FUEL SYSTEM
COMPONENTS
Fuel Manifold
The vapor separator uses molded internal pas-
sages to route fuel directly to and from the injec-
tors. Refer to
Fuel Injectors
Fuel injectors are fuel metering, electric solenoids
(55 V) bolted directly to the cylinder head. The
EMM
controls the activation of each injector by
rapidly connecting and disconnecting the injec-
tor’s internal coil to ground.
Fuel Flow Compensation
The flow rate of each injector is measured as part
of the manufacturing process. This information is
recorded and assigned to the injector by serial
number.
The
EMM
is programmed to compensate for vari-
ations in fuel flow. Each injector and its location on
the outboard is identified by the
EMM
. DO NOT
install an injector without updating the compensa-
tion software.
Each service injector includes its fuel flow infor-
mation on a 3.5 in. floppy disk. This software
allows the
EMM
to be reprogrammed for this injec-
tor’s unique fuel flow characteristics.
Fuel injectors MUST NOT be moved
from one cylinder to another. EMM program-
ming is associated with the cylinder location
of each injector. Installing an injector on the
wrong cylinder can result in powerhead fail-
ure.
Injector Fuel Supply
Fuel is supplied to the injectors by the fuel circula-
tion pump and the fuel supply manifold.
Each injector has internal fuel passages. These
passages are designed to:
•
Provide fuel to the injector's injection chamber
•
Route fuel through the injector housing to cool
the injector coil and armature
