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 distress signals on board is recommended 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.
ADDITIONAL EQUIPMENT
RECOMMENDATIONS
The following equipment can help
make your boating experience safer
and more enjoyable:
● Moor ing 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
boat hook on the other end)
● Spare parts, such as an extra set of
spark plugs and fuses
● Navigation charts for the waters
where you will be boating
● Tow rope
● Navigation Lights:
Your Jet Boat is equipped with navigation lights for use between sunset 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 information).

APPAREL
● Because of the drowning hazards
associated with water sports, the
operator and passengers must
always wear a U.S. Coast Guardapproved vest-type personal flotation
device (PFD). Be sure the PFD is
properly fitting and in good condition.
● You should consider wearing slipresistant 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 hazards could cause severe injuries to
certain body orifices (rectum and
vagina).
● 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 protection. 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 techniques well, before attempting more
difficult maneuvers.Your Jet Boat is
capable of truly exhilarating performance. Don’t push your boat to the
limits beyond your ability. The operator 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 consuming alcohol or taking drugs.
● Depending upon operating conditions, 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.
1-9

● Always perform the pre-operation
checks on page 3-4 before operating 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 tangled in the controls which would prevent the lanyard from pulling away.
AFETYINFORMATION
● 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.
To prevent accidental starting of the
engine, always remove the lanyard
from the stop switch when the
engine is not running.
● Always watch carefully for swimmers. 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.

● 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 r ide 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 thr ust 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 cannot 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 propelled. 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 ejected, 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 maneuvering, 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.

● 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.
AFETYINFORMATION
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 board from the rear, use
swim platform, or swim behind boat
when engines are running. Strong
streams of water from the jet nozzles can be dangerous and can
result in serious injury when directed at body orifices (rectum and
vagina).
● Never insert any object in the jet
pump outlet.

Be alert to the possibility of adverse
weather.Take note of marine weather forecasts and the prevailing
weather conditions before setting
out in your Jet Boat.
● Leave a “float plan” with a responsible 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 ha v e
both bow and stern lights operating.
When at anchor in the dark, the
stern light must be lit.See page 2-12

WATERSKIING
You can use the Jet Boat to tow a
waterskier, using the tow eye provided.
Do not attach the tow rope to any other
location on the boat.
It is the boat operator’s responsibility to
be alert to the safety of the waterskier
and others. Know and follow all state
and local waterskiing regulations in
effect for the waters in which you will
be operating. The following are some
important considerations for minimizing risks while waterskiing:
● Wear an approved PFD, preferably
a brightly colored one so boat operators can see you.

the boat. A wetsuit can also help
protect against hypothermia (low
body temperature) and abrasions.
● A second person should be on
board as an observer to watch the
skier; in most states it is required by
law. Let the skier direct the operator’s control of boat speed and
direction with hand signals. The
observer should sit securely in the
seat, hold onto the handles or
straps provided, and place feet firmly on the floor for proper balance
while facing to the rear to watch the
skier’s hand signals and condition.
The front, port-side seat has a handle for a backward-facing obser ver.
● When preparing to pull a skier,
operate the Jet Boat at the slowest
possible speed until the boat is well
away from the skier and slack in the
tow rope is taken up. Be careful that
the rope is not looped around anything.After checking that the skier is
ready and to be sure there is no traffic or obstacles, apply enough throttle to raise the skier.

● Make smooth, wide turns. The Jet
Boat is capable of very sharp turns
which could exceed the abilities of
the skier. Keep the skier at least

BASIC BOATING
RULES
RULES OF THE ROAD
Your Yamaha Jet Boat is legally considered a power boat.Operation of the Jet
Boat must be in accordance with the
rules and regulations governing the
waterway on which it is used.
Just as there are rules which apply
when you are driving on streets and
highways, there are waterway rules
which apply when you are operating
your Jet Boat. These rules are used
internationally, and are also enforced
by the United States Coast Guard and
local agencies.You should be aware of
these rules, and follow them whenever
you encounter another vessel on the
water.
Several sets of rules prevail according
to geographic location, but are all basically the same as the International
Rules of the Road.The rules presented
here in your Owner's Manual are condensed, and have been provided for
your convenience only. Consult your
local U.S. Coast Guard Auxiliary or
Department of Motor Vehicles for a
complete set of rules governing the
waters in which you will be using your
Jet Boat.
STEERING AND SAILING RULES
AND SOUND SIGNALS
Whenever two vessels on the water
meet one another, one vessel has the
right-of-way; it is called the "stand-on"
vessel.The vessel which does not have
the right-of-way is called the "give-way
or "burdened" vessel. These rules determine which vessel has the right-ofway, and what each vessel should do.
Stand-On Vessel
The vessel with the right-of-way has
the duty to continue its course and
speed, except to avoid an immediate
collision. When you maintain your
direction and speed, the other vessel
will be able to determine how best to
avoid you.
Give-Way V essel
The vessel which does not have the
right-of-way has the duty to take positive and timely action to stay out of the
way of the Stand-On vessel. Normally,
you should not cross in front of the vessel with the right-of-way. You should
slow down or change directions briefly
and pass behind the other vessel.You
should always move in such a way that
the operator of the other vessel can
see what you are doing.
The General Prudential Rule regarding
the right-of-way is that if a collision
appears unavoidable, neither boat has
the right-of-way. Both boats must avoid
the collision.
In other words, follow the standard
rules except when a collision will occur
unless both vessels try to avoid each
other. If that is the case, both vessels
become "Give-Way" vessels.

S
AFETYINFORMATION
RULES WHEN ENCOUNTERING
VESSELS
There are three main situations which
you may encounter with other vessels
which could lead to a collision unless
the Steering Rules are followed:
Meeting (you are approaching another
vessel head-on)
Crossing (y ou are tra velling across the
other vessel's path)
Overtaking (you are passing or being
passed by another vessel)
In the following illustration, your Jet
Boat is in the center. You should give
the right-of-way to any vessels shown
in the white area (you are the GiveWay vessel). Any vessels in the shaded area must yield to you (they are the
Give-Way vessels). Both you and the
meeting vessel must alter course to
avoid each other.
Meeting
If you are meeting another power vessel head on, and are close enough to
run the risk of collision, neither of you
has the right-of-way.Both of you should
alter course to avoid an accident. You
should keep the other vessel on your
port (left) side.This rule doesn't apply if
both of you will clear one another if you
continue on your set course and
speed.
Crossing
When two power driven vessels are
crossing each other's path close
enough to run the risk of collision, the
vessel which has the other on the starboard (right) side must keep out of the
way of the other. If the other vessel is
on your right, you must keep out of its
way; you are the Give-Way vessel. If
the other vessel is on your port (left)
side, remember that you should maintain course and direction, provided the
other vessel gives you the right-of-way
as it should.
1-16
S
AFETYINFORMATION

STAND-ON-VESSEL
GIVE-WAY-VESSEL
Overtaking
If you are passing another vessel, you
are the "Give-Way" vessel.This means
that the other vessel is expected to
maintain its course and speed. You
must stay out of its way until you are
clear of it. Likewise, if another vessel is
passing you, you should maintain your
speed and direction so that the other
vessel can steer itself around you.
Narrow Channels and Bends
When navigating in narrow channels,
you should keep to the right when it is
safe and practical to do so. If the operator of a power-driven vessel is preparing to go around a bend that may
obstruct the view of other water vessels, the operator should sound a prolonged blast on the horn (4 to 6 seconds). If another vessel is around the
bend, it too should sound the horn.
Even if no reply is heard, however, the
vessel should still proceed around the
bend with caution.
Fishing Vessel Right-of-Way
All vessels which are fishing with nets,
lines or trawls are considered to be
"fishing vessels" under the
International Rules. Vessels with
trolling lines are not considered fishing
vessels. Fishing vessels have the rightof-way regardless of position. Fishing
vessels cannot, however, impede the
passage of other vessels in narrow
channels.
GIVE-WAY
VESSEL
OTHER SPECIAL SITUATIONS
There are three other rules you should
be aware of when driving your Jet Boat
around other vessels.
Sailing Vessel Right-of-Way
Sailing vessels should normally be
given the right-of-way. The exceptions
to this are:
1. When the sailing vessel is overtaking the power-driven vessel, the
power-driven vessel has the rightof-way.
2. Sailing vessels should keep clear of
any fishing vessel.
3. In a narrow channel, a sailing vessel
should not hamper the safe passage of a power-driven vessel
which can navigate only in such a
channel.

Reading Buoys and Other Markers
The waters of the United states are
marked for safe navigation by the lateral system of buoys. Simply put, buoys
and markers have an arrangement of
shapes, colors, numbers and lights to
show which side of the buoy a boater
should pass on when navigating in a
particular direction. The markings on
these buoys are oriented from the perspective of being entered from seaward
(the boater is going towards the port).
This means that red buoys are passed
on the starboard (right) side when proceeding from open water into port, and
black buoys are to por t left) side. When
navigating out of port, your position with
respect to the buoys should be
reversed; red buoys should be to port
and black buoys to starboard.
Many bodies of water used by boaters
are entirely within the boundaries of a
particular state. The Uniform State
Waterway Marking System has been
devised for these waters. This system
uses buoys and signs with distinctive
shapes and colors to show regulatory
or advisory information.These markers
are white with black letters and orange
borders. They signify speed zones,
restricted areas, danger areas, and
general information.
Remember, markings may vary by
geographic location. Always consult
local boating authorities before driving
your Jet Boat in unfamiliar waters.

ENJO Y YOUR JET
BOAT RESPONSIBLY
You share the areas you enjoy when
operating your Jet Boat with others and
with nature. So your enjoyment
includes a responsibility to treat other
people, and the lands, waters, and
wildlife with respect and courtesy.
Whenever and wherever you operate
your Jet Boat, think of yourself as the
guest of those around you.Remember,
for example, that the sound of your Jet
Boat 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 enjoy. Avoid boating close
to shoreline homes and waterfowl nesting areas or other wildlife areas, and
keep a respectful distance from fisherman, other boats, swimmers, and populated beaches. When travel in areas
like these is unavoidable, drive 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.And keep your surroundings pleasant for the people and
wildlife that share the waterways: don’t
litter!
When you use your Jet Boat responsibly, with respect and courtesy for others, you help ensure that our waterways stay open for the enjoyment of a
variety of recreational opportunities.
