Important Safety Information!
Your safety, as well as the safety of others with and around
you, is a direct result of how you operate and maintain your
boat. Read and comprehend this manual. Make sure that
you understand all the controls and operating instructions
before attempting to operate the boat. Improper operation
is extremely dangerous.
The basic safety rules are outlined in this section of the manual.
Additional precautions throughout the manual are noted by
the following symbols:
This symbol indicates a potentially hazardous circumstance,
which, if not avoided, may result in minor or moderate injury.
It may also be used to alert against unsafe practices.
This symbol indicates a potentially hazardous situation, which,
if not avoided, could result in death or serious injury.
This symbol indicates an imminently hazardous situation,
which, if not avoided, will result in death or serious injury.
This is limited to the most extreme situations.
The precautions listed in this manual and on the boat are
not exhaustive. If a procedure, method, tool or part is not
specically recommended by Skier’s Choice, you must satisfy
yourself that it is safe for you and others, and that the boat will
not be damaged or made unsafe as a result of your decision.
REMEMBER: ALWAYS USE COMMON SENSE WHEN OPERATING,
SERVICING OR REPAIRING THE BOAT!
In addition to everyday safety, failure to observe safety
recommendations may result in severe personal injury or death to
you or to others. Use caution and common sense when operating
your boat. Don’t take unnecessary chances!
Be certain that all boat passengers are aware of this information
and conform to boat safety principles.

Safe Boating
Safe boating practices may seem obvious, but people have thought up
risky and dangerous activities in boats, with boats, and behind boats.
Just because you or your passengers have seen a boating maneuver
performed or have seen a particular activity promoted, do not assume
there is no risk of injury or death. Before you or your passengers go
out in the boat and engage in any water sport activity, give careful
consideration to the risks. Plan ahead. Think twice before you try
something new behind your boat or with your boat. Know the limits
of you, your passengers and your equipment and do not exceed them.
In addition to careful review of this manual, you should be aware
as well that there are many sources of information available. Skier’s
Choice urges you to pursue additional training, such as safety and
seamanship courses oered by the U.S. Coast Guard Auxiliary and the
U.S. Power Squadron.
Safe boating and safe actions may seem obvious, yet every year US
Coast Guard statistics give evidence that many people disregard safe
boating practices. Do not take safety for granted.Think twice.We want
all our boat owners and their passengers, friends, and families to have
a safe and enjoyable experience on the water.

Safety Equipment
Your Supra has been equipped at the factory with most of the
federally required safety equipment for inland waters (Class 1,
16’-to-26’). This equipment includes:
• UL-approved Marine Fire Extinguisher, Type A-BC (2 lbs.)
good for solids, liquids, and electrical re
• ABYC-approved Marine Muers with water injection
• USCG-approved Marine Flame Arrestor
• USCG-approved Engine Box Ventilation with sparkless
power blower
• ABYC-approved Electric Horn sound warning device
• USCG-approved inland lighting
Federal law also requires at least one Type I, II or III Personal
Flotation Device (PFD) for each person on board or being towed
on water skis or other recreational equipment. In addition, one
throwable Type IV PFD must also be on board. As the owner,
obtaining the appropriate PFDs is your responsibility. Your
Supra dealer can and will be happy to assist you.
NOTE: Requirements for coastal waters and inland waters
dier. Check with the local authorities for more information.
Water Sports Names and Terminology
There are many types of towed water sports, and they are
known by many dierent names. The more popular sports
are wakeboarding, waterskiing, surfing, wakeskating and
tubing. And there are many others. The terms used to describe
participants in towed water sports activities also vary greatly.
Typical terms include rider, skier, and wakeboarder. To keep the
language in this manual straightforward, we use rider or skier
to refer to a participant in any towed water sport. The terms ski,
skiing, riding, surng or wakeboarding are used to refer to any
towed water sport.
National Marine Manufacturers Association
231 S. LaSalle Street, Suite 2050, Chicago, IL. 60604

Federal law requires certain safety equipment to be onboard
at all times. In addition, responsible boaters carry other
equipment in case of emergency. Check with the local boating
authorities for any additional requirements over and above
the federal stipulations.

Failure to adhere to these precautions may result in severe injury
or death to you and/or others.
• Improper operation is extremely dangerous. Operators must read
and understand all operating manuals supplied with the boat
before operation.
• Remain seated at all times while the boat is in motion.
• Never stand or allow passengers to stand while the boat is moving.
You or others may be thrown from the boat.
• Children in the bow of the boat should be accompanied by an
adult at all times.
• Never operate the boat while under the inuence of alcohol or
drugs.
• On-board equipment must always conform to the governing
federal, state, and local regulations.
• Gasoline vapors can explode. Before starting engine, open engine
box, check engine compartment for gasoline vapors, and operate
blower for at least four minutes. Run blower below cruising speed.
• Leaking fuel is a re and explosion hazard. Inspect system regularly.
Examine fuel tanks for leaks or corrosion at least annually.
• Never override or modify the engine safety shut-o switch or
engine neutral starting safety switch in any way.
• Never remove or modify components of the fuel system in any way
except for maintenance by qualied personnel. Tampering with
fuel components may cause a hazardous condition.
A smart owner will avoid potential problems on an outing by
having additional equipment on board. Normally, this equipment is
dependent on the body of water and the length of the trip.
We suggest the following—as a minimum. Your Supra dealer can also
assist you with additional recommendations.
• An anchor with at least 75 feet of line
• A manual bailing device for removing water
• A combination oar/boat hook
• A day-and-night visual distress signal
• A rst aid kit and manual
• An airway breathing tube
• A waterproof ashlight
• A set of local navigation charts
• Mooring lines and fenders
• Extra engine oil
• A tool kit
• A portable AM/FM radio or weather radio
• VHF hand held marine radio
• Cell Phone
Boating-related accidents are generally caused by the operator’s failure
to follow basic safety rules or written precautions. Most accidents
can be avoided if the operator is completely familiar with the boat, its
operation, and can recognize potentially hazardous situations before
an accident occurs.

Carbon Monoxide (CO) Safety
Carbon monoxide is a colorless, odorless and tasteless gas. It is
produced by gasoline engines and is a component of exhaust fumes.
Shut o the engine when people are on the swim platform or in the
water around the rear of the boat.
Do not do any other activities which puts people in close proximity of
the transom when the engine is running.
For the most current information on carbon monoxide, you may

Water Sports Safety
Riders are obligated to be as aware of the fundamental safety rules as
well as the boat operator. If you are new to towed water sports, seek
certied training before starting. You will nd it especially helpful to
join a local ski club and USA Waterski when possible.
Always remember that the majority of water sports injuries are the
result of impacts with other objects, so always look where you are
going and be aware of what is going on around you.
Failure to adhere to these warnings may result in severe injury or death to you
and/or others.
• Every skier must always wear a USCG-approved personal otation device.
• Maintain a distance of at least 100 feet from all other objects, including
other boats, piers, rafts, mooring and navigational buoys, pilings, abutments,
or any other items.
• Always have an experienced driver and observer in the boat when skiing.
• Never ski in shallow water, close to shore, or in water where you do not
know the depth or what is beneath the surface.
• Never put your arm, head, or any other part of your body through the handle-
bridle of the ski line nor wrap the line around any part of the body at any time.
• Never ski at night, or directly in front of other boats.
• Never jump from a boat that is moving at any speed, nor enter or exit the
water when the engine is running (ON).
• Make sure that everyone knows and uses approved skiing hand signals and
common skiing courtesy.

Product Misuse
Misuse of the product or use of it in a manner for which it was
never intended can create dangerous situations.The driver and
passengers are responsible for using the product safely and as
intended. The driver must operate the boat in a manner that
ensures the safety of all passengers. If you or your passengers
are unsure about use of the product, about performing certain
boating maneuvers or are unsure about a particular water
activity, refer to this manual or contact a knowledgeable source
such as your local dealer, Skier’s Choice, Inc., the US Coast Guard,
or your local boating authority.
Capacity and Weighting Your Boat
Do not exceed the capacity warning label axed to the boat
in the helm area. The capacity limit is shown in the number of
people and weight limit in pounds. The combined weight of
people and gear must be considered when loading the boat.
Factory ballast and fuel have been considered in the capacity
limit and do not need to be added to the people and gear
weight. Ballast weight above factory installed equipment must
be calculated into the total weight of people and gear.
Although water intrusion and waves spilling inside a boat is
an obvious boating hazard, this hazard can increase when
weighting your boat for water sports such as wakeboarding
or wakesurng. Do not overweight the boat or exceed boat
capacity. Use good judgment when using unbalanced weight
in your boat. Concentrating weight in a rear corner of the boat
for wakesurng puts the top of the deck closer to water level.
Backwash, large waves and choppy water are more likely to
swamp the boat in this situation.
When loading your boat give separate attention to the bow area.
Excess and unevenly distributed weight in the bow of the boat
can create a water inux hazard, unstable steering conditions,
and even loss of control. Driver visibility can be reduced if the
bow is overloaded or unevenly weighted.
It is the captain’s responsibility to ensure that his/her sight line
is unobstructed
California Proposition 65 Recreational Boats
WARNING: Operating, servicing and maintaining a recreational
marine vessel can expose you to chemicals including engine
exhaust, carbon monoxide, phthalates, and lead, which are
known to the State of California to cause cancer and birth
defects or other reproductive harm. To minimize exposure,
avoid breathing exhaust, service your vessel in a well-ventilated
area and wear gloves or wash your hands frequently when
servicing this vessel. For more information go to www.

Excess and improper loading of bow area forward of windshield
may cause water inux, operating instability, and loss of control
resulting in injury or death. Bow Capacity Limit - Refer to seating
capacities in this manual
Use good judgment when weighting your boat for any towed
water sports. Educate yourself on the proper responses for the
diering and potentially unsafe conditions you could encounter.
Capacity and Weighting Your Boat (continued)
Proper Seating
Proper seating is an important element of boating safety. Proper
seating consists of sitting with your buttocks in full contact with
a seat cushion within easy reach of a suitable handhold or grab
rail anytime the boat is underway. Handholds and grab rails
should be used to secure oneself and prevent loss of balance.
Do not sit in locations not designed as a seat. For instance, do
not sit on seat backs, do not sit on the sides or gunwale of the
boat, and do not sit on the sundeck while the boat is in motion.
See examples below of proper sitting positions.
The driver must be aware of all passenger’s locations and
positions, and passengers must stay alert to changes in
direction.
The boat is capable of quick and tight turns. Such
maneuvers can cause unseated occupants to be thrown
around or out of the boat. Alert passengers before
changes in direction.
Convertible Rear Seat
Some Supra models are equipped with a convertible rear seat.
The rear seat lifts from the back, hinges forward, and can be
used for a cockpit table. Lift the table forward and it becomes
a rear facing seat.
The convertible rear seat back does not lock into place. It is not
intended as support. Do not lean on or use as a brace in case
of sudden change in direction.

Maximum Capacities
In compliance with United States Coast Guard Regulations,
Supra Boats meet or exceed all safety standards designed for
recreational boats. To ensure safe handling and performance,
each Supra boat displays a maximum capacity sticker (see
sample), stating the maximum total weight load allowable.
NOTICE: Refer to the Maximum Capacity Sticker on your
boat for allowable loading.
Do not exceed the maximum capacity of the boat.
Coast Guard Regulations
The United States Coast Guard boating regulations prescribe
minimum standards of safety to be met and maintained by all
watercraft. It is necessary that your boat remain in compliance
with these regulations.
The staff at Skier’s Choice, Inc. recommend that all boat
operators complete a Coast Guard approved boating safety
course.
