that with two parallel rudders, water jets or other propulsion

Yes
Repeat the same calibration procedure for “Cal rudder drive 2”,
and apply a little offset to the opposite direction when setting the
zero point.
Note that every time the “Voltage output” display is shown, the
steering system must be set for autopilot control, either manually
or via “System select”. Refer to “System Select” in the AP50
Installation Manual.
Note!
Rudder Zero = 0 will give full range and equal level of the
signal to each side, but will be limited by the Maximum
rudder setting. If Rudder Zero is set different from 0, part
of the available signal range is used for permanent offset
and the remaining range available for control will
therefore be less in one direction (ref. Figure 3-2 for
details).
