Engine Management
Module (EMM)
The Engine Management Module (EMM) is a
water-cooled controller. It controls engine man-
agement and engine–related remote control func-
tions.
This section discusses the functions of the EMM
and its various internal and external sensors. It
also describes using Evinrude Diagnostics soft-
ware to retrieve and adjust service information
saved in the EMM.
EMM Functions
The EMM controls the following processes and
functions:
• Alternator output; 55 V and 12 V
• Start Assist Circuit (SAC) voltage boost
• Fuel and ignition timing and duration
• Fuel injector activation
• Oil pump activation
• Electric fuel lift pump control
• Electric high pressure fuel pump control
• Idle speed control
• RPM limiter
• Electrical circuit monitoring
• Fault code creation and storage
• Warning system activation
• ROM verification, self-test
• Cold starting
• Output of diagnostic data
• Tachometer signal
• RPM profile and engine hours
• Oil pump activation
• Anti-knock compensation
• Electronic throttle control
• Electronic shift control
• Dynamic Power Steering
EMM Connections
IMPORTANT: EMM connections and wiring
must be clean and tight. Improper electrical con-
nections can damage the EMM. DO NOT run the
outboard with loose or disconnected wiring.
Make sure EMM connections are clean and tight.
• Engine wire harness to EMM connectors; J1-A,
J1-B, J2, J3, J4.
• Stator to EMM connections; one 6-pin AMP and
J2 connector.
