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.

Boarding with a passenger
WARNING@ Severe internal injuries can occur if
water is forced into body cavities as a
result of being near the jet thrust nozzle.
Do not apply throttle until the passenger
is seated with his or her feet on the floor
of the footwell and is holding on to the
operator.
@
1. Climb on board as noted in the previous
section, and sit astride the seat. Attach
the engine shut-off cord to your wrist,
and then install the clip to the engine
shut-off switch.
2. Have the passenger move to the rear of
the watercraft.
3. Have the passenger get on board and sit
on the seat.
NOTE:@ When a passenger is getting on board, both
the passenger and the operator should try to
balance the watercraft.
@
4. The operator should check to see that
the passenger has his or her feet on the
floor of the footwell and that he or she is
securely holding on to the operator.
5. Start the engine, look in all directions,
and then accelerate to planing speed.
WARNING@ Before starting off, make sure that there
are no boats, obstructions, or swimmers
around you.

Post-operation checks
WARNING@ Stay away from stern when engine is run-
ning on land. Hot water and steam spurt-
ing from exhaust outlet into the air can
cause serious burns.
@
Always perform the following post-opera-
tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, handlebars, and jet
unit with fresh water.
3. Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow water in the bilge to
drain out.
NOTE:@ This watercraft is equipped with a jet vac-
uum bilge draining system and an electric
bilge draining system that remove water
from the engine compartment while you are
underway. However, some residual water will
remain. (See “Bilge” on page 3-9 for more
information.)
@
4. Put the watercraft in a horizontal posi-
tion.
5. Flush the cooling system to prevent it
from clogging with salt, sand, or dirt.
(See page 4-1 for flushing procedures.)
6. Drain residual water from the exhaust sys-
tem by running the engine at 4,000 r/min
for 10 to 15 seconds.
CAUTION:@ Do not run engine over 4,000 r/min on
land. Otherwise catalytic converter could
sustain serious damage.

NOTE:@ The condition of the battery can be known
by checking the specific gravity of the elec-
trolyte. However, you can also know the con-
dition of the battery by measuring the
voltage at both battery terminals. Charge
the battery if the voltage is less than
12 volts.
It is recommended to have a Yamaha dealer
check the specific gravity and to charge the
battery. If you maintain the battery yourself,
be sure to read and follow the instructions
provided with the battery tester and charger
you use.

Cleaning the watercraft
Clean the watercraft before storing it for a
long period.
WARNING@ Do not spray flammable rust inhibitor
products on engine surfaces while the
engine is hot. The sprayed substance or
propellants could catch fire.
@
1. Wash down the hull, handlebars, and
drive unit with fresh water.
2. Rinse the engine and bilge area with
fresh water. Drain off all water and wipe
up remaining moisture with clean, dry
rags.
3. Spray the engine’s exterior with a rust
inhibitor or lubricant.
4. Wax the hull with a non-abrasive wax.
5. Wipe all vinyl and rubber components,
such as the seat and engine compart-
ment seals, with a vinyl protectant. Specific gravity (for reference):
1.28 at 20 °C (68 °F)

Inspecting the fuel system
WARNING@ Gasoline is highly flammable and explo-
sive. Failure to check for and repair any
fuel leakage could result in fire or explo-
sion. A fire or explosion can cause
severe injury or death. Shut off the
engine. Do not smoke. Avoid spilling
gasoline.
Fuel in hose is pressurized.
Fuel can spray out and cause injury or a
fire hazard if fuel line is disconnected.
Do not attempt to run engine with fuel
line disconnected.
@
Check the fuel system for leaks, cracks,
or malfunctions. If any problem is found,
consult a Yamaha dealer.
Check:
Fuel tank for water or dirt.
Fuel tank cap (seal) for damage.
Fuel tank for damage, cracks or leakage.
Fuel hose joint for leakage.
Fuel hose for cracks or other damage.
Air bleeding passages for leakage.
EJU18410
Fuel tank
Check the fuel tank 1 for leakage or
water in the tank. If water is found in the fuel
system or if the fuel tank needs to be
cleaned, have a Yamaha dealer service the
watercraft.

Adjusting the fuel injection
system
The fuel injection system was set at the
Yamaha factory. Have a Yamaha dealer ser-
vice the watercraft if necessary.
CAUTION:@ Do not attempt to adjust the fuel injection
system. If the settings are changed poor
engine performance and damage may
result.

EJU20240
Checking the trolling speed
1. Put the watercraft in the water.
2. Start the engine and warm it up. Use the
tachometer in the multifunction informa-
tion center to check the trolling speed.
If the trolling speed is out of specification,
have a Yamaha dealer service the water-
craft. Trolling speed: 1,250–1,450 r/min

Emergency procedures

Cleaning the jet intake and
impeller
If weeds or debris get caught in the intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine
speed rises. If this condition is allowed to
continue, the engine will overheat and may
seize. If there is any sign that the jet intake
or impeller is clogged with weeds or debris,
beach the watercraft and check the intake
and impeller. Always stop the engine before
beaching the watercraft.
WARNING@ Before attempting to remove weeds or
debris from the jet intake or impeller
areas, shut the engine off and remove
the clip from the engine shut-off switch.
Severe injury or death could result from
contact with the rotating parts of the jet
pump.
@
1. Turn the watercraft on its side as shown.
CAUTION:@ Place a suitable clean cloth or carpet-
ing underneath the watercraft to pro-
tect it from abrasions and scratches.
Always turn the watercraft over onto
its port (left) side.
When turning the watercraft on its
side, support the bow so the handle-
bars cannot be bent or damaged.
