Retractable propulsion container with thruster

The present invention relates to a propulsion container (1) comprising space for a propeller driver, the propulsion container having a first end (3) and a second end (4), said second end (4) having a surface; a trunk (5) inside which the propulsion container (1) is moveably mounted, allowing the propulsion container (1) to be moved between a first position and a second position; a first sealing arrangement (6, 7) arranged to seal, in the first position of the propulsion container, a first gap between the propulsion container (1) and the trunk (5) to define a first watertight space on a second side of the first sealing arrangement, and a second sealing arrangement (8) arranged to seal, in the second position of the propulsion container, a second gap between the propulsion container (1) and the trunk (5) to define a second watertight space on a second side of the second sealing arrangement.
