Safe boating rules
Your Yamaha watercraft is legally consid-
ered a powerboat. Operation of the water-
craft must be in accordance with the rules
and regulations governing the waterway on
which it is used.
EJU10061
Enjoy your watercraft
responsibly
You share the areas you enjoy when riding
your watercraft with others and with nature.
So your enjoyment includes a responsibility
to treat these other people, and the lands,
waters, and wildlife with respect and cour-
tesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the exciting
splash of your wake can make waves others
won’t enjoy. Avoid riding close to shoreline
homes and waterfowl nesting areas or other
wildlife areas, and keep a respectful distance
from fishermen, other boats, swimmers, and
populated beaches. When travel in areas like
these is unavoidable, ride slowly and obey all
laws.
Proper maintenance is necessary to
ensure that the exhaust emission and sound
levels of your watercraft will continue to be
within regulated limits. You have the responsi-
bility to make sure that the recommended
maintenance in this Owner’s/Operator’s Man-
ual is carried out.
Remember that pollution can be harmful to
the environment. Do not refuel or add oil
where a spill could cause damage to nature.
Remove your watercraft from the water and
move it away from the shoreline before refuel-
ing. And keep your surroundings pleasant for
the people and wildlife that share the water-
ways: don’t litter!
When you ride responsibly, with respect
and courtesy for others, you help ensure that
our waterways stay open for the enjoyment of
a variety of recreational oppor tunities.

Oil pressure warning indicator
If the oil pressure does not rise to specifi-
cation, the “WARNING” indicator light and
the oil pressure warning indicator begin to
blink and the buzzer sounds intermittently.
At the same time, the engine speed is lim-
ited to help prevent damage.
If this occurs, reduce the engine speed,
return to shore, and then check the engine
oil level. (See page 3-7 for engine oil level
checking procedures.) If the oil level is low,
add enough engine oil to raise it to the
proper level. If the oil level is sufficient, have
a Yamaha dealer check the watercraft.
NOTE:@ Press any button on the multifunction meter
to stop the buzzer.

Fuel and oil
This watercraft is equipped with a
4-stroke engine. Conventional 2-stroke
engine oil cannot be used.
The engine utilizes an electronic fuel
injection system to deliver the optimal air-
fuel mixture ratio required by the engine.
With optimal combustion conditions, this
system is able to increase startability and
improve fuel economy.
EJU19112
Gasoline
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!
Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.
Stop engine before refueling.
Refuel in a well-ventilated area with
the watercraft in a horizontal position.
Do not stand or sit on the watercraft
while refueling in case of fire.
Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.
Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approx-
imately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do
not leave it in direct sunlight. Leave it
in a well-ventilated area with the water-
craft in a horizontal position.

Pre-operation checks
EJU01347
Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the
accompanying text in this chapter for details on how to perform the checks.
WARNING@ If any item in the pre-operation check list is not working properly, have it inspected
and repaired before operating the watercraft, otherwise an accident could occur.
@
NOTE:@ Pre-operation checks should be made thoroughly each time the watercraft is used. This pro-
cedure can be completed in a short time. It is worth the time spent to assure safety and reli-
ability.

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.)

4. Remove the oil tank filler cap 1, wipe
the dipstick clean, and then screw the
filler cap into the filler hole completely.
Remove the filler cap again and check
that the oil level is between the minimum
level mark 3 and maximum level
mark2 on the dipstick.
5. If the oil level is below the minimum level
mark, add enough oil so that the oil level
is between the minimum and maximum
level marks on the dipstick, and then
install the filler cap. If the engine oil level
is significantly above the maximum level
mark, the oil tank is overfilled. Have a
Yamaha dealer remove the excessive
amount of engine oil.

Water separator
Check the water separator 1 for water.
Normally the water separator is empty. The
water separator retains any water entering
through the fuel tank breather hose if the
watercraft is capsized.
If water remains in the water separator,
drain it by removing the drain screw 2.
Place a drain pan under the water separator
to catch the draining water or use a dry cloth
to soak up any water that could spill into the
watercraft. If any water spills into the water-
craft, be sure to wipe it up with a dry cloth.
Be sure to install the drain screw after drain-
ing the water separator.

Operation
WARNING@ Before operating your watercraft,
become familiar with all controls. Con-
sult your Yamaha dealer about any con-
trol or function you do not fully
understand. Failure to understand how
controls work could cause an accident or
prevent you from avoiding an accident.
CAUTION:@ Make sure that the stern drain plugs are
securely tightened before launching the
watercraft.
EJU18072
Engine break-in
The engine break-in period is essential to
allow the various components of the engine
to wear and polish themselves to the correct
operating clearances. This ensures proper
performance and promotes longer compo-
nent life.
CAUTION:@ Be sure to check the engine oil level
before operating the watercraft for the
first time. (See page 3-7 for engine oil
checking procedures.)
@
1. Launch the watercraft and start the
engine. (See page 3-19 for engine start-
ing procedures.)

Inspecting the battery
Check the level of the battery electrolyte
and make sure that the negative and posi-
tive leads are securely tightened.
WARNING@ Battery electrolyte is poisonous and
dangerous, causing severe burns, etc.
Electrolyte contains sulfuric acid.
Avoid contact with skin, eyes, or cloth-
ing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Call phy-
sician immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries produce explosive gases.
Keep sparks, flame, cigarettes, etc.,
well away. If using or charging the bat-
tery in an enclosed space, make sure
that it is well ventilated. Always shield
your eyes when working near batter-
ies.
KEEP OUT OF THE REACH OF CHIL-
DREN.
Be sure to connect the breather hose
to the battery. Fire or explosion could
result if the breather hose is damaged,
obstructed, or not connected properly.
@
CAUTION:@ Be careful not to place the battery on
its side.
Be sure to remove the battery from the
battery compartment when adding
electrolyte or charging the battery.
