GENERAL INFORMATION

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

Read this manual carefully. Safety and operating information that is

practiced along with using good common sense can help prevent

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

tact 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 pow-

er 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 included in your literature packet.

GENERAL INFORMATION

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.

1The 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.

2While activation of the lanyard stop switch will stop the engine im-

mediately, 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 se-

riously as the boat would when under power.
