Engine oil level
Check the engine oil level before each
use.
CAUTION:@
When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and 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. (See page 4-1 for proce-
dures on supplying water.)

Make sure that the engine has enough
oil but do not overfill it. 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 and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause seri-
ous engine damage.
@
To check the engine oil level:
1. Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine.
2. Run the engine at trolling speed for
6 minutes or more, and then stop the
engine.
NOTE:@ If the ambient temperature is 20 °C (68°F)
or less, warm up the engine for an additional
5 minutes.
@
3. Remove the seat. (See page 2-5 for seat
removal and installation procedures.)

Capsized watercraft
If the watercraft capsizes, turn it over
immediately.
Be sure to carefully follow the procedures
below to prevent injury or damage to the
watercraft.
WARNING@ IMPROPER UPRIGHTING CAN CAUSE
INJURY:

Make sure that the engine shut-off
cord is removed from the engine shut-
off switch.

Do not put your hands in the intake
grate.

Watch so you are not hit by the water-
craft as it comes over.
@
CAUTION:@ If the watercraft capsizes, release the
throttle lever immediately. Oil could flow
into the air filter case and the engine
could be damaged.
@
1. Remove the clip from the engine shut-off
switch.
2. Swim to the rear of the watercraft. Pull
the watercraft over with your left hand on
the ride plate while pushing down on the
gunwale with your right hand or foot.
NOTE:@ If the port (left) side of the capsized water-
craft is tilting up, push down on the gunwale
so that the port (left) side is down before
turning the watercraft clockwise.
@
CAUTION:@ Do not turn the watercraft over counter-
clockwise, otherwise water can leak into
the engine, which can result in severe
damage.

Checking the air filter element
Have a Yamaha dealer check and clean
or replace the air filter element every
12 months or every 100 hours of operation.
EJU18891
Inspecting the jet thrust nozzle
angle
Check for smooth operation of the handle-
bars and jet thrust nozzle.
Turn the handlebars as far as possible to
the right and left and check that the differ-
ence of distances A and B between the jet
thrust nozzle and the nozzle is within specifi-
cation.
If steering is stiff or misadjusted, have a
Yamaha dealer service it.
EJU21290
Inspecting the shift cable
(for VX110 Deluxe)
Place the shift lever in the reverse posi-
tion.
Make sure that the reverse gate makes
contact with the stopper 1.
If the reverse gate does not make contact
with the stopper, have a Yamaha dealer ser-
vice it. Difference of A and B:
Maximum 5 mm (0.20 in)
