Safe boating rules
Your Yamaha watercraft is legally consid-
ered a powerboat. Operation of the water-
craft must be in accordance with the rules
and regulations governing the waterway on
which it is used.
EJU00322
Enjoy your watercraft
responsibly
You share the areas you enjoy when
riding your watercraft with others and with
nature. So your enjoyment includes a
responsibility to treat these other people,
and the lands, waters, and wildlife with
respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you.
Remember, for example, that the sound of
your watercraft may be music to you, but it
could be just noise to others. And the excit-
ing splash of your wake can make waves
others won’t enjoy. Avoid riding close to
shoreline homes and waterfowl nesting
areas or other wildlife areas, and keep a
respectful distance from fishermen, other
boats, swimmers, and populated beaches.
When travel in areas like these is unavoid-
able, ride slowly and obey all laws.
Remember that pollution can be harmful
to the environment. Do not refuel or add oil
where a spill could cause damage to nature.
Remove your watercraft from the water and
move it away from the shoreline before refu-
eling. And keep your surroundings pleasant
for the people and wildlife that share the
waterways: don’t litter!
When you ride responsibly, with respect
and courtesy for others, you help ensure
that our waterways stay open for the enjoy-
ment of a variety of recreational opportuni-
ties.

Cooling water pilot outlet
This watercraft is equipped with a cooling
water pilot outlet on the port (left) side of the
watercraft.
When the engine is running, cooling
water is circulated in the engine, and then it
is discharged from the pilot outlet. To check
for proper operation of the cooling system,
check that water is being discharged from
the pilot outlet. If water is not being dis-
charged from the outlet, cooling water may
not be circulating in the engine. When this
occurs, stop the engine and check for the
cause. (See pages 2-9 and 5-3 for further
instructions.)
NOTE:@If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlet after the engine is started.

EJU00356
Steering system
Your watercraft can be steered by turning
the handlebars 1 the same direction you
wish to travel. When the handlebars are
turned, the angle of the jet thrust nozzle 2
is changed, and the direction of the water-
craft is changes accordingly. Since the
strength of the jet thrust determines the
speed and direction of a turn, the throttle
must always be open when attempting a
turn, except at trolling speed.
