INTERNAL SENSORS
Sensor inp uts and inte rnal EMM contro llers are
used to control outboard operation. Use Evinrude
Diagnostics software to troubleshoot the sensors.
Refer to t he EMM Service Code Chart at the
back of this manual for a comp
engine fault codes.
Internal sensors
are NOT serviceable. Re pro-
gramming or replacement ma y be required to
resolve internal EMM issues.
EMM Temperature Sensor
Monitors the temperature of the fuel injector driver
circuits.
If the EMM temperature exceeds 176°F (80°C) or
the circuit fails, the EMM:
Activates S.A.F.E.
Stores service code 25
EMM LED 4: ON (Running)
Engine Monitor TEMP display: ON
If EMM temp erature excee ds 212°F (100 °C) or
the circuit fails, the EMM:
Activates SHUTDOWN
Stores service code 29
EMM LED 4: FLASHING
Engine Monitor TEMP display: FLASHING
The outboard will not restart until

the en gine co ols be low 2 12°F (1 00°C)and the
EMM temperatu re returns to normal.
SHUTDOWN MODE on p. 62.
If EMM temperature is less tha n -22°F (-30°C) or
the circuit fails, the EMM:
