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 boat.
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.
Before Operating Your Boat
Read and understand this manual carefully. Learn how to operate
your boat properly. If you have any questions, contact your dealer.
Safety and operating information that is practiced, along with using
good common sense, can help prevent personal injury and product
damage.
This manual uses the following safety alerts to draw your attention
to special safety instructions that should be followed.
! WARNING
WARNING—indicates a potentially hazardous situation that, if
not avoided, could result in death or serious injury.
! DANGER
DANGER—indicates an imminently hazardous situation that, if
not avoided, will result in death or serious injury.
! CAUTION
CAUTION—indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate injury or property
damage. It may also be used to alert against unsafe practices.

GENERAL INFORMATION

Lanyard Stop Switch
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.
The lanyard is a cord usually between
122 and 152 cm (4 and 5 feet) 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 to minimize
the likelihood of lanyard 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.

Read the following Safety Information before proceeding.

GENERAL INFORMATION

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. Falling overboard
and accidental ejections are more likely to occur in certain types
of boats such as low sided inflatables, bass boats, high
performance boats, and light, sensitive handling fishing boats
operated by a hand tiller. Falling overboard and accidental
ejections 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, 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
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.

GENERAL INFORMATION
9
! WARNING
Avoid serious injury or death from deceleration forces resulting
from 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.
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:
• 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 gearcase or propeller.
• Loss of power and directional control in heavy seas, strong
current or high winds.
• Loss of control when docking.
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.
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 (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.

GENERAL INFORMATION
10
WHILE BOAT IS STATIONARY
! 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
gearcase, or any solid device rigidly attached to a moving boat
or gearcase.
Shift outboard into neutral and shut off the engine before allowing
people to swim or be in the water near your boat.
Wave And Wake Jumping
Operating recreational boats over waves and wake is a natural part
of boating. However, when this activity is done with sufficient speed
to force the boat hull partially or completely out of the water, certain
hazards arise, particularly when the boat re‑enters the water.
14463
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
veer violently in a new direction. Such a sharp change in direction
can cause occupants to be thrown out of their seats, or out of the
boat.
! 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
11
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 to a nearly instantaneous stop and can send
the occupants flying forward. The boat may also steer sharply to
one side.
Impact With Underwater Hazards
Reduce speed and proceed with caution whenever you drive a
boat in shallow water areas, or in areas where you suspect
underwater obstacles may exist which could be struck by the
outboard or the boat bottom. The most important thing you can do
to help reduce injury or impact damage from striking a floating or
underwater object is to control the boat speed. Under these
conditions, boat speed should be kept to a minimum planing speed
of 24 to 40 km/h (15 to 25 MPH).
14462
! WARNING
To avoid serious injury or death from all or part of an outboard
coming into the boat after striking a floating or underwater
obstacle maintain a top speed no greater than minimum planing
speed.
Striking a floating or underwater object could result in an infinite
number of situations. Some of these situations could result in the
following:
• Part of the outboard or the entire outboard could break loose
and fly into the boat.

GENERAL INFORMATION
12
• The boat could move suddenly in a new direction. Such a
sharp change in direction 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, or even out of the boat.
• Impact damage to the outboard and/or boat.
Keep in mind, the most important thing you can do to help reduce
injury or impact damage during an impact is control the boat speed.
Boat speed should be kept to a minimum planing speed when
driving in waters known to have underwater obstacles.
After striking a submerged object, stop the engine as soon as
possible and inspect it for any broken or loose parts. If damage is
present or suspected, the outboard 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, or water leaks.
Operating a damaged outboard could cause additional damage to
other parts of the outboard, 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.
Exhaust Emissions
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide is present in the exhaust fumes of all internal
combustion engines. This includes the outboards, sterndrives 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.

GENERAL INFORMATION
13
! 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.
21622
Example of desired air flow through the boat
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 enclosed area of a stationary boat that
contains or is near a running engine may be exposed to a
hazardous level of carbon monoxide.

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.
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. Do not allow
anyone to sit or ride on any part of the boat that was not intended
for such use. This includes the back of seats, gunwales, transom,
bow, decks, raised fishing seats, any rotating fishing seat; or
anywhere that an 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.

GENERAL INFORMATION
15
Never be under the influence of alcohol or drugs while boating (it
is the law). Alcohol or drug use impairs your judgment and greatly
reduces your ability to react quickly.
Prepare other boat operators. Instruct at least one other 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 40 km/h (25 MPH) will
overtake a fallen skier 61 m (200 ft.) in front of you in 5 seconds.
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 assist 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.
