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, all of them were designed to insure your safety, and the safety of
other people, vessels and property.
In addition to this Owner’s Manual Supplement, please read the Sport Boat Owner’s Manual and all accessory
instructions for important safety standards and hazard information.
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 the boat’s beauty, greatly affect its performance and may damage the gelcoat.
•Periodically haul the boat out of the water and scrub the hull bottom with a bristle brush and a solution of soap
and water.
FALLING and ROTATING PROPELLER HAZARD!
NEVER allow anyone to ride on parts of the boat not designed for
such use.
•Sitting on seat backs, lounging on the forward deck, bow riding, gunwale riding or occupy-
ing the transom platform while underway is especially hazardous and will cause personal
injury or death.
DANGER!
!
ROTATING PROPELLER and CARBON MONOXIDE
POISONING HAZARD!
•NEVER allow anyone to occupy, or hang from, the
back deck or swim platform while the engine(s)
are running.
•Teak surfing, dragging, or water skiing within 20 feet
of a moving watercraft can be fatal.
DANGER!
!
PERSONAL SAFETY HAZARD!
ALWAYS secure the anchor and other loose objects before getting underway. The anchor and
other items that are not properly secured can come loose when the boat is moving and cause
personal injury or death.
DANGER!
!
•To help seal thehull bottom and reduce the possibilityof gelcoat blistering on moored boats,
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.

Carbon Monoxide (CO)
Facts about CO
•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.

Where and 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 and Others From CO
•Know where and how CO may accumulate in and around your boat (see above).
•Maintain fresh air circulation throughout the boat at all times.
•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) are 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 the 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.
•Install and maintain CO alarms inside your boat. Do not ignore any alarm. Replace alarms as recommended by the
alarm manufacturer.
•Follow the checklists provided on the next page.
•Get a Vessel Safety Check.

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.
❏Confirm that water flows from the exhaust outlet when the engines and generator are started.
❏Listen for any change in exhaust sound, which could indicate an exhaust component failure.
❏Test the operation of each CO alarm 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 Qualified 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).
