warranty registration information regarding recreational use, or
subsequent change of use from recreational to commercial may void
the warranty at the sole discretion of Mercury Marine. Routine
maintenance outlined in the Operation and Maintenance Manual must
be timely performed in order to maintain warranty coverage. Mercury
Marine reserves the right to make warranty coverage contingent upon
proof of proper maintenance.
WHAT MERCURY WILL DO

A decal near the lanyard stop switch is a visual reminder for the
operator to attach the lanyard to his or her personal flotation device
(PFD) or wrist.

Accidental ejections, such as falling overboard, are more likely to
occur in:
• Low‑sided sport boats
• Bass boats
• High‑performance boats
Accidental ejections are also likely to result from poor operating
practices, such as:
• Sitting on the back of the seat or on the gunwale at planing
speeds
• Standing at planing speeds
• Operating at planing speeds in shallow waters or where there
are many obstacles
• Releasing your grip on the steering wheel that is pulling in one
direction

RUN
ATTACH LANYARD
• Operating the boat after consuming alcohol or drugs
• Performing high‑speed boating maneuvers
The lanyard cord is usually 122–152 cm (48–60 in.) long when
stretched out. It has an element on one end made to be inserted into
the switch and a clip on the other end for attaching to the operator's
PFD or wrist. The lanyard is coiled to make its at‑rest condition as
short as possible to minimize the likelihood of entanglement with
nearby objects. Its stretched‑out length is made to minimize the
likelihood of accidental activation should the operator choose to move
around in an area close to the normal operator's position. If it is
desired to have a shorter lanyard, wrap the lanyard around the
operator's wrist or leg, or tie a knot in the lanyard.
Activation of the lanyard stop switch will stop the engine immediately,
but the boat will continue to coast for some distance, depending upon
the velocity and degree of any turn at shutdown. While the boat is
coasting, it can cause injury to anyone in the boat's path as seriously
as the boat would when under power.
Always instruct other occupants on proper starting and operating
procedures should they be required to operate the engine in an
emergency (if the operator is accidentally ejected).
! WARNING
Avoid serious injury or death resulting from being struck by an
uncontrolled boat. Failure to use the lanyard safety device
substantially increases the risk of being struck by an uncontrolled
boat should you, as operator, be ejected. As operator, always use
the lanyard stop switch, which will automatically disable the engines
in the case of ejection or being thrown from the operator position.
Accidental or unintended activation of the switch during normal
operation is also a possibility. This could cause any, or all, of the
following potentially hazardous situations:

2 - GENERAL INFORMATION
14 90-8M0114812 JANUARY 2016
• Occupants thrown forward due to the unexpected loss of
forward motion ‑ a particular concern for passengers in the front
of the boat who could be ejected over the bow and possibly
struck by the propulsion or steering components.
• Loss of power and directional control in heavy seas, strong
current, or high winds.
• Loss of control when docking.
! WARNING
Avoid serious injury or death from sudden deceleration forces
resulting from accidental or unintended switch activation. The
lanyard switch is designed to quickly stop the boat when activated.
Be cautious of accidental lanyard switch activation.
TRAILERING THE BOAT
The boat can be trailered with the drive unit in up or down position.
Adequate road clearance is required between road and gear housing
skeg when trailering with the drive unit in down position.
If adequate road clearance is a problem, place drive unit in full up
position.
PROTECTING PEOPLE IN THE WATER
WHILE YOU ARE CRUISING
It is very difficult for a person in the water to take quick action to avoid
a boat heading in their direction, even at slow speeds.
21604
Always slow down and exercise extreme caution any time you are
boating in an area where there might be people in the water.
Whenever a boat is moving (even coasting) and the gear shift is in
neutral, there is sufficient force by the water on the propeller to cause
the propeller to rotate. This neutral propeller rotation can cause
serious injury.
WHILE BOAT IS STATIONARY
! WARNING
A spinning propeller, a moving boat, or any solid device attached to
the boat can cause serious injury or death to swimmers. Stop the
engine immediately whenever anyone in the water is near your
boat.
Shift into neutral and shut off the engine before allowing people to
swim or be in the water near your boat.

EXHAUST EMISSIONS
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide (CO) is a deadly gas that is present in the exhaust
fumes of all internal combustion engines, including the engines that
propel boats, and the generators that power boat accessories. By
itself, CO is odorless, colorless, and tasteless, but if you can smell or
taste engine exhaust, you are inhaling CO.
Early symptoms of carbon monoxide poisoning, which are similar to
the symptoms of seasickness and intoxication, include headache,
dizziness, drowsiness, and nausea.
! WARNING
Inhaling engine exhaust gases can result in carbon monoxide
poisoning, which can lead to unconsciousness, brain damage, or
death. Avoid exposure to carbon monoxide.
Stay clear from exhaust areas when engine is running. Keep the
boat well‑ventilated while at rest or underway.
STAY CLEAR OF EXHAUST AREAS
41127
Engine exhaust gases contain harmful carbon monoxide. Avoid areas
of concentrated engine exhaust gases. When engines are running,
keep swimmers away from the boat, and do not sit, lie, or stand on
swim platforms or boarding ladders. While underway, do not allow
passengers to be positioned immediately behind the boat (platform
dragging, teak/body surfing). This dangerous practice not only places
a person in an area of high engine exhaust concentration, but also
subjects them to the possibility of injury from the boat propeller.
GOOD VENTILATION
Ventilate the passenger area, open side curtains or forward hatches
to remove fumes.
Example of desired air flow through the boat:
21622
POOR VENTILATION
Under certain running and/or wind conditions, permanently enclosed
or canvas enclosed cabins or cockpits with insufficient ventilation may
draw in carbon monoxide. Install one or more carbon monoxide
detectors in your boat.
Although the occurrence is rare, on a very calm day, swimmers and
passengers in an open area of a stationary boat that contains, or is
near, a running engine may be exposed to a hazardous level of
carbon monoxide.
