can be used for troubleshooting, for checking
parts information, and for making adjustments to
the system.
Use Evinrude Diagnostics software, P/N 764642,
and a laptop computer to access program infor-
mation.
For software help, refer to the
IMPORTANT:
"Help" menu in the software.

directly to the computer's serial port.
The EMM must turn ON before it will communicate
with any outside device. Power is normally sup-
plied to the EMM when the key switch is ON.
Switched B+ (12 V) is supplied to the engine wire
harness. Current enters the EMM at pin 21 (pur-
ple) of the EMM J1-B connector.
The EMM is also turned ON when it begins to
receive AC voltage from the stator while the out-
board is being cranked.
