Recommended Lubricants
Evinrude/Johnson XD100, XD50, or XD30 outboard oils are recommended for use in Evinrude E-TEC outboards. If these oils are not available, you must use a TC-W3 certified oil.
Evinrude/Johnson XD100 outboard oil is highly recommended for all conditions and applications.
Engine Lubricant Below 32°F (0°C)
If the outboard will be operated in temperatures below freezing (32°F, 0°C), use Evinrude/Johnson XD100.
IMPORTANT: For new outboards, test low oil warning before filling oil tank.
Turn key switch to ON. The engine monitor warning display should show “LOW OIL.”
Add enough oil to raise level to at least one-quarter capacity.
The “LOW OIL” warning should not display.
Failure to follow these recommendations could void the outboard warranty if a lubrication-related failure occurs.
COMPONENTS
The oiling system consists of the following components:
● Oil tank
● Oil injection pump and manifold assembly
● Rear oil manifold assembly
● Oil pressure sensor
● Electrical circuit
● LOW OIL and NO OIL warning systems
● Cylinder and crankcase
● Oil recirculation system
Oil Tank Assembly
The oil tank must be properly positioned and the oil level must be monitored. Refer to the Predelivery and Installation Guide.
Oil Tank Components:
● Tank, 1.8 or 3.0 gallon capacity
● Oil pickup and filter assembly
● LOW OIL sending unit
● Mounting bracket and hardware
● Protective cover (1.8 gallon tank only)
● Primer bulb and supply hose.

Oil Injection Pump
The oil injection pump is an electric (55 V) actuator style pump. It draws oil from the oil tank through the oil supply hose (25 ft. [7.6 m] maximum) and supplies pressurized oil to the oil manifold. The EMM supplies 55 V and controls activation of the pump.
Oil injection pump
Oil manifold
The oil manifold distributes the oil supplied by the oil injection pump to the crankcase and to the rear oil manifold.
Oil Pressure Sensor
The oil pressure sensor reacts to changes in oil manifold pressure. The EMM supplies and monitors electrical current to the sensor.
- Oil pressure sensor
The sensor provides an output voltage to the EMM based on oil manifold pressures.
● 5 VDC Input on RED wire
● 0.5 - 4.5 V Output on TAN / WHITE wire
● Ground on BLACK wire
The EMM monitors the oil pressure sensor’s electrical circuit. If circuit voltage is beyond the specified range (< 0.15 V, > 4.85 V), the EMM:
| Stores service code 71 |
|---|
| EMM LED 3: ON (Running) |
If oil pressure is below expected range (< 0.4 V), the EMM:
| Stores service code 72 |
|---|
| EMM LED 3: ON (Running) |
If oil pressure is above expected range (> 4.6 V), the EMM:
| Stores service code 73 |
|---|
| EMM LED 3: ON (Running) |
Refer to Oil Pressure Sensor on p. 57.
Rear Oil Manifold
The rear oil manifold receives oil from the primary manifold and distributes it to the cylinder sleeves.
- Rear oil manifold
Electrical Circuit (55 V)
The oil injector is powered by the 55 V electrical circuit. The EMM controls pump operation by rapidly connecting and disconnecting the pump’s internal coil to ground.
The EMM monitors the oil injection pump electrical circuit. If circuit voltage is beyond the specified range (open circuit), the EMM:
| Activates S.A.F.E |
|---|
| Stores service code 34 |
| EMM LED 4: ON (Running) |
| Engine Monitor NO OIL display: ON |
LOW OIL Warning
A sending unit in the oil tank pick-up assembly monitors the oil level in the oil tank.
If the oil level falls below one-quarter capacity, the EMM signals:
| Engine Monitor LOW OIL display: ON |
|---|
An optional oil tank sending unit kit is available to display actual oil level through an I-Command network.
NO OIL Warning
The EMM monitors the electrical circuit of the oil pressure sensor. If the sensor or circuit fails, or if there is a lack of oil pressure in the oil distribution manifold, the EMM:
| Activates S.A.F.E. |
|---|
| Stores service code 38 |
| EMM LED 4: ON (Running) |
| Engine Monitor NO OIL display: ON |
Cylinder and Crankcase
The primary oil distribution manifold provides crankcase lubrication through oil distribution hoses and pressed-in fittings at the front of the crankcase, port side.
- Pressed-in fittings
The rear oil distribution manifold provides lubrication for each cylinder. Each cylinder of the cylinder/crankcase has a pressed-in fitting which is connected to an oil distribution hose.
- Rear oil manifold
Oil Recirculation System
External hoses and fittings, internal cylinder/crankcase passages, and intake manifold passages 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 cylinder 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.
Oil moves from the crankcase areas of the higher cylinders through grooved passages in the crankcase to the center and lower main bearings. Additional oil moves through intake manifold passages to the crankcase and lower main bearing.
Lower to upper main bearing oil flow:
Oil moves from the lower main bearing cavity to an external hose with in-line check valve and to the upper main bearing. Additional oil from the rear oil manifold is supplied to this oil circuit on V6 models.
Oil moves from Intake manifold passages to external check valve fittings and hoses and to the upper main bearing.
