Using The Evinrude MFE Outboard
FUEL SYSTEM OPERATION
IMPORTANT: The minimum inside diameter
of the fuel hose from the fuel tank to the out-
board must be 3/8 in. (9 mm). Be sure the
boat’s fuel system provides adequate fuel to
the outboard. Fuel systems with anti-siphon
valves, filters or primer units may restrict fuel
flow to the outboard and effect engine perfor-
mance.
FUEL SYSTEM PRIMING
If the outboard is run out of fuel, refill the fuel
tank and squeeze the primer bulb until firm.
Prime the electric fuel pump by first removing
the engine cut–off switch clip and then pulling
the rope at least two times. This will cause the
fuel pump to fill the injectors. Replace the en-
gine cut–off switch clip and follow the normal
starting procedure.
FUEL SELECTOR SWITCH
Operation with the fuel selec-
tor switch in the wrong position could
cause internal engine damage not cov-
ered by the outboard’s limited warranty
The Engine Management Module ( EMM ) in-
cludes programs allowing the engine to run on
several types of fuel. You MUST select the
correct program for the fuel being used. Refer
to Fuel Requirements on p. 13.
• To use jet fuel, or kerosene, press the fuel
selector switch IN .
• To use gasoline, pull the fuel selector switch
OUT to expose the red indicator ring.
When switching from one fuel to another:
• Connect the fuel supply hose to the desired
fuel supply.
• Adjust the selector switch on the port side of
the outboard for the new fuel.
• Restart the engine to reset the EMM —
changing the switch has no effect while the
engine is running.
• The EMM calculates when the previous fuel
remaining in the engine has been used and
switches the program at that time.
• The engine may run noticeably rough during
the transition period.
IMPORTANT: Diesel fuel should be used as
an emergency fuel ONLY. If diesel fuel must
be used, the fuel selector switch should be in
the Heavy Fuel position. Refer to Emergency
Fuel on p. 13 and De-Carboning Procedure
on p. 38.
A
WARNING
If engine is equipped with a quick-dis-
connect fuel hose, you MUST discon-
nect the fuel hose from the engine and
the fuel tank to prevent fuel leaks:
• Whenever the engine is NOT being
used
• Whenever the engine is being trailered
• Whenever the engine is in storage
NOTE: A small amount of fuel may be
released when the fuel connector is dis-
connected.
Store portable fuel tanks in well-venti-
lated areas, away from heat sources and
open flames. Close the vent screw of the
fuel tank cap, if equipped, to prevent
escape of fuel or fuel vapors which
could accidentally ignite. Do not allow
disconnected fuel hoses to leak fuel.
