Crankcase / Main Bearing Recirculation
The movement of oil through the main bearings is
controlled by internal passages, external fittings
and hoses, and an in-line check valve.
Both center main bearings receive oil through
grooved passages in the crankcase. Oil migrates
to the bearings from the crankcase areas of the
higher cylinders.
The lower main bearing receives oil through a
grooved passage in the crankcase.
Lower to upper main bearing oil flow
Lower main bearing cavity through internal crank-
case passage to external fitting, external hoses
with in-line check valve to external fitting at upper

Oil Priming

The oiling system of the outboard must be primed:
3
When the outboard is first installed.
•
Whenever the oil supply to the oil lift pump is
•
disconnected or disrupted.
Whenever an oiling system component is
•
4
removed or replaced.
Refer to Oil Supply Priming on p. 59.

Oiling Rates

EMM programming controls the rate of oil injection
based on engine RPM. This rate can be adjusted
for the grade of oil being used, and also for power-

head break-in. Use Evinrude Diagnostics software
to access these features.
Refer to Oil Injection Rate on p. 58.

Break-in Oiling

The EMM automatically supplies extra oil to the
engine during the first five hours of operation,
above 2000 RPM.
Use Evinrude Diagnostics software to make
•
sure the break-in program has been started on
a new outboard.
Use the diagnostics software to start break-in
•
oiling after a powerhead rebuild.
