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.
@
Checking 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 rear and front seats. (See
pages 2-5 and 2-6 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.

Changing the engine oil
WARNING@ Engine oil is extremely hot immediately
after the engine is turned off. Coming
into contact with or getting any engine
oil on your clothes could result in burns.
@
CAUTION:@
Do not run the engine with too much or
not enough oil in the oil tank. Oil could
spray out and the engine could be
damaged.

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.
The oil filter should be replaced every
year or every 100 hours of operation.
Have a Yamaha dealer replace the oil
filter if necessary.
@
It is recommended to have a Yamaha
dealer change the engine oil. However, if
you choose to change the oil on your own,
consult a Yamaha dealer.
NOTE:@ Dispose of used oil according to local regu-
lations.
@
Recommended engine oil:
See page 3-3.
Oil quantity:
With oil filter replacement:
2.2 L (2.3 US qt, 1.9 Imp qt)
Without oil filter replacement:
2.0 L (2.1 US qt, 1.8 Imp qt)
Total amount:
4.3 L (4.5 US qt, 3.8 Imp qt)

Checking the air filter element
The air filter element should be checked
every 12 months or every 100 hours of oper-
ation.
To check the air filter:
1. Remove the rear and front seats. (See
pages 2-5 and 2-6 for seat removal and
installation procedures.)
2. Remove the air filter case cover
screws1, slide the locks 2 open, and
then remove the case cover.
3. Remove the air filter element and check
it for dirt and oil. Replace the air filter ele-
ment if there is any oil buildup, or every
2 years or every 200 hours of operation.
4. Install the air filter element in the air filter
case, and then install the case cover.
CAUTION:@
Make sure that the air filter element is
installed in the filter case properly.

Do not start the engine with the air fil-
ter element removed, otherwise the
pistons and cylinders could be dam-
aged.

If cleaning the air filter element, use
cold or lukewarm water and let it air
dry completely. Do not use detergent
or solvent to clean the air filter ele-
ment, or dry it with heat or com-
pressed air, otherwise it could be
damaged.

Cleaning and adjusting the
spark plugs
The spark plug is an important engine
component and is easy to inspect. The con-
dition of the spark plug can indicate some-
thing about the condition of the engine. For
example, if one spark plug shows a distinctly
different color, the engine could be defec-
tive. Do not attempt to diagnose any prob-
lems yourself. Have a Yamaha dealer
service the watercraft.
Remove and inspect the spark plugs peri-
odically; heat and deposits will cause the
spark plugs to slowly break down and erode.
If electrode erosion becomes excessive, or if
carbon and other deposits are excessive,
replace the spark plug with the specified
plug.
Removing a spark plug:
1. Remove the air filter case cover and air
filter element. (See page 4-14 for air filter
removal and installation procedures.)
2. Remove the spark plug cap.
CAUTION:@ Do not use any tools to remove or install
the spark plug cap, otherwise the igni-
tion coil coupler may get damaged. The
spark plug cap may be difficult to remove
because the rubber seal on the end of
the cap fits tightly. To remove the spark
plug cap, simply twist it back and forth
while pulling it up; to install it, twist it
back and forth while pushing it down.
@
3. Remove the spark plug.
Specified spark plug: NGK CR9EB
