Rudder Position Sensor - M81105

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Hello Below,

Raymarine's M81105 Rotary Rudder Reference Transducer does indeed support approximately 120 degrees of rotation. However, a properly installed Raymarine autopilot linear drive will limit rudder movement to +/- 30 degrees. Similarly, Raymarine's autopilots will not drive a rudder more than approximately +/- 30 degrees when operating in Auto or Standby modes. Additionally, should
- an Evolution or SPX autopilot be installed onboard, and
- a drive unit other than a linear drive be installed, and
- the rudder be moved more than approximately +/- 50 degrees,
then the autopilot will no longer report rudder angle, requiring that the autopilot be restarted (i.e. switched OFF and then switched ON again) to resume correctly reporting rudder angle.
