OILING SYSTEM TESTS
OILING SYSTEM TESTS
IMPORTANT: Always perform visual inspections
to identify oiling system leaks. Make sure the oil
tank is filled and oil supply is not contaminated.
Oil Injection Pump Static Test
IMPORTANT: Static tests are performed with
the outboard not running.
Use the Evinrude Diagnostics Software program
to activate Oil Injection Pump test. This initiates
the EMM control function for the oil injection
pump.
Oil injection pump should activate with key switch
in the ON position.
The EMM provides ground to pin 2 (blue wire) of
oil injection pump electrical connector. Refer to
Oil Injection Pump Voltage Test on p. 218.
Oil Injection Pump Voltage Test
Acceptable voltage readings:
• Key switch ON: approximately 30 V
• Outboard running: 55 V
STEP 1
Check voltage at pin 1 (white/red wire) of oil injec-
tion pump electrical connector with key switch ON.
Results:
• Approximately 30 V is acceptable with outboard
not running. See Oil Injection Pump Circuit
Resistance Test on p. 219.
• No voltage reading, proceed to STEP 2.
STEP 2
Run outboard. Check system voltage using diag-
nostic software program. The alternator/system
output wires (white/red) are terminals 19 and 29 of
the EMM J2 connector. If needed, use Electrical
Test Probe Kit, P/N 342677, and a multimeter set
to read 55 VDC to check engine harness voltage
readings.
Results:
• Proper voltage reading, inspect connections
and wiring. Replace faulty wire harness or con-
nector.
• No or low voltage, check connections from
EMM and stator to engine wire harness. Repair
faulty connection or refer to STATOR TESTS
on p. 141 for testing procedures.
STEP 3
Use Electrical Test Probe Kit, P/N 342677, and a
multimeter set to read 55 VDC. Check voltage at
