Abstract
An arrangement and a method for controlling a propeller drive on a boat including a propeller drive suspended in a housing that can rotate, a servo motor which is arranged to rotate said rotating housing, a control unit which is arranged to control the servo motor in response to an input signal from a control device, corresponding to a required position of the rotating housing.

An arrangement for controlling the angular position of a propeller drive (5) on a boat comprising a propeller drive (5) suspended in a housing (6) that can rotate, a servo motor (26) which is arranged to rotate said rotating housing (6), a control unit (31) which is arranged to control the servo motor (26) in response to an input steering signal from a control device (30), corresponding to a required position of the rotating housing (6), characterized in that the arrangement comprises a safety brake (35) which is arranged to lock said rotating housing (6) to prevent rotation in the event of the detection of a fault in the angular position control of the propeller drive (5).
A method for controlling the angular position of a propeller drive in a boat comprising the following method steps:
- controlling (S10) the angular position of a propeller drive (5) suspended in a rotating housing (6) by means of a servo motor (26) which rotates said rotating housing (6) in response to an input signal from a control device (30), corresponding to a required position (θ) of the rotating housing (6), characterized in that a safety brake (35) locks said rotating housing (6) to prevent rotation, in the event of the detection of a fault in the angular position control of the propeller drive.
