Maintenance and care
47
To check the condition of the battery, check
the specific gravity of the electrolyte or mea-
sure the voltage at both battery terminals.
Charge the battery if the voltage is less than
12 volts.
It is recommended to have a Yamaha dealer
check the specific gravity and charge the bat-
tery. If you maintain the battery yourself, be
sure to read and follow the instructions provid-
ed with the battery tester and charger you
use.
EJU33701Cleaning the watercraft
Clean the watercraft before storing it for a long
period.
(1) Wash down the hull, handlebars, and jet
unit with fresh water.
(2) Rinse the engine and engine compart-
ment with fresh water. Drain all of the wa-
ter and wipe up any remaining moisture
with clean, dry rags. NOTICE: Do not
use high-pressure water when rinsing
the engine and engine compartment
as severe engine damage could result.
[ECJ00111]
(3) Spray the engine’s exterior with a rust in-
hibitor and lubricant.
(4) Wax the hull with a non-abrasive wax.
(5) Wipe all vinyl and rubber components,
such as the engine compartment seals,
with a vinyl protectant. Do not use vinyl
protectant on the riding tray, because it
will make it slippery.

Maintenance and adjustments
Periodic inspection, adjustment, and lubrica-
tion will keep your watercraft in the safest and
most efficient condition possible. Safety is an
obligation of the watercraft owner. Proper
maintenance must be carried out to keep the
exhaust emission and sound levels within the
regulated limits. The most important points of
watercraft inspection, adjustment, and lubri-
cation are explained on the following pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories de-
signed 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 re-
pair establishment or individual. Warranty
repair, however, must be performed at an
authorized Yamaha marine dealership.
WARNING
EWJ00311
Be sure to turn off the engine when you

specified. If you are not familiar with ma-
chine servicing, this work should be done
by a Yamaha dealer or other qualified me-
chanic.
