Abstract

A retractable thruster (1) for a watercraft with a hull (100), comprising; - a motor (2) configured to be fixed relative to the hull, - a propeller (32), - a position actuator (6) configured to reversibly move the propeller relative to the motor between a retracted position and an extended position, wherein the thruster (1) further comprises;- a driving axle (21) configured to be driven by the motor,- a driven axle (31) configured to drive the propeller, - a clutch (4) configured to engage the driven axle and the driving axle when the thruster is in the extended position, and disengage the driven axle from the driving axle when the thruster is in the retracted position.
