EJU35024Information display
The information display shows watercraft op-
erating conditions.
EJU37264Hour meter/voltmeter
The hour meter/voltmeter has both an hour
meter function and a voltmeter function. By
switching the meter, it can be used as either
an hour meter or a voltmeter.
TIP:
The hour meter is selected at the Yamaha
factory.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.
To switch to the hour meter from the voltme-
ter:
Push the “Hour Volt” button for at least 1 sec-
ond. The display switches to the hour meter
from the voltmeter.
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. If the
battery voltage has risen significantly, “HI” is
displayed. If “LO” or “HI” is displayed, immedi-
ately return to shore and have a Yamaha
dealer service the watercraft.

EJU33492
Long-term storage
WARNING
EWJ00330
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create a
fire hazard.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage.
However, the following procedures can be
performed easily by the owner.
EJU40762Cleaning
(1) Flush the cooling water passages. (Seepage 78 for information on flushing the
cooling water passages.)
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(2) Clean the watercraft. (See page 79 for in-formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU41260Lubrication
Use a suitable marine grease applicator to
pressure-lubricate the cables and purge out
any moisture between the inner and outer ca-
bles.
To keep moving parts sliding or rotating
smoothly, lubricate them with water-resistant
grease.
●Throttle cable (throttle lever end)
●Steering cable (jet thrust nozzle end) and
Q.S.T.S. rod (jet thrust nozzle end)
●Shift cable (reverse gate end)
EJU40811Rustproofing
Spray metallic parts of the hull, deck, and en-
gine with a rust inhibitor.Recommended water-resistant grease:
