age. A rich or lean running condition or evidence
of internal engine damage could be identified by
the appearance of the spark plugs.

lanyard.
Diagnostic Software Inspections
Before running the outboard, use Evinrude Diag-
nostics software to review historical information
stored in the EMM.
Check the Hard Faults and Stored Faults screens
for current service codes. Correct any problems
and clear the codes before further troubleshoot-
ing. Refer to Stored Service Codes (Faults) on
p. 65.
The stored code screen displays detailed informa-
tion about the operating conditions of the engine
at the time the code was set.
Review information about how the outboard has
been operated using the Profiles screens.
• Check the RPM Profile for long periods of low
speed operation or periods of over-revving rpm.
