Battery
Check the battery condition and the elec-
trolyte level.
Check that the battery leads are tightened
securely and there is no corrosion on the
battery terminals.
WARNING@
The battery must always be fully
charged and in good condition. Loss
of battery power may leave you
stranded. Never operate the watercraft
if the battery does not have sufficient
power to start the engine or if it shows
any other signs of decreased power.

Be sure to connect the breather hose
to the battery. Fire or explosion could
result if the breather hose is damaged,
obstructed, or not connected properly.
@
Make sure that the battery is securely
held in place.

5. While lightly squeezing the throttle lever,
push the start switch (green button).
WARNING@ On this watercraft, the engine is con-
nected directly to the jet pump. Starting
the engine immediately generates some
thrust. Apply only enough throttle to
keep the engine running.
@
6. Release the start switch as soon as the
engine starts to run.
CAUTION:@
Never push the start switch while the
engine is running.

Do not operate the start switch for
more than 5 seconds, otherwise the
battery will be discharged and the
engine will not start. Also, the starter
motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
try again.
@
7. After the engine has warmed up, push
the choke knob in to its original position.
NOTE:@ If the choke knob is left pulled out, the
engine will stall.

Battery
If the watercraft will not be used for more
than a month, disconnect the negative (–)
lead first, then the positive (+) lead and
breather hose, and then remove the battery
from the watercraft.
Clean the battery casing using fresh
water.
If the battery terminals are dirty or cor-
roded, clean them with a wire brush.
Fully charge the battery, and then store it
in a cool, dark place.
Apply Yamaha marine grease or Yamaha
grease A to the battery terminals.
Check the battery at least every 2 months
and fully charge it if necessary.
WARNING@ Be sure to connect the breather hose to
the battery. Fire or explosion could result
if the breather hose is damaged,
obstructed, or not connected properly.
@
CAUTION:@ The battery may not be usable again if
you store it for a long period without
charging it. Charge the battery periodi-
cally.

NOTE:@ The condition of the battery can be known
by checking the specific gravity of the elec-
trolyte. However, you can also know the con-
dition of the battery by measuring 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 to charge the
battery. If you maintain the battery yourself,
be sure to read and follow the instructions
provided with the battery tester and charger
you use.

fresh water. Drain off all water and wipe
up remaining moisture with clean, dry
rags.
3. Spray the engine’s exterior with a rust
inhibitor and lubricant.
4. Wax the hull with a non-abrasive wax.
5. Wipe all vinyl and rubber components,
such as the seat and engine compart-
ment seals, with a vinyl protectant. Specific gravity (for reference):
