●Do not attempt to modify this watercraft!
Modifications to your watercraft may
reduce safety and reliability, and render
the watercraft unsafe or illegal for use.
●Attach the engine shut-off cord (lanyard)
to wrist and keep it free from the handle-
bars so that the engine stops if the opera-
tor falls off. After riding, remove the
engine shut-off cord from the watercraft to
avoid accidental starting or unauthorized
use by children or others.
●Scan carefully for swimmers and stay
away from swimming areas. Swimmers
are hard to see and you could acciden-
tally hit someone in the water.
●Avoid being hit by another boat! You
should always take the responsibility to
watch for traffic; other boaters may not be
watching for you. If they do not see you,
or you maneuver more quickly than other
boaters expect, you risk a collision.
●Maintain a safe distance from other boats
or watercraft, and also watch for boats’ ski
ropes or fishing lines. Obey the “Safe
boating rules” and be sure to check
behind you before making a turn. (See
Safe boating rules on page 1-14.)

Hazard information
●When transporting or storing your water-
craft, always place the fuel cock knob in
the “OFF” position, otherwise gasoline
may overflow from the carburetor.
●Never start the engine or let it run for any
length of time in an enclosed area.
Exhaust fumes contain carbon monoxide,
a colorless, odorless gas that may cause
loss of consciousness and death within a
short time. Always operate the watercraft
in an open area.

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.

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.
