FUEL SYSTEM OPERATION
Connecting the Fuel Hose
Connect the fuel hose connector to the hose
from the boat mounted fuel tank.
1. Fuel hose and connector
IMPORTANT: Fuel distribution hoses in the
boat must deliver fuel at the rate of flow need-
ed by the outboard. Minimum inside diameter
of fuel hoses must be 3/8 in. (9 mm).
Fuel systems with built-in tanks, particularly
those that include antisiphon valves and filter/
primer units, may have restrictions that pre-
vent the engine fuel pump from delivering
enough fuel under all conditions. This can re-
sult in a loss of performance.
FUEL SYSTEM PRIMING
FUEL SELECTOR SWITCH
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.
To use jet fuel, or kerosene, press the fuel se-
lector 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 is an emergency fuel
ONLY . If diesel must be used, the fuel selec-
tor switch should be in the Heavy Fuel posi-
tion.
WARNING
Store fuel tanks in a well-ventilated
area, away from heat and open flame.
Prevent escape of liquid or vapors
which could accidentally ignite.
If the outboard is run out of fuel, refill the fuel
tank and squeeze the primer bulb until firm.
The high pressure fuel circuits and injectors
will prime as the outboard is cranked with the
starter.

CAUTION
Operation with the fuel selector switch
in the wrong position could cause
internal engine damage not covered by
the outboard’s limited warranty.
