Center Engine Control Switch
This is a switch to link or unlink the center
engine with the port engine.
When the link is selected, the CENTER CTRL
LED comes on.
To switch between link and unlink modes, set
the remote control handle to the neutral position
and operate the center engine control switch.
When the engines are unlinked, the center
engine is at the neutral position and the engine
speed is kept at idling.
When unlinking is selected, the CENTER CTRL
LED goes out.
Only when all the remote control handles are at
the neutral position, this switch is enabled.
NOTE:
When the main switch is turned ON, link is
automatically selected.
If this switch is operated with the remote control
handle at a position other than neutral, the
CENTER CTRL LED blinks and the buzzer
sounds at the same time.
