Stopping The Engine; Throttle Only Operation - MerCruiser Sterndrive 4.3 MPI User Manual

Shifting the drive system at RPMs greater than engine idle speed may cause internal
damage to the drive system. Shift the drive system only when the engine is at idle RPM.

STOPPING THE ENGINE

1. Move the remote control handle to neutral/idle and allow the engine to slow to idle
speed. If engine has been operated at high speed for a long period of time, allow the
engine to cool at idle speed for 3 to 5 minutes.
2. The engine can be stopped by any one of the following 4 methods:
a.
b.
c.
d.

Throttle Only Operation

NOTE: When operating in throttle only (neutral) mode, the DTS Control System will not
allow the engine speed to increase above 3500 RPM.
Zero effort remote controls: Zero effort remote controls have seperate throttle control
and shift control levers. Advancing the throttle control lever beyond the idle position while
the shift control lever is in the neutral position will cause engine speed to increase, but only
up to the maximum neutral engine speed of 3500 RPM.
The Digital Throttle and Shift (DTS) Zero Effort control can shift the engine or
transmission at speeds greater than idle, causing unexpected boat movement, which
may result in injury, death, or property damage due to loss of boat control. Always place
the throttle control lever in the idle position before moving the shift control lever into
forward or reverse gear position.
Panel Mount and Console Mount Remote Controls: Panel mount and console mount
remote controls are equipped with a throttle only button. To activate throttle only mode:
1. Refer to Remote Controls section for remote control features.
2. Move the control lever to the idle/neutral position.
3. Depress the throttle only button, and move the control lever to the idle/forward or idle/
reverse position. The DTS control system will sound two beeps on the audio warning
horn to indicate throttle only mode is active. On console mount remote controls, the
neutral light will begin to blink.
4. Advancing the control lever beyond the idle/forward or idle/reverse position will cause
engine speed to increase.
IMPORTANT: Moving the control lever back to the idle/neutral position will deactivate the
throttle only mode and allow the engine to shift into gear.

Move the ignition key switch to the "ACCESSORY" or "OFF" position. The engine
will stop and the control system will be deactivated.
Depress the start/stop button, if equipped. The engine will stop and the control
system will remain active.
Momentarily move the ignition key switch to the "START" position, then release
immediately. The control system will recognize that the engine is running and will
stop the engine. The control system will remain active. Moving the ignition key
switch to the "START" position again will issue a start request to the control system
and the control system will start the engine, if appropriate.
Activate the lanyard stop switch, if equipped. The engine will stop, but the control
system will remain active. The control system will not allow the engine to start if
the lanyard stop switch is activated.
