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.

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.
EJU33762
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.
