ENGINE MONITOR
SYSTEM
All remote controlled outboards must be equipped
with an engine monitoring system to warn the
operator of conditions that could damage the out-
board.
The engine monitor system includes sensors on
the outboard and oil tank, a warning horn, a dash-
mounted display, and related wiring.
The outboard’s EMM sends information about
monitored functions to:
•
SystemCheck gauges
•
An I-Command or ICON display
•
EMM LED indicators.
IMPORTANT:
Operating the outboard without
an engine monitor will void the warranty for fail-
ures related to monitored functions. For informa-
tion about boat mounted Information Display
System options, refer to the current
Predelivery
and Installation Guide included with the service
manual set.
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.
•
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.
Note: The warning horn does NOT sound in an
I-Command installation.
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. 111.
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.
