Safe boating rules
Your Yamaha watercraft is legally considered
a powerboat. Operation of the watercraft must
be in accordance with the rules and regula-
tions governing the waterway on which it is
used.
EJU30991
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. Dis-
pose of water and any fuel and oil residue in
the engine compartment according to local
regulations. 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

push the rear of the seat down to lock it in
place.
(2) Install the rear seat. Make sure that the
seats are securely installed before oper-
ating the watercraft.
EJU31063Hood
To open the hood, push the hood latch, and
then lift up the hood.To close the hood, push down on the rear of
the hood until it latches securely. Make sure
that the hood is securely closed before oper-
ating the watercraft.
EJU36691Fuel tank filler cap
The fuel tank filler cap is located under the
hood.
To remove the fuel tank filler cap, open the
hood, and then turn the cap counterclockwise.
(See page 24 for hood opening and closing
procedures.)
To install the fuel tank filler cap, turn it clock-
wise until it stops. Make sure that the fuel tank
filler cap and the hood are securely closed be-
fore operating the watercraft.

The Yamaha Security System and low-RPM
mode settings are selected using the remote
control transmitter. (See “Yamaha Security1Hood latch

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.
EJU37380Reboarding grip
The reboarding grip provides a handhold for
boarding the watercraft.
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.

EJU37250Information display
The information display shows watercraft op-
erating conditions.
EJU37261Hour meter/voltmeter
The hour meter/voltmeter can be used as an
hour meter or a voltmeter.
TIP:
The hour meter is selected at the Yamaha
factory.
Hour meter
The hour meter shows the hours of engine op-
eration that have elapsed since the watercraft
was new.To switch to the hour meter from the voltme-
ter:
Push the “Hour Volt” button for at least 1 sec-
ond. The display switches from the voltmeter
to the hour meter.
Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.
If the battery voltage has dropped significant-
ly, “LO” is displayed on the voltmeter. If the
battery voltage has risen significantly, “HI” is
displayed. If “HI” or “LO” is displayed, immedi-
ately return to shore and have a Yamaha
dealer service the watercraft.
