FUEL AND OIL SYSTEMS
Routine replacement of filters reduces the possibility of foreign material restricting the incoming fuel or oil supplies.
Replacement filter elements are available through Evinrude/Johnson Genuine Parts.
Fuel Filter
Evinrude E-TEC 25–30 HP outboards are equipped with an in-line fuel filter. Refer to FUEL COMPONENT SERVICING on p. 158.

Oil Filters and Oil Reservoir
Perform visual inspections to identify oiling system leaks. Make certain the oil tank is filled and oil supply is not contaminated.
Air Silencer
The air silencer on Evinrude outboards maximizes air flow while minimizing noise.
Routine cleaning of the air silencer is recommended to remove any accumulation of debris.
Hoses and Connections
Check condition of all hoses and connections in both the fuel and oil systems:
- Visually inspect all components.
- Observe all clamps, hoses, and connections while outboard is running.
- Replace all damaged components.
- Repair all leaks.
Failure to check for fuel leakage could allow a leak to go undetected, resulting in fire or explosion.
