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

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, imme-
diately return to shore and have a Yamaha
dealer service the watercraft.

EJU33493
Long-term storage
WARNING
EWJ00331
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.
EJU40763Cleaning
(1) Flush the cooling water passages. (Seepage 79 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 80 for in-formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU41261Lubrication
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)
EJU40812Rustproofing
Spray metallic parts of the hull, deck, and en-
gine with a rust inhibitor.Recommended water-resistant grease:

If the fuse immediately blows again, the elec-
trical system may be defective. If this occurs,
have a Yamaha dealer service the watercraft.
EJU34716Towing the watercraft
WARNING
EWJ00812
The operator of the towing boat must
keep speed to a minimum and avoid
traffic or obstacles which could be a
hazard to the operator on the water-
craft.
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 com-
bined length of the towing boat and the wa-
tercraft.
(1) Securely attach the towline to the boweye 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
engine damage.
[ECJ01331]
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.
[ECJ01322]
EJU36156
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 44 for infor-
mation on draining the storage compart-
ments.)
(2) Drain the bilge water from the engine compartment. (See page 52 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
result.
