SYSTEM ANALYSIS
DIAGNOSTIC PROCEDURES
5
• Check the Engine Temperature Profile for evi-
dence of cold running or overheating.
• Check the Knock Profile for high knock levels.
High knock levels may be due to high operating
temperatures, incorrect ignition timing, poor-
quality fuel, or a loose knock sensor.
• The Last Two Minutes profile reports engine
run-time values during the last two minutes of
operation above 1500 rpm. Information is col-
lected once per second. The newest record is
first on the list. As each new record is added,
the oldest record is removed.
The Engine Identity Report provides a snap-shot
of current engine and sensor conditions. From the
Identity screen, press the Print button. Next, press
Print to Printer to print, or Print to PDF to save the
report.
Operational Inspections
Run the outboard to confirm actual symptoms
before performing any unnecessary procedures.
Inspection should include the following:
• Make sure the outboard can be cranked easily,
with no mechanical binding.
• Check the EMM LED Indicators for system sta-
tus information. Refer to EMM LED INDICA-
TORS on p. 78.
