Post-operation careEWJ00332
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.
After using the watercraft, always take it out
of the water, clean it, and store it. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deteriora-
tion of the jet pump and hull. Marine organ-
isms and corrosion are some of the
conditions that can shorten the life of many
watercraft components.
EJU46120Flushing the cooling water passagesECJ01880
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for
more than 15 seconds without supplying
water, otherwise the engine could over-
heat.
Flush the cooling water passages to
prevent them from clogging with salt,
sand, or dirt.
(1) Place the watercraft in a horizontal posi-tion.
(2) Remove the seats and seat storage compartment. (See page 48 for seat re-
moval and installation procedures and
page 52 for information on the seat stor-
age compartment.)
(3) Connect the garden hose adapter to a garden hose. (4) Loosen the flushing hose connector cap
and remove it. Insert the garden hose
adapter into the flushing hose connector
by pushing and twisting it until it is se-
curely connected.
(5) Connect the garden hose to a water tap.
(6) Make sure that the area around the wa- tercraft is clear, and then start the en-
gine. Immediately after the engine starts,
fully turn the water supply on so that wa-
ter flows out continually from the jet
thrust nozzle.

gine compartment as severe engine
damage could result.
[ECJ00572]
(3) Drain the water from the engine com-
partment. (See page 59 for information
on draining the bilge water.)
(4) Wipe the engine and engine compart- ment with a dry cloth.
(5) Wash down the hull, deck, and jet pump with fresh water.
(6) Wipe the hull, deck, and jet pump with a dry cloth.
(7) Wipe all vinyl and rubber components, such as the seats and engine compart-
ment seals, with a vinyl protectant.
(8) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.
(9) Allow the engine compartment to air dry completely before installing the seats.
(10) Securely install the seats in their original positions.
EJU3368DBattery care
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.
EWJ00794

gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
Keep out of the reach of children.

(3) Unhook the battery bands, and then re-move the battery from the watercraft.
Checking the battery
Make sure that the battery case is not dam-
aged.
Make sure that the battery terminals are
not corroded or damaged.
Checking the battery voltage and charging
the battery
It is recommended to have a Yamaha dealer
check the battery voltage and charge the bat-
tery. Have a Yamaha dealer charge the bat-
tery as soon as possible if it seems to have
discharged. Keep in mind that the battery
tends to discharge more quickly if the vehicle
is equipped with optional electrical accesso-
ries. NOTICE: To charge a VRLA (Valve Regulated Lead Acid) battery, a special
(constant-voltage) battery charger is re-
quired. Using a conventional battery char-
ger will damage the battery.
[ECJ02810]
Checking the battery bands
Make sure that the battery bands are not
damaged.
To store the battery:
(1) Clean the battery case using fresh water.
(2) If the battery terminals are dirty or cor-
roded, clean them using a wire brush.
(3) Apply water-resistant grease to the bat- tery terminals.

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 83 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 84 for in-formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.

Maintenance
Periodic checks and lubrication will keep
your watercraft in the safest and most effi-
cient condition possible. Therefore, make
sure to carry out the periodic maintenance.
Safety is an obligation of the watercraft own-
er. Proper maintenance must be carried out
to keep the exhaust emission and sound lev-
els within the regulated limits. The most im-
portant points of watercraft inspection and
lubrication are explained on the following
pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories
designed for your watercraft.
Remember, failures that are the result of the
installation of parts or accessories which are
not qualitatively equivalent to genuine
Yamaha parts are not covered by the limited warranty.
Maintenance, replacement, or repair of
the emission control devices and system
may be performed by any marine SI engine
repair establishment or individual. War-
ranty repair, however, must be performed
at an authorized Yamaha marine dealer-
ship.
EWJ00312
Be sure to turn off the engine when you
perform maintenance unless otherwise
specified. If you are not familiar with ma-
chine servicing, this work should be done
by a Yamaha dealer or other qualified me-
chanic.
