Changing engine oil
WARNING
EWM00761
Avoid draining the engine oil immedi-
ately after stopping the engine. The oil
is hot and should be handled with care
to avoid burns.
Be sure the outboard motor is securely
fastened to the transom or a stable
stand.
NOTICE
ECM01711
Change the engine oil after the first 20
hours of operation or 3 months, and ev-
ery 100 hours or at 1-year intervals there-
after. Otherwise the engine will wear
quickly.
To prevent spilling oil where it could cause
damage to nature, it is strongly recommend-
ed that you use an oil changer to change the
engine oil. If an oil changer is not available,
drain the engine oil by removing the drain
screw. If you are not familiar with the proce-
dure for changing the engine oil, consult your
Yamaha dealer.
Changing the engine oil using an oil changer
(recommended)
1. Put the outboard motor in an upright po-
sition (not tilted).
NOTICE:
If the out-
board motor is not level, the oil level
indicated on the oil dipstick may not
be accurate.
