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.
