Bow down
Turn the grip to A or B and the bow will
go down while the watercraft is on plane.
Bow down puts more of the bow in the
water. This gives the watercraft more “hook,”
which enhances turning performance. This
position will also help the watercraft get up
on plane more quickly.
At higher speeds, however, the watercraft
will have greater tendency to “bow steer”
and follow waves and wakes in the water.
Fuel economy and maximum speed are also
reduced.
EJU01024
Bow up
Turn the grip to C or D and the bow will
go up while the watercraft is on plane.
Bow up puts less of the bow in the water.
There is less water resistance, so straight-
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the water-
craft may tend to “porpoise” (hop in the
water). If the watercraft is porpoising,
choose neutral or bow down.
EJU01967
Handgrip
The handgrip 1 provides a handhold for
boarding the watercraft and for a spotter
when facing rearward.
WARNING@ Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.

The engine speed (r/min) is displayed by
segments. Each segment indicates a 250 r/min
increment.

Hour meter/Voltmeter
NOTE:@ To switch the display between the hour
meter and voltmeter, push the hour meter/
voltmeter display select switch 1 for at least
2 seconds.
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.
EJU01791
Check engine warning indicator
If a sensor malfunction or a short circuit is
detected, the warning indicator begins to
blink and the buzzer sounds intermittently.
If this occurs, reduce the engine speed,
beach the watercraft, and have a Yamaha
dealer check the engine.

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 fuel level segment and the fuel warn-
ing indicator begin to blink, and the buzzer
sounds intermittently.
If this occurs, fill the fuel tank at the first
opportunity.
EJU01793
Oil pressure warning indicator
If the oil pressure does not rise to specifi-
cation, the oil pressure warning indicator
come on and the buzzer begins to sound
continuously. At the same time, the engine
speed reduction control is activated.
If this occurs, reduce the engine speed,
beach the watercraft, and have a Yamaha
dealer check the oil pressure.
NOTE:@ Press any button on the multifunction meter
to stop the buzzer.

EJU01794
Engine overheat warning indicator
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the over-
heat warning indicator blinks for 5 seconds,
and then it comes on. The buzzer also
begins to sound intermittently, and then it
sounds continuously. At the same time, the
engine speed reduction control is activated
when the engine runs over 3,000 r/min.
If this occurs, immediately reduce the
engine speed and beach the watercraft, and
check for water discharge at the port (left)
cooling water pilot outlet. If there is no dis-
charge of water, check the intake grate and
impeller for clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
CAUTION:@ If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe
engine damage.
NOTE:@ Press any button on the multifunction meter
to stop the buzzer.
