Outside the United States, your selling dealer, national sailing federation, or local boat club can advise you of local
sea schools or competent instructors.
Special Care for Moored Boats
•Whether moored in saltwater or freshwater, your boat will collect marine growth on its hull bottom.
•This will detract from your boat’s beauty, greatly affect its performance, and may damage the gel coat.
•Periodically haul your boat out of the water and scrub the hull bottom with a bristle brush and a solution of soap
and water.
Structural Limitations
The swim platform extension is designed to be lightweight for proper boat balance. The load limit for the swim plat-
form extension is 30 pounds per square foot, evenly distributed.
CONTROL HAZARD!
An experienced operator MUST be in control of your boat at ALL times. Do NOT operate your
boat while under the influence of alcohol or drugs.
WARNING!
!
•To help seal the hull bottom and reduce the chance of gel coat blistering while your boat is
moored, apply an epoxy barrier coating.
•The barrier coating should be covered with several coats of anti-fouling paint.
•Many states regulate the chemical content of bottom paints in order to meet environmental
standards. Check with your local dealer about recommended bottom paints, and about the
laws in effect in your area.
NOTICE

Chapter 1: Welcome Aboard!

Safety Standards
•Your boat’s mechanical and electrical systems were designed to meet safety standards in effect at the time it
was built.
•Some of these standards were mandated by law, and all of them were designed to insure your safety and the safety
of other people, vessels and property.
Read this supplement, the Sport Boat Owner’s Manual, and all accessory instructions for important safety standards
and hazard information.
FALLING and ROTATING PROPELLER HAZARD!
•NEVER allow anyone to ride on parts of your boat NOT designed for
such use.
•Sitting on seat-backs, lounging on the forward deck, bow riding, gun-
wale riding or occupying the transom platform while underway is especially hazardous and
WILL cause personal injury or death.

Carbon Monoxide (CO)
CO Facts
•CO poisoning causes a significant number of boating deaths each year.
•Called the "silent killer", CO is an extremely toxic, colorless, odorless and tasteless gas.
•CO can harm or even kill you inside or outside your boat.
•CO can affect you whether you’re underway, moored, or anchored.
•CO symptoms are similar to seasickness or alcohol intoxication.
•CO can make you sick in seconds. In high enough concentrations, even a few breaths can be fatal.
•Breathing CO blocks the ability of your blood to carry oxygen.
•The effects are cumulative. Even low levels of exposure can result in injury or death.
Factors that Increase the Effects of CO Poisoning
•Age
•Smokers or people exposed to high concentrations of cigarette smoke
•Consumption of alcohol
•Lung disorders
•Heart problems
•Pregnancy
•Carbon monoxide gas (CO) is colorless, odorless, tasteless, and
extremely dangerous.
•ALL engines, generators, and fuel burning appliances produce CO
as exhaust.
•Prolonged exposure to low concentrations or very quick exposure to high
concentrations WILL cause BRAIN DAMAGE or DEATH.
•Teak surfing, dragging, or water skiing within 20 feet of a moving water-
craft can be fatal.
DANGER!

Where & How CO Can Accumulate
Stationary conditions that increase CO accumulations include:
To correct stationary situations A and/or B:
•Close all windows, portlights and hatches.
•If possible, move your boat away from source of CO.
Running conditions that increase CO accumulations include:
To correct running situations C and/or D:
•Trim bow down.
•Open windows and canvas.
•When possible, run boat so that prevailing winds help dissipate exhaust.
How to Protect Yourself & Others From CO
•Know where and how CO may accumulate in and around your boat (see above).
•Always maintain fresh air circulation throughout your boat.
•Know where your engine and generator exhaust outlets are located and keep everyone away from these areas.
•Never sit on, or hang onto, the back deck or swim platform while the engine(s) is running.
•Never enter the areas under swim platforms where exhaust outlets are located.
•Although CO can be present without the smell of exhaust fumes, if exhaust fumes are detected on your boat, take
immediate action to dissipate these fumes.
•Treat symptoms of seasickness as possible CO poisoning. Get the person into fresh air immediately. Seek medical
attention—unless you’re sure it’s not CO.
•Maintain the CO monitors inside your boat. Never ignore any alarm. Replace monitors as recommended by the
monitor manufacturer.
•Follow the checklists provided on the next page.
•Get a Vessel Safety Check.
For information on how to get a free VESSEL SAFETY CHECK, visit www.vesselsafetycheck.org or contact your

CO Checklists
Trip Checklist
❏Make sure you know where the exhaust outlets are located on your boat.
❏Educate all passengers about the symptoms of CO poisoning and where CO may accumulate.
❏When docked, or rafted with another boat, be aware of exhaust emissions from the other boat.
❏Listen for any change in exhaust sound, which could mean an exhaust component failure.
❏Test the operation of each CO monitor by pressing the test button.
Monthly Checklist
❏Make sure all exhaust clamps are in place and secure.
❏Look for exhaust leaking from exhaust system components. Signs include rust and/or black streaking, water
leaks, or corroded or cracked fittings.
❏Inspect rubber exhaust hoses for burned, cracked, or deteriorated sections. All rubber hoses should be pliable and
free of kinks.
Annual Checklist
Have a Trained Marine Technician:
❏Replace exhaust hoses if cracking, charring, or deterioration is found.
❏Ensure that your engines and generators are properly tuned, and well maintained.
❏Inspect each water pump impeller and the water pump housing. Replace if worn. Make sure cooling systems are
in working condition.
❏Inspect all metallic exhaust components for cracking, rusting, leaking, or loosening. Make sure they check the
cylinder head gasket, exhaust manifold, water injection elbow, and the threaded adapter nipple between the man-
ifold and the elbow.
❏Clean, inspect, and confirm proper operation of the generator cooling water anti-siphon valve (if equipped).
CO Monitor
•Do not disconnect the CO monitor.
•Read the manufacturer’s instructions for your CO monitor. If you did not get the manufacturer’s instructions,
call [phone] and they will be mailed to you.
If your boat is not equipped with a CO monitor, consider purchasing one from your dealer or marine supply store.
The stereo memory and CO monitor place a small, but constant drain on the battery.
