Lanyard Stop Switch
WARNING
Should the operator fall out of the boat, the possibility of serious injury or death from being run over by the boat can be
greatly reduced by stopping the engine immediately. Always
properly connect both ends of the stop switch lanyard to the
stop switch and the operator.
1 The purpose of a lanyard stop switch is to turn off the engine
when the operator moves far enough away from the operator’s
position (as in accidental ejection from the operator’s position) to
activate the switch. A lanyard stop switch can be installed as an
accessory – generally on the dashboard or side adjacent to the
operator’s position.
2 While activation of the lanyard stop switch will stop the engine im-
mediately, a boat will continue to coast for some distance depending upon the velocity and degree of any turn at shut-down.
However, the boat will not complete a full circle. While the boat
is coasting, it can cause injury to anyone in the boat’s path as s eriously as the boat would when under power.

GENERAL INFORMATION
Lanyard Stop Switch (Continued)
WARNING
Avoid serious injury or death from deceleration forces resulting from in accidental stop switch activation. The boat operator should never leave the operator’s station without first disconnecting the stop switch lanyard cord from themself.
Accidental or unintended activation of the Lanyard Stop Switch during normal operation is a possibility and could cause any, or a ll , of t he
following potentially hazardous situations:
3 Occupants could be thrown forward due to 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 gear case or propeller.
4 Loss of power and directional control in heavy seas, strong cur-
rent or high winds.
5 Loss of control when docking.

Trailering Boat
Boat can be trailered with drive unit in “up” or “down” position.
Adequate road clearance is required between road and gear housing
skeg when trailering with drive unit in “down” position.
If adequate road clearance is a problem, place drive unit in full trailer
position and support with an optional trailer kit which is available from
your Authorized MerCruiser Dealer.

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 speed.
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) even with the drive unit
in neutral position, there is sufficient force by the water to rotate the
propeller. This neutral propeller rotation can cause serious injury.
WHILE BOAT IS STATIONARY
Shift the drive unit into neutral and shut off the engine before allowing
people to swim or be in the water near your boat.
WARNING
Stop your engine immediately whenever anyone in the water
is near your boat. Serious injury to the person in the water is
likely if contacted by a rotating propeller, a moving boat, a
moving gear case, or any solid device rigidly attached to a
moving boat or gear case.

GENERAL INFORMATION
Carbon Monoxide Risk
WARNING
Avoid the combination of a running engine and poor ventilation. Prolonged exposure to carbon monoxide in sufficient
concentration can lead to unconsciousness, brain damage, or
death.
Carbon monoxide is a deadly gas that is odorless, colorless and
tasteless and is present in the exhaust fumes of all internal
combustion engines.
Early symptoms of carbon monoxide poisoning which should not be
confused with seasickness or intoxication, include headache, dizziness, drowsiness, and nausea.
INSUFFICIENT FRESH AIR FLOW
Under certain conditions, 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 rare, on a very calm day, swimmers and passengers in an
open stationary boat with a running engine, or near a running engine
may be exposed to a hazardous level of carbon monoxide.
Insufficient Air Flow Could Occur If:
While boat is stationary
1 Boat moored in a confined space with the engine running.
2 Boat is moored close to another boat with its engine running.
While boat is moving
3 Running the boat with the trim angle of the bow too high.
4 Running the boat with no forward hatches open (station wagon
effect).
SUFFICIENT FRESH AIR FLOW
5 Example of desired air flow through the boat.
Ventilate passenger area, open side curtains, or forward hatches to
remove carbon monoxide fumes.

GENERAL INFORMATION
Wave And Wake Jumping
Operating recreational boats over waves and wakes is a natural part
of boating. However, when this activity is done with speed to force the
boat hull partially or completely out of the water, certain hazards
arise, particularly when the boat re-enters the water.
The primary concern is the boat changing direction while in the midst
of the jump. In such case the landing may cause the boat to violently
veer in a new direction. Such a sharp change in direction or turn can
cause occupants to be thrown out of their seats or out of the boat.
There is another less common hazardous result from allowing your
boat to launch off a wave or wake. If the bow of your boat pitches
down far enough while airborne, upon water contact it may penetrate
under the water surface and “submarine” for an instant. This will bring
the boat nearly to a stop in an instant and can send the occupants
flying forward. The boat may also steer sharply to one side.
WARNING
Avoid serious injury or death from being thrown within or out
of a boat when it lands after jumping a wave or wake. Avoid
wave or wake jumping whenever possible. Instruct all occupants that if a wake or wave jump occurs, get low and hang on
to any boat hand hold.

GENERAL INFORMATION
Impact With Underwater Hazards
Reduce speed and proceed with caution whenever you’re driving a
boat in shallow water areas or in areas where the waters are suspected of having underwater obstacles that could be struck by the
sterndrive or the boat bottom. The Power Trim hydraulic system is
designed to provide some impact protection for the drive unit if a submerged object is struck while boat is moving forward. There is no impact protection in REVERSE. The hydraulic system will cushion the
kickup of the drive unit as it clears the object, reducing damage to
unit. After drive unit has cleared object, the drive will return to the
original operating position, preventing loss of steering control and
engine over-speed. The most important thing you can do to help
reduce injury or impact damage from striking a floating or
underwater object is control the boat speed. When driving in
waters known to have floating or underwater obstacles, boat
speed should be kept to a minimum planing speed (15 to 25
mph).
IMPORTANT: The impact protection system cannot be
designed to ensure total protection from impact damage under
all conditions.

GENERAL INFORMATION
Impact With Underwater Hazards (cont.)
Striking a floating/underwater object may result in an infinite number
of situations. Some of these situations could result in the following:
• The boat could move suddenly in a new direction. Such a sharp
change in direction or turn can cause occupants to be thrown out
of their seats or out of the boat.
• A rapid reduction in speed. This will cause occupants to be thrown
forward, even out of the boat.
• Impact damage to the sterndrive and/or boat.
After striking a submerged object, stop engine as soon as possible
and inspect the sterndrive unit for any broken or loose parts. If damage is present or suspected, the power package should be taken to
an authorized dealer for a thorough inspection and necessary repair.
The boat should also be checked for any hull fractures, transom fractures, water leaks.
Operating a damaged sterndrive could cause additional damage to
other parts of the power package, or could affect control of the boat.
If continued running is necessary, do so at greatly reduced speeds.
WARNING
Avoid serious injury or death from loss of boat control. Continued boating with major impact damage can result in sudden
component failure with or without subsequent impacts, Have
the power package thoroughly inspected and any necessary
repairs made.
