Instrument operation
35
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.
To switch to the voltmeter from the hour
meter:
Push the select button for at least 1 second af-
ter the multifunction information center is acti-
vated for more than 10 seconds. The display
switches to the voltmeter from the hour meter.
EJU31514Fuel 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 eight display seg-
ments, which disappear two at a time as the
fuel level decreases.
TIP:
The accuracy of the fuel level meter varies de-
pending on the operating conditions. Use this
function as a reference only.
EJU41970Fuel level warning
If the fuel remaining in the fuel tank drops to
about 17 L (4.5 US gal, 3.7 Imp. gal), the low-
est two fuel level segments, the fuel level
warning indicator, and the “WARNING” indi-
cator light blink, and the buzzer sounds inter-
mittently.
If the fuel level warning is activated, refill the
fuel tank as soon as possible. (See page 44
for information on filling the fuel tank.)
After the fuel tank is refilled, the warning sig-
nals will be cleared when the engine is restart-
ed.

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 71 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 72 for in-formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU40633Lubrication
Use a suitable marine grease applicator and
spray a rust inhibitor between the inner and
outer cables to lubricate the cables and purge
out any dirt and moisture.
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)
●Shift cable (shift lever end)Recommended water-resistant grease:

(7) Securely install the seat in its original po-sition.
If the fuse immediately blows again, the elec-
trical system may be defective. If this occurs,
have a Yamaha dealer service the watercraft.
EJU34715Towing the watercraft
WARNING
EWJ00811
●The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the operator on the watercraft.
●The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.
To tow the watercraft:
Use a towline that is three times the combined
length of the towing boat and the watercraft.
(1) Securely attach the towline to the bow eye of the watercraft being towed.
(2) Sit astride the seat and hold on to the handlebars in order to balance the water-
craft. NOTICE: The bow must be kept
up out of the water during towing, oth-
erwise water could flood the engine
compartment or water could flow back into the engine, causing severe en-
gine damage.
[ECJ01330]
Tow the watercraft at 8 km/h (5 mph) or less.
NOTICE: Tow the watercraft at 8 km/h (5
mph) or less, otherwise water could flood
the engine compartment or water could
flow back into the engine, causing severe
engine damage.
[ECJ01321]
EJU36155
Submerged watercraft
If the watercraft is submerged or flooded with
water, drain the bilge water from the engine
compartment. Then, have a Yamaha dealer
service the watercraft as soon as possible.
If the watercraft was submerged:
(1) Remove the watercraft from the water and drain the water from the storage
compartments. (See page 40 for informa-
tion on draining the storage compart-
ments.)
(2) Drain the bilge water from the engine compartment. (See page 47 for informa-
tion on draining the bilge water.)
(3) Have the watercraft serviced by a Yamaha dealer as soon as possible.
NOTICE: Be sure to have a Yamaha
dealer inspect the watercraft. Other-
wise, serious engine damage could re-
sult.
