ENGINE MONITOR
SYSTEM
All remote controlled outboards must be equipped
with an engine monitoring syste m to warn the
operator of conditions that could damage the out-
board.
The eng ine monitor system includes sensors on
the outboard and oil tank, a warning horn, a dash-
mounted display, and related wiring.
The outb oard’s
EMM
sen ds information about
monitored functions to:
•
SystemCheck
gauges
•
An
I-Command
or
ICON
display
•
EMM
LED indicators.
IMPORTANT:
Operating the outboa rd without
an engine monito r will void the warranty for fail-
ures related t o monitored functions. For informa-
tion about bo at mount ed Information Displa y
System o ptions, refer to th e curren t
Predelivery
and Installation Guide
included with the se rvice
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 ind icates 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 th is manual for a co mplete list of all fault
codes.
System Self-Test
During engine start-up, pause with the key switch
in the ON position. The horn se lf-tests by sound-
ing a ha lf-second beep .
SystemCheck
g auges
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 ho rn will no t sound.
Refer to
SystemCheck CIRCUIT TESTS
on
p. 107.
Engine Running
All warning circuits are active wh en the eng ine is
running. Th e horn circu it is active when engin e
speed exceeds 500 RPM.
Engine monitor warnings activate the horn for 1 0
seconds and the appro priate gauge light for a
minimum of 30 secon ds. If the failure is mome n-
tary (for example, oil moving in the tank), the light
will remain ON for t he full 30 seconds befo re
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.
