Contingent Operations

Port Engine Only Operation

The force feedback feature of the steering wheel is only available when the starboard key
switch is in the on position. If the starboard key switch is off or there has been damage to
the starboard electrical system, the port control system monitors the steering wheel.
If only the port side is operational, or only the port key switch is in the on position, the force
feedback system will not provide end stops for the steering wheel. In this case, the drive
will turn in the direction of steering wheel rotation until the mechanical limits of the drive
are reached.
NOTE: If the port electrical system is damaged, the steering wheel will operate normally
with complete force feedback and end stops.
Note that joystick is not available in single‑engine operation. However, Axius features
redundant track pad systems, so Auto Heading mode is still available during single‑engine
operation.
Axius Shift Override—Emergency Procedure
If the VesselView display shows the error message "GEAR POS DIFF" and an engine will
not start or will not shift into gear, there is a problem with the Electronic Shift Control (ESC)
system. If one drive is working, you may operate on one engine and drive.
Using the emergency procedure to manually shift the drive disengages shift control at
the helm. To avoid damage or injury, drive cautiously when a gear is engaged manually.
To stop the drive and its propeller, you must turn the key switch to the off position.
You can disengage the shift actuator to manually shift the drive into neutral for starting and
into forward gear position for operation. Engine speed will be limited to 1000–1200 RPM
while operating in emergency shift override.
To disengage the shift actuator:
1. Turn the ignition switch to the off position and engage the emergency lanyard, if
equipped.
Engine components and fluids are hot and can cause serious injury or death. Allow the
engine to cool before removing any components or opening any fluid hoses.
2. Unplug the shift actuator wiring harness connector.
