CALIFORNIA-SPECIFIC INFORMATION
Boats manufactured for use in California for model year 2018 and after
meet the California EVAP Emissions regulation for spark-ignition marine
watercraft. Boats meeting this requirement will have the following label
affixed near thehelm.
The fuel system in boats marketed in states other than California complies
with U.S. EPA-mandated evaporative emission standards at time of
manufacture using certified components.
CALIFORNIA AIR RESOURCES BOARD (CARB)
Outboard, sterndrive and inboard powered boats sold in the state of
California are equipped with special components and certified to meet
stricter environmental standards and exhaust emissions. All boats sold in
California since 2009 are required to meet Super-Ultra-Low (four-star)
emissions.
EXHAUST EMISSIONS
Sterndrive and inboard marine engine powered boats
meeting CARB’s exhaust emission standards are
required to display the four-star label on the outside
of the hull above the waterline. Outboard and
personal watercraft marine engines may also comply
with these standards.
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.P65warnings.ca.gov/marine
Carbon monoxide (CO) can cause brain damage or death. Engine and
generator exhaust contains odorless and colorless carbon monoxide
gas. Carbon monoxide will be around the back of the boat when
engines or generators are running. Signs of carbon monoxide
poisoning include nausea, headache, dizziness, drowsiness and lack
of consciousness. Get fresh air if anyone shows signs of carbon
monoxide poisoning. See engine manufacturer’s manual for
information regarding carbon monoxide poisoning.

CARBONMONOXIDEGAS
!DANGER
Carbon monoxide gas (CO) is colorless, odorless
and extremely dangerous. All engines and fuel
burning appliances produce CO as exhaust.
Direct and prolonged exposure to CO will cause
BRAIN DAMAGE or DEATH. Signs of exposure to
CO include nausea, dizziness and drowsiness.
Ensure adequate ventilation to prevent
accumulation of CO in the boat.
Each year, boaters are injured or killed by carbon monoxide.
Virtually all of these injuries and deaths are preventable. Carbon
monoxide is a potentially deadly gas produced anytime a carbon-
based fuel, such as gasoline, burns. Carbon monoxide sources
on your boat include gasoline engines and generators, cooking
ranges, space heaters and water heaters.
Do not confuse carbon monoxide poisoning with seasickness,
intoxication or heat stress. If someone complains of irritated
eyes, headache, nausea, weakness, dizziness or drowsiness,
or you suspect carbon monoxide poisoning, immediately move
the person to fresh air, investigate the cause and take corrective
action. Seek medical attention if necessary.
Indmar engines are equipped with catalytic converters which
significantly reduce harmful CO emissions, but it is important that
all of the DO’s and DON’Ts still be followed.
Please follow these DOs and DON’Ts to ensure a safe boating
experience every time.
DON’T swim or sit near the swim platform when any engine is
running.
DON’T hold on to the swim platform while the boat is underway
(no “Teak Surfing”).
DON’T moor next to another boat whose engine is running.
DON’T confuse carbon monoxide poisoning with seasickness or
intoxication.

SAFETY
© 2020 Indmar Marine Engines
DO immediately move the person to fresh air, investigate the
cause and take corrective action if someone on board complains
of irritated eyes, headache, nausea, weakness or dizziness. Seek
medical attention if necessary.
DO make sure generators are properly ventilated and keep engine
and generator exhausts clear.
DO always shut off engine and generator when moored, anchored
or standing still.
DO be aware that the station wagon effect, or backdrafting, can
cause carbon monoxide to accumulate inside the cabin, cockpit
and bilge when the boat is underway, moving at slow speed or
idling.
DO keep your boat’s engine well-maintained and regularly check
to make sure carbon monoxide detectors in the cabin are working
properly.
DO always wear a properly fitted life jacket while in or around
water.
For more information on carbon monoxide and boats, contact the
US Coast Guard Office of Boating Safety at 1-800-368-5647 or
www.uscgboating.org or your state boating law administrator at
1-800-225-9487 or www.nasbla.org.

FUEL
!DANGER
Gasoline (petrol) is extremely flammable and
highly explosive under certain conditions.
Explosive gasoline fumes may accumulate in
the engine compartment. Failure to properly
ventilate fumes with the bilge blower may result
in explosive atmosphere.
Indmar marine engines use gasoline (petrol) for fuel. The area
under the engine and around the gasoline tank and supply lines
is not open to outside air. Ventilation around these areas must be
provided by your bilge blower system and air vents located around
the boat. We recommend taking time out to carefully inspect your
boat at least once a day for gasoline fumes, oil leaks, and areas
where wiring may be worn or damaged.
!WARNING
Always operate the bilge blower at least 4
minutes prior to starting the engine. Raise the
engine cover to ventilate fumes. Inspect the
engine and compartment for any fluid or fuel
leaks.
x Do not smoke or allow open flames or sparks nearby when
refueling.
x Always stop the engine before refueling.
x Maintain contact between the fuel nozzle and the fuel tank or
container to prevent electrostatic spark. Do not use a plastic
funnel.
x Do not block fuel vents.
x Do not store fuel in any containers or compartments which are
not designated for fuel storage and do not use these storage
areas for any other purpose.
