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, wa-
ters, and wildlife with respect and courtesy.
Whenever and wherever you ride, think of
yourself as the guest of those around you. Re-
member, for example, that the sound of your
watercraft may be music to you, but it could be
just noise to others. And the exciting splash of
your wake can make waves others won’t en-
joy.
Avoid riding close to shoreline homes and wa-
terfowl nesting areas or other wildlife areas,
and keep a respectful distance from fisher-
men, other boats, swimmers, and populated
beaches. When travel in areas like these is
unavoidable, ride slowly and obey all laws.
Proper maintenance is necessary to ensure
that the exhaust emission and sound levels of
your watercraft will continue to be within regu-
lated limits. You have the responsibility to
make sure that the recommended mainte-
nance in this owner’s/operator’s manual is
carried out.
Remember, 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 refueling. And
keep your surroundings pleasant for the peo-
ple 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 enjoyment of a
variety of recreational opportunities.

To enhance particular types of performance,
select bow down or bow up.
EJU31330Bow down
Turn the QSTS selector to (a) or (b) and the
bow will go down while the watercraft is on
plane.
Bow down puts more of the bow in the water.
This gives the watercraft more “hook”, which
enhances turning performance. This position
will also help the watercraft get up on plane
more quickly.
At higher speeds, however, the watercraft will
have a greater tendency to “bow steer” and
follow waves and wakes in the water. Fuel
economy and maximum speed are also re-
duced.
EJU31340Bow up
Turn the QSTS selector to (c) or (d) and the
bow will go up while the watercraft is on plane.Bow up puts less of the bow in the water.
There is less water resistance, so straight-
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the watercraft
may tend to “porpoise” (hop in the water). If
the watercraft is porpoising, select neutral or
bow down.
EJU31350Handgrip
The handgrip provides a handhold for board-
ing the watercraft.
WARNING
EWJ00020
Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.
EJU34870Bow eye
The bow eye is located at the bow of the wa-
tercraft.

The bow eye is used to attach a rope to the
watercraft when transporting, mooring, or
towing it in an emergency.
EJU36020Stern rope holes
The stern rope holes are located at the stern
of the watercraft.
The stern rope holes are used to attach a rope
to the watercraft when transporting or moor-
ing it.
EJU31370Yamaha Engine Management System
(YEMS)
This model is equipped with an integrated,
computerized management system that con-
trols and adjusts ignition timing, fuel injection,
engine diagnostics, and the off-throttle steer-
ing (OTS) system.
EJU31420Multifunction information center
This meter contains the following functions for
help and convenience in operating the water-
craft.
CAUTION:
ECJ00060
Do not run the engine over 4000 r/min
when checking the operation of the
meter on land without supplying water,
otherwise the engine could overheat
and the catalytic converter could be se-
riously damaged.
Use the specified resistor-type spark
plugs and caps, otherwise the meter
may function erratically.
NOTE:
When the engine is started, all displays light
up for a few seconds, the buzzer sounds
twice, and then the meter starts to operate
normally.
