Turning off the starboard outer engine while underway will cause the starboard
inner engine to go into forced neutral/idle. Operation to the inner engine can be
restored by turning the starboard outer engine ignition key to the ON position
and moving the starboard control handle back into neutral position and then
engaging. The inner engine speed and gear shift will then be controlled by the
starboard control handle.
Turning off the port outer engine while underway will cause the port inner
engine to go into forced neutral/idle. Operation to the inner engine can be
restored by turning the port outer engine ignition key to the ON position and
moving the port control handle back into neutral position and then engaging.
The inner engine speed and gear shift will then be controlled by the port control
handle.
Turning off one of the inner engines while underway will have no effect on the
operation of the outer engines.
If a failure should occur while underway which causes the starboard outer
engines into forced neutral/idle condition, the inner starboard engine will also
be forced to neutral/idle. Operation to the inner engine can be restored by
moving the starboard control handle back into neutral and then engaging.
