Diagnostic Procedures
Data Logging
Run the outboard in the water at all speeds. Be
sure to run at any report problem engine speeds
to confirm actual symptoms. Inspection should
include the following:
•
Use the diagnostics software Logging function
to record engine data as a problem is occurring.

Troubleshooting

Outboard will not crank, starter does not
operate:
•
Check condition of battery and cables (main
battery switch and cables). Make sure battery
cables are not reversed.
•
Confirm that switched B+ is present at "A" termi-
nal (purple wire) of starter solenoid with key
switch in the ON position.
•
Refer to Electric Starter Tests on p. 131.
Repair starter or start circuit as needed.
Outboard cranks, will not start:
•
Check emergency stop switch and lanyard
•
Use the Evinrude Diagnostics software Faults
screens to check for current fault codes. If there
are multiple occurred sensor codes, inspect all
5 V sensor circuits for broken or grounded wir-
ing.
•
Perform a Static Ignition test using Evinrude
Diagnostics software and an inductive timing
light. Refer to Ignition System Static Test on
p. 105.
•
If ignition test indicates steady spark, refer to
Fuel System Static Tests on p. 105.

Outboard runs, low on power, misfires:
•
Use the Evinrude Diagnostics software Monitor
screen to check system (55 V) and TPS volt-
ages. System voltage should be steady, and
TPS voltage should be between 0.2 and 4.85 V.
IMPORTANT:
voltage on external circuits only when necessary.
All EMM output currents are DC current.
•
Use the diagnostics software Dynamic Tests to
isolate a faulty cylinder. See Dynamic Tests on
p. 108.
•
Use an inductive timing light to check ignition
and fuel injector circuits. Refer to Running Igni-
tion Tests on p. 122 and Running Fuel Sys-
tem Tests on p. 160.
•
Use the diagnostics software Fuel Control
Adjustment test to help identify a cylinder that
may be too rich or too lean. Refer to Fuel Con-
trol Adjustment on p. 108.
•
Use an inductive amp meter to monitor injector
circuit current. Compare readings of all circuits
to identify possible failure.

•
Check fuel quality and that fuel is present at
injectors.
•
AFTER all the above inspections, if the cause of
a running quality problem still cannot be identi-
fied, perform a compression test to check for
internal powerhead damage.
IMPORTANT:
semble the engine only as a last resort.
Use a digital multimeter to check
Remove a cylinder head or disas-
