Troubleshooting & FAQ
How do I confirm this fuel pump is correct for my engine?
Match your engine brand, horsepower, four-stroke configuration, exact model, year, and serial-number range against the engine service information. Also compare the original pump’s mounting arrangement, hose connections, and manufacturer reference number with the information listed above.
What are common signs of a failing fuel pump?
Possible symptoms include hard starting, stalling, loss of power, sputtering at higher speed, or failure to start. These symptoms can also result from restricted fuel filters, damaged fuel lines, contaminated fuel, ignition faults, or other fuel-system problems, so diagnose the complete system before replacing the pump.
Is this a direct replacement for both Yamaha and Mercury pumps?
This listing is an aftermarket replacement associated with the specified Mercury and Yamaha reference numbers. Exact interchangeability depends on the engine model and application. Confirm the manufacturer reference number and physical configuration before installation.
What maintenance is required for this fuel pump?
The pump itself is not normally serviced as a routine maintenance item. Use clean, fresh fuel, keep the fuel system clean, and replace filters at the intervals specified for your engine. Inspect hoses, clamps, and connections regularly.
Is this an OEM part?
No. This is an aftermarket replacement component and is not manufactured or branded by Mercury Marine or Yamaha Marine. The manufacturer reference numbers are used only for application and cross-reference identification.
What warranty is included?
The replacement is covered by a 1-year aftermarket warranty against manufacturing defects under normal use. Warranty coverage does not generally include incorrect installation, misuse, contamination, modification, or normal wear. Contact support with your order information if assistance is required.
