S.A.F.E. WARNING
SYSTEM
The EMM activates S.A.F.E. (Speed Adjusting
Failsafe Electronics) and the dash-mounted Sys-
temCheck gauge and horn to alert the operator of
abnormal operating conditions and to prevent
engine damage that could result from:
Loss of oil flow
•
Engine overheat
•
Excessive EMM temperature
•
Excessive or reduced alternator output
•
LOW Oil, sender/switch
•

Initiation

When a sensor or switch provides the EMM with a
specific fault signal, it responds by interrupting
fuel injector and ignition operation. This results in
a gradual reduction in engine RPM until the
engine speed reaches 1200 RPM. The dash-
mounted warning horn sounds and the appropri-
ate SystemCheck light turns on. As long as
S.A.F.E. is activated, the engine will run normally
below 1200 RPM. Above 1200 RPM, the engine
will vibrate excessively.
Conditions that initiate S.A.F.E.
Code 17 Alternator 55 V below expected range
Code 18 Alternator 55 V above expected range
Code 25 EMM temperature above expected
range
Code 34 Oil injector open circuit
Code 38 No oil pressure feedback
Code 43 PORT cylinder head temperature sen-
sor above expected range
Code 69 STARBOARD cylinder head tempera-
ture sensor above expected range

Recovery

The engine will operate in S.A.F.E. as long as the
fault condition exists. To recover from S.A.F.E.,
two conditions must be satisfied: sensor or switch
parameters must be back within limits; and engine
RPM must be reduced to idle. The system will
immediately recover and engine operation will
return to normal.

S.A.F.E. WARNING SYSTEM

SHUTDOWN MODE

Outboard "shutdown" will occur if specific faults
are detected by the EMM.
Conditions that initiate shutdown
Code 29 Excessive EMM temperature
Code 31 Excessive engine temperature
Code 33 Excessive NO OIL condition
Code 57 High RPM with low TPS setting
To recover from shutdown mode, the EMM must
not detect the related fault at start-up. The out-
board will not restart until the cause for the stored
service code is resolved (code 29 and 31) and the
code is cleared using diagnostic software (code
33 and 57); and the EMM is turned OFF and then
ON again.
WARNING
If the engine shuts OFF and the "CHECK
ENGINE" or "CHK ENG" or EMM SENSOR
FAULT LED light is flashing, the engine
cannot be restarted. A hazardous fuel con-
dition may exist which could potentially
result in a fire or explosion.
Shutdown related to code 57 or
IMPORTANT:
33 requires the removal of the stored service
code. Use the Evinrude Diagnostics software pro-
gram to erase a code 57 or 33.
Code 57 occurs when the EMM detects abnor-
mally high RPM relative to the TPS position. This
condition could be caused by uncontrolled fuel
entering the combustion cycle. Before removing
the code and STARTING the outboard, seek out
and repair the cause.
Perform Fuel System Pressure Test on
•
p. 185. Seek out possible external fuel leakage
that could allow fuel and/or vapor to enter the
combustion cycle through the air intake (air
silencer).
Seek out possible internal fuel leakage from a
•
leaking injector and/or vapor separator vent
hose.
