SEVERE INJURY OR DEATH MAY
RESULT IF YOU IGNORE ANY OF
THE FOLLOWING SAFETY INFOR-
MATION.
●Before operating the Jet Boat, read
this entire manual, the Operation
Instruction card, and all warning
labels on the Jet Boat.Also view the
Basic Orientation video tape.These
materials should give you an under-
standing of the boat and its opera-
tion.
Never allow anyone to operate this
Jet Boat until they too have read this
Owner's Manual, the Operation
Instruction card, and all warning
labels.
LIMITATIONS ON WHO MAY
OPERATE THE JET BOAT
●This boat is recommended only for
operators 16 and older with a valid
boat license.
Even though a motor vehicle opera-
tor's license is not required for Jet
Boat operation in most states, it is
one indicator that the operator has
previously demonstrated a reason-
able degree of maturity, responsibil-
ity, and good judgment.
A responsible adult must supervise
operation of this boat by minors.
Many states have minimum age and
education requirements. Always
check state and local boating laws
before you operate the Jet Boat.
●Your Jet Boat is designed to carry
the operator, up to four passengers,
and cargo, as long as the total
weight does not exceed the maxi-
mum load capacity. Never have
more than five people on board.
Weight distribution affects perfor-
mance. Keep weight in the boat low
and evenly distributed. Remove any
unnecessary cargo and store it on
shore.
ATTENTION:__________________
Maximum load capacity: 930 lb
(421 kg)
Includes weight of operator, passen-
gers, and any cargo.

SAFETY INFORMATION

REQUIRED EQUIPMENT
The U.S. Coast Guard (USCG) has
regulations which describe minimum
standards of safety. You must comply
with these regulations, which apply to
boats like your Jet Boat which are less
than 26 feet long.
●Personal Flotation Devices (PFDs):
Type I, II, or III as required for all
people on board (see “Apparel” for
more information), plus at least one
Type IV (throwable type).
●Fire Extinguisher:
At least one B-1 type hand-held
portable fire extinguisher.
●Visual Distress Signals:
Having USCG-approved visual dis-
tress signals on board is recom-
mended under all circumstances,
and required if you will be operating
on coastal waters, the Great Lakes,
territorial seas and waters connected
to them. Contact your dealer or the
Coast Guard for more information.
●Sound Signalling Device:
Your Jet Boat is equipped with a
horn which can be used to signal
other boats. See “Rules of the
Road” for more information.
●Navigation Lights:
Your Jet Boat is equipped with nav-
igation lights for use between sun-
set and sunrise, and during periods
of reduced visibility, such as fog. Be
sure these lights are working and
are turned on when necessary (see
page 2-12 and 3-9 for more infor-
mation).
ADDITIONAL EQUIPMENT
RECOMMENDATIONS
The following equipment can help
make your boating experience safer
and more enjoyable:
●Mooring fenders and lines
●Anchor with suitable line (a
“Danforth” type anchor and line that
is at least 6-times the depth of the
water where you will drop anchor
are recommended)
●Manual-type bilge pump
●First Aid kit
●Waterproof Flashlight with extra
batteries
●Tool kit with assorted screwdrivers,
pliers, wrenches (including metric
sizes), and electrical tape
●Oar or paddle (look for one with a

SAFETY INFORMATION

APPAREL
●Because of the drowning hazards
associated with water sports, the
operator and passengers must
always wear a U.S. Coast Guard-
approved vest-type personal flotation
device (PFD). Be sure the PFD is
properly fitting and in good condition.
●You should consider wearing slip-
resistant deck shoes or water shoes
for more secure footing while boating.
●Waterskiers and others engaging in
water sports behind the boat must
wear a wetsuit. A wetsuit can help
protect against strong streams of
water from the jet nozzles or impact
from the water surface. These haz-
ards could cause severe injuries to
certain body orifices (rectum and
vagina).
●Depending upon operating condi-
tions, you may consider wearing a
wetsuit while boating. A wet suit can
help protect against hypothermia
(low body temperature) when there
is water spray coming into the boat,
particularly if you are operating in
cold water or air temperature.
●You might also consider gloves
designed for water sports to help
protect hands during operation, as
well as while launching and docking
your boat.
●You may want to consider eye pro-
tection. Water spray could get in
your eyes in some circumstances
which could affect your vision.
OPERATIONAL REQUIREMENTS
●Operating your Jet Boat requires
skills acquired only through practice
over a period of time. Take the time
to learn the basic operating tech-
niques well, before attempting more
difficult maneuvers.Your Jet Boat is
capable of truly exhilarating perfor-
mance. Don’t push your boat to the
limits beyond your ability. The oper-
ator should have at least 10 hours
of experience with the boat before
any abrupt acceleration, sharp
turns, or operation at full speed.
●NEVER operate the boat after con-
suming alcohol or taking drugs.

1-9
SAFETY INFORMATION

●Always perform the pre-operation
checks on page 3-4 before operat-
ing to be sure your equipment is
working properly.
●The operator should always attach
the engine stop switch lanyard
(cable) to his PFD so that the
engines will stop if the operator
accidentally leaves the helm.Failure
to attach the lanyard could result in
a runaway boat if the operator is
ejected.
Be sure the lanyard is not wrapped
around the steering wheel or tan-
gled in the controls which would pre-
vent the lanyard from pulling away.
To prevent accidental starting of the
engine, always remove the lanyard
from the stop switch when the
engine is not running.
➀Engine stop switch
➁Engine stop switch lanyard
➂Lanyard clipped to PFD
●Passengers must always sit in a
designated seating area, place feet
on the deck, and use the hand grips
provided while the boat is in motion.
UNDERWAY SEATING POSITIONS
MAXIMUM 5 PERSONS
●Always watch carefully for swim-
mers. Stay away from swimming
areas. Swimmers are hard to see
and you could accidentally hit
someone in the water.
●Avoid being hit by another boat!
Always watch for traffic; other
boaters may not be watching for
you. If they don't see you, or you
maneuver more quickly than other
boaters expect, you risk a collision.

SAFETY INFORMATION

➁➂

●Maintain a safe distance from other
boats or watercraft, and also watch
for boat's ski ropes or fishing lines.
Obey the "Rules of the Road" (see
page 1-15), and be sure to check
behind you before making a turn.
●If you are pregnant or in poor
health, ask your doctor's advice on
whether it is safe for you to ride this
Jet Boat.
●Do not attempt to modify this Jet
Boat! Modifications to your boat may
reduce safety and reliability, and
may make the boat illegal for use.
JET BOAT CHARACTERISTICS
●Jet thrust turns the Jet Boat. If you
are going faster than idle speeds,
you must use engine power to turn.
If you pull the throttle levers back to
idle or shut off the engines, you can-
not turn – even if you turn the wheel.
Practice turning in an open area
without obstructions until you have
a good feel for this maneuver.
Yamaha Jet Boats are water-jet pro-
pelled. The jet pumps are directly
connected to the engines. This
means that jet thrust will produce
some boat movement whenever the
engine is running. The Jet Boat has
a "neutral" position, but since the
Jet Boat is always producing thrust
while engines are running, some
forward or reverse movement may
occur.
●Boats, including your Jet Boat, do
not have brakes. Pull the throttle
levers back to idle or stop the
engines and allow water resistance
to slow the boat down. Remember,
however, that you have no steering
control without throttle. Do not use
Reverse to try to slow down from
speed, because you could be eject-
ed, the boat could be flooded, or
damage could occur to the shift
mechanism.
Reverse can be used to slow down
or stop during slow-speed maneu-
vering, such as when docking.Once
the engines are idling, shift to
Reverse and gradually increase
engine speed to slow down or stop.
●Keep the following in mind when
using reverse:
Reverse is for launching and low
speed maneuvering only. Shift only
when the engines are idling or off.
Do not shift while applying throttle.
Make sure there are no obstacles or
people behind you before shifting
into reverse.

SAFETY INFORMATION

●Keep hands, feet, hair, and all other
parts of your body and clothing
away from jet intakes on the bottom
of the hull while engine is running
because they could be caught in the
intake. Stop the engine and remove
the lanyard before removing any
debris or weeds which may have
collected around the jet intake.
Refer to the Jet Pump Clean-Out
procedures on page 5-4 for further
information.
●Do not board from the rear, use
swim platform, or swim behind boat
when engines are running. Strong
streams of water from the jet noz-
zles can be dangerous and can
result in serious injury when direct-
ed at body orifices (rectum and
vagina).
●Never insert any object in the jet
pump outlet.
CRUISING LIMITATIONS
●Do not try to jump other boat's
wakes or follow another boat or
watercraft too closely or you will
increase your chance of colliding
with other boats. Do not go over a
water-ski jump, or attempt any other
kind of jumping maneuver with the
boat, since you risk injuring yourself
or damaging your Jet Boat.
●Watch for dangerous underwater
obstacles when boating in shallow
water. Never operate in water that is
less than 3 ft (90 cm) deep.
●Do not operate the boat in rough
water, bad weather or when visibili-
ty is poor; this may lead to an acci-
dent causing injury or death.
Operation in rough water can crack
the hull or damage internal parts.

Be alert to the possibility of adverse
weather.Take note of marine weath-
er forecasts and the prevailing
weather conditions before setting
out in your Jet Boat.
●Leave a “float plan” with a responsi-
ble person on shore. Tell where you
plan to go and when you plan to
arrive, and provide a description of
your boat. Advise this person if your
plans change and also when you
arrive to prevent false alarms. A
sample float is included on page 6-6.
NIGHT OPERATION
●When using your Jet Boat before
dawn and after dusk, you must have
both bow and stern lights operating.
When at anchor in the dark, the
stern light must be lit.See page 2-12
for instructions.
