Boater’s Responsibilities
The operator (driver) is responsible for the correct and safe operation
of the boat and safety of its occupants and general public. It is strongly recommended that each operator (driver) read and understand
this entire manual before operating the outboard.
Be sure at least one additional person on board is instructed in the
basics of starting and operating the outboard and boat handling in
case the driver is unable to operate the boat.
obb1

Do not overpower or overload your boat. Most boats will carry a
required capacity plate indicating the maximum acceptable pow-
er and load as determined by the manufacturer following certain
federal guidelines. If in doubt, contact your dealer or the boat
manufacturer.
WARNING
!
Using an outboard that exceeds the maximum horsepower
limit of a boat can: 1. cause loss of boat control 2. place too
much weight at the transom altering the designed flotation
characteristics of the boat or 3. cause the boat to break apart
particularly around the transom area. Overpowering a boat
can result in serious injury, death, or boat damage.

High-Speed And High-Performance Boat
Operation
2
If your outboard is to be used on a high-speed or high-performance boat with which you are unfamiliar, we recommend that
you never operate it at its high speed capability without first requesting an initial orientation and familiarization demonstration
ride with your dealer or an operator experienced with your boat/
outboard combination. For additional information, read the
“Guide to Hi-Performance Boat Operation” booklet included in
your literature package.

Outboard Remote Control
1 The remote control connected to your outboard must be
equipped with a start-in-gear protection device. This prevents the
engine from starting when the outboard is in gear.
WARNING
!
Avoid serious injury or death from a sudden unexpected acceleration when starting your engine. The design of this outboard requires that the remote control used with it must have
a built in start-in-gear protection device.
obf1
Remote Steering Notice
2 The steering link rod that connects the steering cable to the en-
gine must be fastened utilizing self-locking nuts (a). These selflocking nuts must never be replaced with common nuts (non
locking) as they will work loose and vibrate of f, freeing the link rod
to disengage.
WARNING
!
Disengagement of a steering link rod can result in the boat taking a full, sudden, sharp turn. This potentially violent action
can cause occupants to be thrown overboard exposing them
to serious injury or death.

Lanyard Stop Switch
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. Tiller handle outboards and some remote
control units are equipped with a lanyard stop switch. A lanyard
stop switch can be installed as an accessory – generally on the
dashboard or side adjacent to the operator’s position.
2 The lanyard is a cord usually between 4 and 5 feet (1220 and
1524 mm) in length when stretched out with an element on one
end made to be inserted into the switch and a snap on the other
end for attaching to the operator. The lanyard is coiled to make
its at-rest condition as short as possible so as to minimize the likelihood of lanyard entanglement with nearby objects. It is made
as long as it is in its stretched condition 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.
Read the following Safety Information before proceeding.

GENERAL INFORMATION
Lanyard Stop Switch (Continued)
Read the following Safety Information before proceeding.
Important Safety Information: The purpose of a lanyard stop
switch is to stop the engine when the operator moves far enough
away from the operator’s position to activate the switch. This would
occur if the operator accidentally falls overboard or moves within the
boat a sufficient distance from the operator’s position. Accidental
ejections and falls overboard are more likely to occur in certain types
of boats such as low sided inflatables or bass boats, high-performance boats and light, sensitive-handling fishing boats operated by
hand-tiller. Accidental ejections and falls overboard are also likely to
occur as a result of poor operating practices such as sitting on the
back of the seat or gunwale at planing speeds, standing at planing
speeds, sitting on elevated fishing boat decks, operating at planing
speeds in shallow or obstacle-infested waters, releasing your grip on
a steering wheel or tiller handle that is pulling in one direction, drinking alcohol or consuming drugs, or daring, high-speed boat maneuvers.
While activation of the lanyard stop switch will stop the engine immediately, a boat will continue to coast for some distance depending
upon the velocity and degree of any turn at shut-down. However , t he
boat will not complete a full circle. 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.
We strongly recommend that other occupants be instructed on proper starting and operating procedures should they be required to operate the engine in an emergency (e.g. if the operator is accidentally
ejected).
!
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.
(continued on next page)

GENERAL INFORMATION
Lanyard Stop Switch (Continued)
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:
1. 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.
2. Loss of power and directional control in heavy seas, strong current or high winds.
3. Loss of control when docking.
!
WARNING
Avoid serious injury or death from deceleration forces resulting from in accidental or unintended stop switch activation. The boat operator should never leave the operator’s station without first disconnecting the stop switch
lanyard from the operator.

GENERAL INFORMATION
Protecting People In The Water
WHILE YOU ARE CRUISING
It is very difficult for a person standing or floating in the water to take
quick action to avoid a boat heading in his/her 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 (coasting) and the outboard gear shift is
in neutral position, 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
Shift outboard 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.

Exhaust Emissions
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide is present in the exhaust fumes of all internal combustion engines including the outboards, stern drives and inboard
engines that propel boats, as well as the generators that power various boat accessories. Carbon monoxide is a deadly gas that is odorless, colorless and tasteless.
Early symptoms of carbon monoxide poisoning which should not be
confused with seasickness or intoxication, include headache, dizziness, drowsiness, and nausea.
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.
GOOD VENTILATION
Ventilate passenger area, open side curtains, or forward hatches to
remove fumes.
1 Example of desired air flow through the boat.

Exhaust Emissions (Continued)
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 unclosed area of a stationary boat that contains or
is near a running engine may be exposed to a hazardous level of carbon monoxide.
2 Examples of Poor Ventilation:
While boat is stationary
a. Running the engine when the boat is moored in a confined
space.
b. Mooring close to another boat that has its engine running.
While boat is moving
c. Running the boat with the trim angle of the bow too high.
d. Running the boat with no forward hatches open (station wag-
on effect).

GENERAL INFORMATION
Selecting Accessories For Your Outboard
Genuine Mercury Marine Quicksilver Accessories have been specifically designed and tested for your outboard.
Mercury Marine Quicksilver accessories are available from Mercury
Marine dealers.
Some accessories not manufactured or sold by Mercury Marine are
not designed to be safely used with your outboard or outboard operating system. Acquire and read the installation, operation, and maintenance manuals for all your selected accessories.
WARNING
!
Check with your dealer before installation of accessories. The
misuse of acceptable accessories or the use of unacceptable
accessories can result in serious injury, death, or product failure.

Safe Boating Suggestions
In order to safely enjoy the waterways, familiarize yourself with local
and other governmental boating regulations and restrictions, and
consider the following suggestions.
Use flotation devices. Have an approved personal flotation device
of suitable size for each person aboard (it is the law) and have it
readily accessible.
Do not overload your boat. Most boats are rated and certified for
maximum load (weight) capacities (refer to your boat capacity plate).
If in doubt, contact your dealer or the boats manufacturer.
Perform safety checks and required maintenance. Follow a regular schedule and ensure that all repairs are properly made.

ob
GENERAL INFORMATION
Safe Boating Suggestions (Continued)
Know and obey all nautical rules and laws of the waterways.
Boat operators should complete a boating safety course. Courses
are offered in the U.S.A. by (1) The U.S. Coast Guard Auxiliary, (2)
The Power Squadron, (3) The Red Cross and (4) your state boating
law enforcement agency . Inquiries may be made to the Boating Hotline, 1-800-368-5647 or the Boat U.S. Foundation information number 1-800-336-BOAT.
Make sure everyone in the boat is properly seated. Don’t allow
anyone to sit or ride on any part of the boat that was not intended for
such use. This includes backs of seats, gunwales, transom, bow,
decks, raised fishing seats, any rotating fishing seat; anywhere that
sudden unexpected acceleration, sudden stopping, unexpected loss
of boat control or sudden boat movement could cause a person to be
thrown overboard or into the boat.
Never be under the influence of alcohol or drugs while boating
(it is the law). They impair your judgment and greatly reduce your
ability to react quickly.
Prepare other boat operators. Instruct at least one person on board
in the basics of starting and operating the outboard and boat handling
in case the driver becomes disabled or falls overboard.
Passenger boarding. Stop the engine whenever passengers are
boarding, unloading or are near the back (stern) of the boat. Just
shifting the outboard into neutral is not sufficient.
Be alert. The operator of the boat is responsible by law to “maintain
a proper lookout by sight (and hearing).” The operator must have an
unobstructed view particularly to the front. No passengers, load, or
fishing seats should block the operators view when operating the
boat above idle speed.
Never drive your boat directly behind a water skier in case the
skier falls. As an example, your boat traveling at 25 miles per hour
(40 km/hr) in 5 seconds will overtake a fallen skier who was 200 feet
(61m) in front of you.
(continued on next page)
15
ob
GENERAL INFORMATION
Safe Boating Suggestions (Continued)
Watch fallen skiers. When using your boat for water skiing or similar
activities, always keep a fallen or down skier on the operator’s side
of the boat while returning to attend the skier. The operator should
always have the down skier in sight and never back up to the skier
or anyone in the water.
Report accidents. Boat operators are required by law to file a Boating Accident Report with their state boating law enforcement agency
when their boat is involved in certain boating accidents. A boating accident must be reported if (1) there is loss of life or probable loss of
life, (2) there is personal injury requiring medical treatment beyond
first aid, (3) there is damage to boats or other property where the
damage value exceeds $500.00 or (4) there is complete loss of the
boat. Seek further assistance from local law enforcement.
