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 (yellow/red wire) of starter solenoid with key
switch in the START position.
Check ground at “B” terminal harness connec-
tion.
Refer to ELECTRIC START TESTS on p. 106.
Repair starter or start circuit as needed.
Outboard cranks, will not start:
Check emergency stop switch and lanyard
Check powerhead mounted neutral switch
Check the EMM LED Indicators for system sta-
tus information. Refer to EMM LED INDICA-
TORS on p. 81.
Use the Evinrude Diagnostics software
Occurred Faults screen to check for current ser-
vice codes. If there are multiple occurred sensor
codes, inspect all 5 V sensor circuits for broken
or grounded wiring.
Perform a Static Ignition test using Evinrude
Diagnostics software and an inductive timing
light. Refer to Static Ignition Test on p. 85.
If ignition test indicates steady spark, refer to
FUEL DELIVERY TESTS on p. 88.
Outboard runs, low on power, misfires:
Check the EMM LED Indicators for system sta-
tus information. Refer to EMM LED INDICA-
TORS on p. 81.
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: Use a digital multimeter to check
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. 80.
Use an inductive timing light to check ignition
and fuel injector circuits. Refer to Running Igni-
tion Tests on p. 86 and Running Fuel System
Tests on p. 89.
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. 80.
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.
Use the diagnostics software Logging function
to record engine data as a problem is occurring.
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: Remove a cylinder head or disas-
semble the engine only as a last resort.
