• Voltage at pin A should be approximately 55 V.
• If voltage at pin A is within range, refer to Oil
Injection Pump Resistance Test on p. 173.
• No voltage reading at pin A, refer to System
Voltage Test on p. 86.
Oil Injection Pump Resistance
Test
Disconnect the battery cables at the battery.
Disconnect the electrical connector from the oil
injection pump.
Use a digital multimeter to measure the resistance
between the pins of the oil injection pump connec-
tor. Calibrate the meter to the LOW OHMS scale.
Results:
• An infinite reading (∞) indicates an open circuit
of the injection pump winding. Replace faulty
pump.
Oil Injection Pump Function Test
Remove oil distribution hose from fitting at oil dis-
tribution manifold. Do not lose the brass hose sup-
port.
Clean up any spilled oil with shop towels.
Temporarily install a length of oil hose.
Start the outboard and observe oil flow:
• Oil flows from hose, compare to oil flow at other
distribution fittings
• If one or more fittings fail to flow oil, replace the
oil injection pump assembly.
Reinstall hose into manifold.
IMPORTANT: Make sure hose support is in hose
and hose is fully inserted into manifold. Refer to Oil
Distribution Hoses on p. 174.

ENVIRONMENTAL NOTE
Dispose of used oil or oil contaminated towels in
an environmentally responsible manner, or
according to local regulations.
