment coverage. It is not a substitute for checking the exact model designation and serial number on your engine.
| Brand | Application | Rated HP | Stroke | Reference Serial Range | Applicable Reference |
|---|---|---|---|---|---|
| Mercury/Mariner | Selected standard outboards | 30–125 HP | 2-Stroke | Various ranges beginning with 0C, 0D, 0G, 0P, and 0T | 14360A16, 14360A41, 14360A43 |
| Mercury/Mariner | Selected standard, EFI, and DFI outboards | 135–300 HP | 2-Stroke | Various ranges beginning with 0D, 0G, 0T, 1B, and 2B | 14360A78 |
| Mercury/Mariner | Jet applications | 35–140 HP | 2-Stroke | Various ranges beginning with 0D, 0G, and 0T | 14360A78 |
| Mercury/Mariner | V-series, XR-6, SeaPro, Marathon, and Pro Max applications | 135–300 HP | 2-Stroke | Application- and serial-specific | 14360A78 |
Do not rely on horsepower alone for fitment. Mercury and Mariner engines with the same rated horsepower may use different fuel pumps depending on year, model family, fuel system, engine configuration, and serial-number range.

Installation Notes
- Disconnect the battery and allow the engine to cool before servicing the fuel system.
- Relieve fuel-system pressure where applicable and place absorbent material around the fuel lines to contain spills.
- Mark the fuel-hose routing, then carefully disconnect the inlet and outlet hoses from the original pump.
- Remove the mounting fasteners and take off the old fuel pump.
- Clean the mounting surface thoroughly and remove any remaining gasket material or debris.
- Position the new gasket and replacement pump in the original mounting location.
- Tighten the fasteners to the engine manufacturer's specified torque. Do not overtighten.
- Reconnect the fuel hoses to the correct fittings and secure them against leakage or chafing.
- Prime the fuel system according to the engine service information, inspect all connections, and check carefully for fuel leaks before operating the engine.
Follow the engine manufacturer's service procedures whenever they differ from these general installation notes. If the mounting pattern, fittings, diaphragm configuration, or hose routing does not match the original pump, stop installation and verify the application.
Troubleshooting & FAQ
What symptoms can indicate a failing fuel pump?
Possible symptoms include hard starting, hesitation during acceleration, sputtering, loss of power, stalling, or poor operation under load. These symptoms can also be caused by restricted fuel lines, a blocked filter, carburetor problems, ignition faults, or other fuel-system issues.
Will this fit every Mercury or Mariner 2-stroke engine from 30 to 300 HP?
No. The horsepower range is a general application description, not a universal fitment guarantee. Verify the engine model, fuel-system type, serial-number range, mounting arrangement, hose connections, and original pump reference before ordering.
Can this pump be used on DFI or EFI engines?
It is listed for selected EFI and DFI applications, but not every EFI or DFI engine uses the same fuel pump. Confirm the exact model and serial number and compare the original component before installation.
Are the listed part numbers interchangeable in every application?
No. The listed numbers are cross-reference leads associated with different Mercury and Mariner applications and revisions. A matching number must still be checked against the complete engine model and serial-number conditions.
Is a gasket included?
The supplied package may include a mounting gasket and cable tie as listed in the package contents. Check the physical contents when received and do not reuse a damaged or compressed gasket.
Is this an OEM part?
No. This is an aftermarket replacement fuel pump. Mercury and Mariner names and reference numbers are used only to identify the applications and replacement references for which the product is listed.
What maintenance can help protect the replacement pump?
Use clean fuel, replace restricted fuel filters at the recommended intervals, inspect fuel hoses for deterioration, and address water or debris contamination promptly. A fuel pump cannot compensate for a blocked filter, damaged hose, or contaminated fuel system.
Safety & Important Information
- Fuel is flammable. Work in a well-ventilated area away from flames, sparks, and other ignition sources.
- Verify the engine model and serial number and compare the original pump before ordering or installing.
- Do not operate the engine if any fuel connection leaks.
- This is an aftermarket replacement part, not an original Mercury or Mariner component.
- Professional installation by a qualified marine technician is recommended when the fuel-system configuration or fitment is uncertain.
