SERVICING YOUR OUTBOARD MOTOR
When you check the oil level in the oil level inspection window, you might
notice the engine oil appears milky or the oil level has increased. If you notice
either condition, change the engine oil. See the following table for an
explanation of these conditions.
Operating Method Result Effect
Running the engine below
3,000
rpm for more than
30% of the time so the
engine does not warm up.
• Water condenses in the
engine and mixes with the
oil, resulting in a milky
appearance.
The engine oil deteriorates,
becomes less efficient as a
lubricant, and causes an
engine malfunction.
Frequent starting and stop-
ping without allowing the
en
gine to warm up.
• Unburned fuel mixes with
the oil, increasing the vol-
ume of oil.
Engine Oil Change
An engine oil evacuation device may
be used to remove the engine oil, if
you do not wish to remove the
outboard from the boat.
Drain the used oil while the engine is
warm. W
arm oil drains quickly and
completely.
1. Move the fuel valve lever to the
OF
F position, and turn the vent
knob OFF position to close the fuel
vent.
2. Remove the outboard from the
bo
at.
3. Loosen the oil drain screw, and turn
the outboard motor on its ti
ller
handle side.
4. Remove the oil drain screw and
w
asher to drain the oil.
