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. (See
page 72 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 73 for in-
formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU40634Lubrication
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.

EJU41671Rustproofing
Rustproofing the hull, deck, and engine
Spray metallic parts of the hull, deck, and en-
gine with a rust inhibitor.
Rustproofing the internal engine compo-
nents
Rustproof the internal engine components
with a rust inhibitor.
To rustproof the internal engine components:
(1) Remove the seat. (See page 38 for seat
removal and installation procedures.)
(2) Loosen the clamp screw and disconnect
the air intake duct.
(3) Spray a rust inhibitor into the intake
opening for 3 seconds. WARNING! Do
not spray flammable rust inhibitor
products on engine surfaces while theengine is hot. The sprayed substance
or propellants could catch fire.
[EWJ00262]
(4) Connect the air intake duct and securely
tighten the clamp screw.
(5) Make sure that the area around the wa-
tercraft is clear, and then start the engine
in a well-ventilated area and let it run at
idle for 15 seconds. (See page 27 for in-
formation on starting the engine.)
(6) Stop the engine.
(7) Securely install the seat in its original po-
sition.

Maintenance

EJU33769
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.
WARNING
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.
