CAUTION:

●
Do not overfill the oil, and be sure the
outboard motor is upright (not tilted)
when checking and changing the en-
gine oil.
●
If the oil level is above the upper level
mark, drain until the level meets the
specified capacity. Overfilling the oil
could cause leakage or damage.
CAUTION:
ECM01240
Change the engine oil after the first 10
hours of operation, and every 100 hours
or at 6-month intervals thereafter. Other-
wise the engine will wear quickly.
NOTE:
Change the engine oil when the oil is still
warm.
1. Put the outboard motor in an upright po-
sition (not tilted).
2. Prepare a suitable container that holds a
larger amount than the engine oil capac-
ity. Loosen and remove the drain screw
while holding the container under the
drain hole. Then remove the oil filler cap.
Let the oil drain completely. Wipe up any
spilled oil immediately.
3. Put a new gasket on the oil drain screw.
Apply a light coat of oil to the gasket and
install the drain screw.
NOTE:
If a torque wrench is not available when you
are installing the drain screw, finger tighten
the screw just until the gasket comes into
contact with the surface of the drain hole.
Then tighten 1/4 to 1/2 turn more. Tighten
the drain screw to the correct torque with a
torque wrench as soon as possible.
4. Add the correct amount of oil through the
filler hole. Install the filler cap.
