ENGINE MONITORING
SYSTEM
The engine monitoring system warns the operator
of conditions that could damage the outboard. The
system includes sensors on the engine and oil
tank, a warning horn, a dash-mounted gauge, and
related wiring.
The EMM sends information about monitored
functions to:
• An I-Command, or other NMEA 2000
compliant
CANbus network
• The SystemCheck Modular Wiring System
(MWS)
• EMM LED indicators
IMPORTANT: Outboards with remote controls
must be equipped with an I-Command system, a
SystemCheck gauge, or an equivalent engine
monitor. Operating the outboard without an engine
monitor will void the warranty for failures related to
monitored functions.
The EMM activates the warning horn and gauge
displays as follows:
• LOW OIL means that oil in the tank is at reserve
level (about 1/4 full).
• NO OIL indicates the oil tank is empty, or the oil
system is damaged.
• WATER TEMP or HOT indicates an engine or
EMM overheat condition.
• CHECK ENGINE or FAULT is used to indicate
other fault conditions identified by the EMM.
Refer to the EMM Service Code Chart at the
back of this manual for a complete list of all fault
codes.
System Self-Test
During engine start-up, pause with the key switch
in the ON position. The horn self-tests by sound-
ing a half-second beep. SystemCheck gauges
self-test by turning the indicator lights on simulta-
neously, then off in sequence.
Service Mode
SystemCheck goes into a service mode if the key
is left ON after self-test (engine NOT running). All
light circuits and sensors are active, but the horn
is not. Grounding the appropriate light circuit wire
will turn the light on, but the horn will not sound.
Refer to SystemCheck CIRCUIT TESTS on
p. 148.
Engine Running
All warning circuits are active when the engine is
running. The horn circuit is active when engine
speed exceeds 500 RPM.
Engine monitor warnings activate the horn for 10
seconds and the appropriate gauge light for a
minimum of 30 seconds. If the failure is momen-
tary (for example, oil moving in the tank), the light
will remain ON for the full 30 seconds before
going out. If the fault continues, the light remains
ON until the key is turned OFF or the failure is cor-
rected. The warning will reoccur at the next start-
up if the problem is not corrected.
