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 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.

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. 59.

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.

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.

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