OILING SYSTEM
OIL CONTROL SETTINGS

Oil Recirculation System

External hoses and
der/crankcase passages, and intake manifold pas-
sages are used to recirculate any accumulation of
oil from various locations in the powerhead. The
movement of oil is controlled by check valves.
Cylinder Recirculation
Internal powerhead oil drain passages connect
the intake port areas of the cylinders to circulate
residual oil in the block.
External fittings and in-line check valves on each
side of the cylinder block control the movement of
oil from the lower cylinder port to the upper cylin-
der port.
Crankcase / Main Bearing Recirculation
The movement of oil through the main bearings is
controlled by internal passages, external fittings
and hoses, and check valves.
Lower to upper main bearing oil flow:
•
Lower main bearing cavity to internal crankcase
passage to external fitting, external hoses with
in-line check valve to external fitting at upper
main bearing, and into upper main bearing
through internal crankcase passage.
•
Internal crankcase passage to external fitting in
crankcase cover at upper main bearing, hose
routed to reed plate fitting. This circuit vents the
upper main bearing cavity to promote oil flow.

Oil Priming

The oiling system of the outboard must be primed:
•
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
removed or replaced.
Refer to Oil Supply Priming on p. 56.
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. 55.
Break-in Oiling
The EMM automatically supplies extra oil to the
engine during the first two 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.

IMPORTANT:
The operator must monitor the oil
tank level to confirm oil consumption. This may
require several hours of operation above idle
speed.
