If the vessel type is set to STERN DRV (I/O or stern drive), you will see

AUTO RELEASE
Response level
This is the default response setting. The response level controls the
relationship between the autopilot's course keeping accuracy and the
amount of helm/drive activity. You can make temporary changes to
response during normal operation (see page 7).

Options
AutoSeastate on (Automatic deadband) = default
• autopilot to gradually ignores repetitive boat movements
and only react to true variations in course
• provides the best compromise between power
consumption and course keeping accuracy
AutoSeastate off (minimum deadband)
• provides tighter course keeping
• increased power consumption and drive unit activity
AutoSeastate off + counter rudder yaw damping
• provides tightest possible course keeping by introducing
counter rudder yaw damping
