S.A.F.E. WARNING
SYSTEM
The S.A.F.E. (Speed Adjusting Failsafe Electron-
ics) warn ing system alert s t he oper ator and pro-
tects a gainst engine d amage fro m t he fo llowing
abnormal conditions:
Activation
When one of these conditions occurs, the EMM
interrupts fuel injector and ignition o peration,
reducing engine speed to 1200 RPM. The warning
horn sounds and an Engine Monitor message dis-
plays. When S.A.F.E. is active, the engine will run
normally below 1200 RPM. Above 1200 RPM, the
engine will shake excessively.
Recovery
The engine will operate in S.A.F.E. as long as the
fault condition exists. To recover normal operation,
two conditions must be met:
• Sensor or switch readings must be back with in
limits
• The EMM must be reset—stop and restart
SHUTDOWN MODE
Outboard “sh utdown” will occur if specific fault s
are detected by the EMM.
Conditions that initiate shutdown
Code 57 occurs when the EMM d etects abn or-
mally high RPM relative to the TPS positio n. This
condition could be cause d by u ncontrolled fue l
entering the co mbustion cycle. Before removin g
the code and ST ARTING the outbo ard, find and
repair the cause.
• Perform Fuel System Pressure Test on p. 139.
Check for external fuel leakage that could allow
fuel and/o r vapo r to enter th e engine throug h
the air intake.
• Check for internal fue l le akage from a le aking
injector or vapor separator vent hose.
Recovery
To recover from shu tdown mode, the EMM mus t
NOT detect the re lated fault at start-up. The o ut-
board will not restart u ntil the cause of th e
occurred service co de is resolved (cod e 29 and
31) and the code is cleared using diagnostics soft-
ware (code 3 3 and 5 7). Then, the EMM mus t be
turned OFF and ON again.
IMPORTANT: Shutdown relate d to code 57 or
33 re quires the re moval of th e Occurred serv ice
code. Use Evinrude Diagnostics software to clear
a code 57 or 33.
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 36 Oil injector open circuit (cylinder oil
pump, 3.4 L models only)
Code 38 No oil pressure feedback
Code 40 Cylinder head temperature above
expected range–low speed
Code 43 PORT Cylinder head temperature
above expected range
Code 69 STARBOARD cylinder head tempera-
ture above expected range
Code 70 Cylinder head temperature above
expected range–low speed
Code 29 Excessive EMM temperature
Code 31 Excessive engine temperature
Code 33 Excessive NO OIL condition
Code 57 High RPM with low TPS setting
A WARNING
If t he eng ine sh uts OFF and the “CHECK
ENGINE” ligh t or EMM SENSOR FAULT
LED is flashing, the engine canno t be
restarted. A hazardous fuel condition may
exist which could resul t in a fire or explo-
sion.
