Center engine throttle and shift
= neutral/idle unless both control
handles are in the same gear
Turning off one of the outer engines while underway will cause the center
engine to go into forced neutral/idle. Operation to the center engine can be
restored by moving the control handle of the functioning outer engine back into
neutral position and then engaging. The center engine speed and gear shift will
then be controlled by the functioning outer engine.
Turning off the center engine while underway will have no effect on the
operation of the outer engines.
If a failure should occur while underway which causes one of the outer engines
into forced neutral/idle condition, the center engine will also be forced to
neutral/idle. Operation to the center engine can be restored by moving the
control handle of the functioning outer engine back into neutral and then
engaging.
QUAD-ENGINE THROTTLE AND SHIFT OPERATION
Movement of the handles on the remote control allows the boat operator to
control the engine throttle speed and gear shift positions of all four engines.
The throttle and shift function is dependent on what engines are running. Refer
to the following table.
