WARNING

If the operator falls out of the boat, stop the engine immediately to reduce the possibility of serious injury or death from being

struck by the boat. Always properly connect the operator to the stop switch using a lanyard.

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 propulsion or steering components.

•

Loss of power and directional control in heavy seas, strong current, or high winds.

•

Loss of control when docking.

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.

Keep the Lanyard Stop Switch and Lanyard Cord in Good Operating Condition

Before each use, ensure that the lanyard stop switch works properly. Start the engine, and then stop it by pulling the lanyard

cord. If the engine does not stop, have the switch repaired before operating the boat.
Before each use, inspect the lanyard cord to ensure that it is in good working condition and that there are no breaks, cuts, or

wear to the cord. Check that the clips on the ends of the cord are in good condition. Replace any damaged or worn lanyard

cords.

Emergency Stop Switch

An emergency stop (E‑stop) switch is used to turn off the engines in an emergency situation, such as a person overboard or a

tangled propeller. When activated, an E‑stop switch interrupts the power supply to the engine and transmission. If the boat is

equipped with an E‑stop switch, the E‑stop switch turns off all of the engines.

Typical E-stop switch

Activation of an E‑stop switch stops the engines immediately, but the boat can continue to coast for some distance depending

upon the velocity and degree of any turn at shutdown. 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.
Always instruct other occupants on proper starting and operating procedures should they need to operate the engine in an

emergency.
It is possible to accidentally or unintentionally activate the switch during normal operation. This can cause any or all of the

following potentially hazardous situations:
•

Passengers can be thrown forward due to the unexpected loss of forward motion, and passengers in the front of the boat

could be ejected over the bow and possibly struck by the propulsion or steering components.

•

The operator can lose power and directional control in heavy seas, strong current, or high winds.

•

The operator can lose control of the vessel when docking.

Restarting an engine using the key switch or start button after an E‑stop shutdown without first turning the key switch to the off

position for at least 30 seconds will restart the engine but cause fault codes to be set. Unless you are in a potentially hazardous

situation, turn the key switch off and wait at least 30 seconds before restarting the engine or engines. If after restarting, some

fault codes are still being displayed, contact your authorized Mercury Diesel repair facility.
