Watercraft operation
29
TIP
If the RiDE lever is squeezed while the throttle
lever is squeezed, the watercraft will slow
down, and once stopped, move in reverse.
To shift into neutral from forward:
(1) Release the throttle lever.
(2) Lightly squeeze and release the RiDE le-ver. The “N” (neutral) shift indicator will
be displayed.
TIP
If the RiDE lever is squeezed continuously,
the reverse gate will move to the reverse po-
sition.
EJU47170Electric trim system
The electric trim system is a function for
changing the vertical angle of the jet thrust
nozzle to change the trim angle and perfor-
mance characteristics of the watercraft.
This function can be used only for forward
operation of the watercraft.
TIP
When the watercraft is moving in reverse or
is in neutral, the jet thrust nozzle will auto-
matically change to the neutral trim setting.
When the watercraft is shifted into forward,
the jet thrust nozzle will automatically
change to the selected trim setting.
The watercraft perfor mance characteristics
according to the trim angle change de-
pending on the operating conditions.
Confirming the trim setting
The trim setting can be confirmed by the trim
setting indicator on the multifunction infor-
mation center.

Watercraft operation
30
To change the trim setting:
(1) Shift into forward.
(2) Push the upper side of the “TRIM” switchto increase the trim setting and raise the
bow, or push the lower side of the
“TRIM” switch to de crease the trim set-
ting and lower the bow. The trim angle
can be adjusted in the range of the trim
settings –1 to +3.
Bow-up positions
The bow will go up, causing the trim angle to
increase.
There is less water resistance, therefore,
straight-ahead acceleration is enhanced. Bow-down positions
The bow will go down, causing the trim angle
to decrease.
Vertical movement of the bow will be reduced
and the watercraft will get up on plane more
quickly when accelerating.

Multifunction information center
The multifunction information center displays
various watercraft information.
Multifunction information center initial op-
eration
When the multifunction information center is
activated, all of the display segments come
on. After 2 seconds, the warning indicators in
the information display go off, and then the
center starts to operate normally.
TIP
The multifunction information center is turned
on, even if the engine start/stop switch is also
pushed briefly.
Multifunction information center standby
state
If the multifunction information center does
not receive any operation input within 30 sec-
onds after the engine stops, the center will
turn off and enter a standby state. When the
engine is started again, the displays return to
their state before the center turned off, and
then the center starts to operate normally.
EJU35028Information display
The information display shows watercraft op-
erating conditions.
EJU47131Speedometer
The speedometer shows the watercraft
speed.
By switching the display units, the speed can
be shown in kilometers per hour “km/h” or
miles per hour “MPH”.
TIP
“MPH” is selected as the display unit at the
Yamaha factory.

The tachometer shows the engine speed.
TIP
While the engine is stopped, the battery volt-
age and the total engine hours are displayed
alternately.
EJU43891Shift indicator
This indicator shows the reverse gate shift
positions: “F” (forward), “N” (neutral), and “R”
(reverse). (See page 27 for shifting proce-
dures.)
EJU47181Trim indicator
This indicator shows the trim angle of the jet
thrust nozzle. When the neutral position of
the jet thrust nozzle is selected, the trim indi-
cator shows the segment next to the trim
icon. Increasing the trim angle will show the

creasing the trim angle will show the lower
segment of the trim indicator. (See page 29
for trim angle selection procedures.)
EJU44701Hour meter and voltmeter
The hour meter and voltmeter are displayed
in the tachometer portion of the information
display while the engine is stopped.
The hour meter and voltmeter are displayed
alternately at 3-second intervals.
TIP
If the engine is stopped after the check en-
gine warning is activated, the hour meter and
error code will be displayed alternately at 3-
second intervals.
Hour meter
The hour meter shows the total number of
hours that the engine has been running since
the watercraft was new.
TIP
The elapsed time will be kept even if the bat-
tery terminals have been disconnected.
Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage has dropped significant-
ly, “Lo” is displayed on the voltmeter, and all
other display segments of the information
display turn off. If the battery voltage has ris-
en significantly, “HI” is displayed. If “Lo” or
“HI” is displayed, immediately return to shore
and have a Yamaha dealer service the water-
craft.

them, and then make sure that the plugs and
O-rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs.
NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads and the O-
rings on the plugs to remove any foreign
materials, such as dirt or sand. Otherwise,
