Boater’s Responsibilities

The boat driver is responsible for correct and safe operation of the

boat and safety of its occupants and general public. It is strongly rec-

ommended that each operator (driver) read and understand this en-

tire 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

Before Operating Your Outboard

practiced along with using good common sense can help prevent

personal injury and product damage. If you have any questions,

contact your dealer.

This manual as well as safety labels posted on the outboard use

safety alerts to draw your attention to special safety instructions that

must be followed.

WARNING

WARNING – Hazards or unsafe practices which COULD result

in severe personal injury or death.

CAUTION

CAUTION – Hazards or unsafe practices which could result in

minor injury or product or property damage.

Boat Horsepower Capacity

1Do not overpower or overload your boat. Most boats will carry a

required capacity plate indicating the maximum acceptable

power and load as determined by the manufacturer following

certain federal guidelines. If in doubt, contact your dealer or the

boat manufacturer.

WARNING

Overpowering a Boat Can Cause:

•Serious injury, death, or boat damage.

•Loss of Boat Control.

•Flotation Characteristics of Boat to be Altered from Placing

Too Much Weight on Transom.

•Boat to Break Apart, Particularly Around the Transom

Area.

High-Speed And High-Performance Boat

Operation

2If you are not familiar with high-performance boat operation we

recommend that you first request an orientation/demonstration

ride with your dealer or an operator experienced with your boat/

outboard combination. Refer to the “Guide to Hi-Performance

Boat Operation” booklet (Part Number 90-849250) included in

your literature packet.

Lanyard Stop Switch

WARNING

Should the operator fall out of the boat, the possibility of seri-

ous 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

immediately, a boat will continue to coast for some distance de-

pending 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.

ob GENERAL INFORMATION

Lanyard Stop Switch (Continued)

WARNING

Avoid serious injury or death from deceleration forces result-

ing from in accidental stop switch activation. The boat opera-

tor should never leave the operator’s station without first dis-

connecting the stop switch lanyard cord from themself.

Accidental or unintended activation of the Lanyard Stop Switch dur-

ing normal operation is a possibility and 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 cur-

rent or high winds.

3. Loss of control when docking.

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 outboard

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 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.
