Troubleshooting & FAQ

Q: How do I confirm this fuel pump fits my Johnson or Evinrude engine?
A: Cross-reference your engine's model, HP, and year with the compatibility table above. You can also check your existing pump for one of the OEM part numbers listed (397839, 391638, 395091, 397274) or consult the Johnson serial number guide linked in the Compatible Engine Models section.

Q: What are the signs that my fuel pump is failing?
A: Common symptoms include difficulty starting, engine stalling or sputtering under load, loss of power at higher RPMs, and visible fuel leaks around the pump body. If you notice any of these issues, inspect the pump diaphragm and gasket for wear or damage.

Q: How often should I replace the fuel pump on my outboard?
A: Fuel pumps typically last several seasons, but replacement intervals depend on usage and fuel quality. Inspect the pump annually for cracks, leaks, or diaphragm deterioration, and replace it if performance issues arise or every 3–5 years as preventive maintenance.

Q: Can I install this fuel pump myself, or do I need a marine mechanic?
A: Installation is straightforward for those with basic mechanical skills and tools. However, ensuring proper gasket sealing and correct actuating-arm alignment is critical. If you're unfamiliar with outboard fuel systems, professional installation is recommended.

Q: Does this pump work with both premix and oil-injected Johnson/Evinrude engines?
