FUEL AND OIL SYSTEMS
Routine replacement of filters reduces the possi-
bility 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 40–90 HP outboards are
equipped with an in-line fuel filter. Refer to FUEL
COMPONENT SERVICING on p. 146.
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 maximizes air flow while minimiz-
ing noise.
Routine cleaning of the air silencer is recom-
mended 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.

A WARNING
Failure to check for fuel leakage could
allow a leak to go undetected, resulting in
fire or explosion.
