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 28 for shifting proce-
dures.)
EJU44700Hour meter and voltmeter

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.
EJU37272Fuel level meter
The fuel level meter shows the amount of fuel
remaining in the fuel tank. The amount of re-
maining fuel is shown using four display seg-
ments, which disappear one at a time as the
fuel level decreases.
TIP:
The accuracy of the fuel level meter varies
depending on the operating conditions. Use
this function as a reference only.

nozzle moves as the handlebars are turned,
and that there is no difference between the right and left fully turned positions of the jet
thrust nozzle.
