Hour meter/Voltmeter
NOTE:@ To switch the display between the hour
meter and voltmeter, push the select
button1 for at least 1 second after the
meter is displayed for more than 10 sec-

@
Hour meter
The hour meter is provided to make it
easy to follow the maintenance schedule.
The meter shows the hours of engine
operation that have elapsed since the water-
craft was new.
Vo l t m e t e r
The voltmeter is provided to display the
voltage of the battery.
The voltmeter displays 12 volts or more
when the battery voltage is within specifica-
tion.
If the voltage displayed is low, beach the
watercraft and, if necessary, have a Yamaha
dealer check the charging system.

Fuel warning indicator
If the fuel remaining in the tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the
lowest two fuel level segments, the fuel
warning indicator and the warning light
begin to blink. The buzzer also starts sound-
ing intermittently.
The warning signals will be cleared when
the engine restarts after refilling fuel.

Battery
Check the battery condition and the elec-
trolyte level.
Check that the battery leads are tightened
securely and there is no corrosion on the
battery terminals.
WARNING@
The battery must always be fully
charged and in good condition. Loss
of battery power may leave you
stranded. Never operate the watercraft
if the battery does not have sufficient
power to start the engine or if it shows
any other signs of decreased power.

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.
@
Make sure that the battery is securely
held in place.

Fire extinguisher
Check that there is a full fire extinguisher
on board. The fire extinguisher container 1
is located in the battery compartment.
To open the fire extinguisher container
cap 2 remove the seat and turn it counter-
clockwise.
After inserting the fire extinguisher make
sure that the container cap is tightened
securely.
NOTE:@
See the instructions supplied by the fire
extinguisher manufacturer for checking
the fire extinguisher. Always keep the
extinguisher in the fire extinguisher con-
tainer.

Always carry a fire extinguisher on board.
A fire extinguisher is not standard equip-
ment with this watercraft. If you do not
have one, contact a Yamaha dealer or a
fire extinguisher dealer to obtain one
meeting the proper specifications.

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.

Battery
If the watercraft will not be used for more
than a month, disconnect the negative (–)
lead first, then the positive (+) lead and
breather hose, and then remove the battery
from the watercraft.
Clean the battery casing using fresh
water.
If the battery terminals are dirty or cor-
roded, clean them with a wire brush.
Fully charge the battery, and then store it
in a cool, dark place.
Apply Yamaha marine grease or Yamaha
grease A to the battery terminals.
Check the battery at least every 2 months
and fully charge it if necessary.
WARNING@ 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:@ The battery may not be usable again if
you store it for a long period without
charging it. Charge the battery periodi-
cally.

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.

EJU18800
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)
