Engine oil level check
1. Check:
Engine oil level
Checking steps:
CAUTION:
When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, or obstacles. The
water current or wind can cause the
watercraft to move and lead to a colli-
sion.
When checking the engine oil level on
land, supply water to the cooling water
passages.
Make sure that engine has enough oil
but do not overfill. If there is too little
oil, the engine can be damaged. If there
is too much oil, the air filter can
become saturated with oil, perma-
nently damaging the filter and reduc-
ing engine performance. Follow the
checking procedure carefully.
Make sure that debris or water does
not enter the oil tank filler hole. Debris
or water in the engine oil can cause
serious engine damage.

Place the watercraft in a horizontal posi-
tion or launch the watercraft.
Remove the seat.
Remove the oil tank filler cap 1
and
check for oil on the dipstick 2
.
If there is no oil on the dipstick, pour
enough oil so that the tip of the dipstick
comes into contact with the oil, and then
install the filler cap.
Start the engine.
CAUTION:
When starting the engine make sure the
dipstick is securely fitted into the oil
tank.
NOTE:
The engine cannot be started if the
Yamaha Security System is in the lock
mode. (Deluxe model only)
For information on the Yamaha Security
System, see the owner’s manual. (Deluxe
model only)
Run the engine at trolling speed for 6
minutes or more, and then turn the
engine off.
CAUTION:
When checking the oil level on land, be
sure to connect a garden hose to the
watercraft for proper water supply.
NOTE:
If the ambient temperature is 20°C (68°F)
or less, warm up the engine for an addi-
tional 5 minutes.
Remove the oil tank filler cap 1
, wipe the
dipstick 2
clean, and then screw the filler
cap into the filler hole completely.

Remove the oil tank filler cap again and
check that the oil level is between the
minimum level mark a
and maximum
level mark b
on the dipstick.
If the engine oil is below the minimum
level mark b
, add sufficient oil of the rec-
ommended type to raise it to the correct
level.
If the engine oil is above the maximum
level mark a
, extract sufficient oil using
an oil changer to lower it to the correct
level.
NOTE:
If the oil temperature is low, the reading on
the dipstick will be low, and if the tempera-
ture is high, the reading on the dipstick will
be high.
Engine oil change — using oil changer
WARNING
Avoid changing the engine oil immediately
after turning the engine off. The oil is hot
and should be handled with care to avoid
burns.
CAUTION:
Do not run the engine with too much or
not enough oil in the oil tank. Oil could
spray out or the engine could be dam-
aged.
Do not run the engine for more than 15
seconds without supplying water, when
checking the oil level on land.
The engine could overheat.
Be sure to change the engine oil after the
first 10 hours of operation, and every 100
hours thereafter or at the start of a new
season, otherwise the engine will wear
quickly.
1. Warm the engine up, and then put the
watercraft in a horizontal position.
