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.

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:@
For the first tankful of operation, pre-
mix a 50:1 mixture of fuel and oil (in
addition to the oil in the oil tank).

After break-in, use straight gasoline
for normal operation.

Starting the engine
WARNING@ Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monox-
ide, a colorless, odorless gas that may
cause loss of consciousness and death
within a short time. Always operate the
watercraft in an open area.
@
1. Launch the watercraft in water free from
weeds and debris and at least 60 cm
(2 ft) deep.
WARNING@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise you increase
your chance of hitting a submerged
object, which could result in injury.
@
CAUTION:@ Never operate in water that is less than
60 cm (2 ft) deep, otherwise pebbles or
sand could be sucked into the jet intake,
causing impeller damage or engine over-
heating.

2. Attach the clip 1 to the engine shut-off
switch 2. Also, attach the engine shut-
off cord 3 to your left wrist.
WARNING@ Check that the engine shut-off cord is not
frayed or broken, and keep it free from
the handlebars so the engine stops if the
operator falls off. The engine shut-off
cord may not pull free if wrapped around
the handlebars when the operator falls
off, allowing the watercraft to continue to
run and cause an accident.
@
NOTE:@ It is not possible to start the engine with the
clip removed from the engine shut-off
switch.
@
3. Push the start switch (green button).
NOTE:@ The engine will not start if the throttle lever is
squeezed.
@
4. Release the start switch as soon as the
engine starts to run.
CAUTION:@
Never push the start switch while the
engine is running.

Do not operate the start switch for
more than 5 seconds, otherwise the
battery will be discharged and the
engine will not start. Also, the starter
motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
then try again.

Operating your watercraft
EJU10690
Getting to know your
watercraft
Operating your watercraft requires skills
acquired through practice over a period of
time. Take the time to learn the basic tech-
niques well before attempting more difficult
maneuvers.
Operating your new watercraft can be a
very enjoyable activity, providing you with
hours of pleasure. However, it is essential to
familiarize yourself with the operation of the
watercraft to achieve the skill level neces-
sary to enjoy riding safely. Before operating
this watercraft, read this Owner’s/Operator’s
Manual, the Riding Practice Guide, and all
warning and caution labels on the water-
craft. Pay particular attention to the safety
information on pages 1-9 to 1-15. These
materials should give you an understanding
of the watercraft and its operation.
Remember: This watercraft is designed to
carry the operator and one passenger.
Never exceed the maximum load limit or
allow more than 2 persons to ride the water-
craft at one time.
EJU10700
Learning to operate your
watercraft
Before operating the watercraft, always
perform the pre-operation checks listed on
page 3-6. The short time spent checking the
watercraft will reward you with added safety
and reliability.
Check all local laws before operating your
watercraft.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft. Select a wide
area to learn in, where you have good visi-
bility and light boat traffic.
Use the buddy system—operate with
someone nearby. Scan constantly for peo-
ple, objects, and other watercraft. Be alert
for conditions that limit your visibility or block
your vision of others.
Attach the engine shut-off cord (lanyard)
to your wrist and keep it free from the han-
dlebars so that the engine stops if the opera-
tor falls off.
Wear a personal flotation device (PFD).
All riders must wear an authority-approved
PFD that is suitable for personal watercraft
use. Maximum load: 160 kg (353 lb)
Load is the total weight of cargo,
operator and passenger.

Wear protective clothing. Severe internal
injuries can occur if water is forced into body
cavities as result of falling into the water or
being near the jet thrust nozzle. Normal
swimwear does not adequately protect
against forceful water entry into rectum and
vagina. All riders must wear a wetsuit bot-
tom or clothing that provides equivalent pro-
tection.
Such clothing includes thick, tightly
woven, sturdy and snug-fitting apparel such
as denim, but does not include spandex or
similar fabrics like those used in bicycle
shorts. A full wetsuit can also protect against
hypothermia (subnormal body temperature)
and abrasions.
Footwear and gloves are recommended.
Eye protection is recommended to keep
wind, water, and glare from the sun out of
your eyes while you operate your watercraft.
Restraining straps for eyewear are made
which are designed to float should your eye-
wear fall in the water.
You should grip the handlebars firmly and
keep both feet on the floor of the footwell. Do
not attempt to ride with passengers until
your operating skills are fully developed. EJU10710
Riding watercraft with a
passenger
When a passenger is on board with the
operator, the watercraft handles differently,
and is not as easy to maneuver, so operat-
ing it requires a higher degree of skill.
Before attempting to operate the watercraft
with a passenger on board, the operator
must practice operating the watercraft alone
enough to be able to acquire the necessary
skills.
The passenger must always wear an
authority-approved PFD and a wetsuit bot-
tom or equivalent.
WARNING@ Do not apply throttle when anyone is at
rear of watercraft. Turn engine off or keep
engine at idle. Water and/or debris exit-
ing the jet thrust nozzle can cause severe
injury. The passenger should not attempt
to board the watercraft if the operator is
applying throttle.
@
Do not give a ride to a child whose feet
cannot reach the floor of the footwell. The
passenger should hold on firmly to the oper-
ator and keep both feet in the footwell.
WARNING@ When a passenger is on board, make
sure that he or she is holding on firmly
and has his or her feet in the footwell
before you start to accelerate.

Starting the watercraft
WARNING@
Scan constantly for people, objects,
and other watercraft. Be alert for con-
ditions that limit your visibility or block
your vision of others.

Operate defensively at safe speeds
and keep a safe distance away from
people, objects, and other watercraft.

Do not follow directly behind water-
craft or other boats. Do not go near
others to spray or splash them with
water. Avoid sharp turns or other
maneuvers that make it hard for others
to avoid you or understand where you
are going. Avoid areas with sub-
merged objects or shallow water.

Take early action to avoid collisions.
Remember watercraft and other boats
do not have brakes. Do not release the
throttle when trying to steer away from
objects—you need throttle to steer.

Practice reboarding in shallow water
before riding in deep water.

Boarding and starting in deep
water
WARNING@
Operator and passenger should prac-
tice getting on board in shallow water
before riding in deep water. Boarding
in deep water requires more skill.

The fatigue and exposure that could
result after unsuccessful attempts to
get back on the watercraft may
increase the risk of injuries and drown-
ing.
@
EJU18380
Boarding alone
1. Swim to the rear of the watercraft and
place both hands on the boarding plat-
form, pull yourself up, and then grasp the
handgrip with one hand.
2. Pull yourself up to a kneeling position on
the platform, and then move to the seat
and sit astride.
3. Attach the engine shut-off cord to your
left wrist, and then install the clip to the
engine shut-off switch.
4. Grip the handlebars firmly with both
hands, place both feet on the floor of the
footwell, start the engine, and then look
in all directions before starting off.
WARNING@ Before starting off, make sure that there
are no boats, obstructions, or swimmers
around you.
