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.
Sacrificial Anodes (Zincs)
Your boat is equipped with sacrificial anodes (zincs) to protect underwater metal parts from excessive deterioration.
Check the zincs regularly and replace them if they have deteriorated more than 70%.
There are many factors that affect the rate at which the zincs deteriorate, including:
•Water temperature.
•Salinity.
•Water pollution.
•Stray electrical current from the boat or dock may cause complete deterioration in just a few weeks.
•If there is rapid zinc deterioration, measure the electrolytic corrosion around your boat with a Corrosion
Test Meter.
•To help seal thehull bottom and reduce the possibility of 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.
NOTICE
•Do not paint between the zinc and the metal surface it contacts and do not paint over
the zincs.
•If the zincs are not bonded correctly, they will not provide protection.

Boat Lifting
•Always follow the lift equipment’s instructions and requirements.
•Water in the bilge can shift and change the balance of the load.
•If water is present in the bilge, pump or drain the water out of the bilge areas before lifting your boat.
•When lifting your boat, always position the lifting slings at the port and starboard lifting sling label positions as
shown in the illustration.
PERSONAL INJURY and /or PRODUCT OR PROPERTY DAMAGE HAZARD!
•Lifting slings may slip on the hull.
•Avoid serious injury or death by securing the lifting slings together before lifting.
WARNING!
!
PERSONAL INJURY and /or PRODUCT OR PROPERTY DAMAGE HAZARD!
•NEVER lift any boat using the cleats, or the bow and stern eyes.

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
watercraft can be fatal.
DANGER!

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.
For information on how to get a free VESSEL SAFETY CHECK, visit www.vesselsafetycheck.org or contact your
local U.S. Coast Guard Auxiliary or United States Power Squadrons®.
•U.S. Coast Guard Auxiliary: 1-800-368-5647 or on the Internet at: http://www.cgaux.org
•U.S. Power Squadrons: 1-888-FOR-USPS (1-888-367-8777) or on the Internet at: http://www.usps.org
A. Using engine, generator, or other fuel burn-
ing device when boat is moored in a con-
fined space.
B. Mooring too close to another boat that is
using its engine, generator, or other fuel
burning device.
C. Running boat with trim angle of bow too high. D. Running boat without through ventilation
(station wagon effect).

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 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
manifold and the elbow.
❏Clean, inspect, and confirm proper operation of the generator cooling water anti-siphon valve (if equipped).
Carbon Monoxide Alarm System
•Do not disconnect the alarm system.
•Read the manufacturer’s instructions for your CO alarm system. If you did not receive an instruction manual, call
[phone] and one will be mailed to you.
If your boat is not equipped with a carbon monoxide alarm, consider purchasing one from your dealer or marine
supply store.
•The stereo memory and CO monitor(s) place a small, but constant drain on the battery.
•If your boat will be unattended for an extended amount of time, plug into shore power with
the battery charger turned On.
