Features And Controls
Emergency Stop Switch, If Equipped
An emergency stop (E‑stop) switch turns 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 at the helm, the E‑stop switch turns off all of the engines.
Activation of an E‑stop switch stops the engine, or 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.
We recommend instructing other occupants on proper starting and operating procedures should they need to operate the engine
in an emergency.
Accidental or unintended activation of the switch during normal operation is also possible, which can cause any or all of the following
potentially hazardous situations:
•
Occupants can be thrown forward due to 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 Cummins MerCruiser Diesel Repair Facility.
