The invention relates to a propeller assembly (10) for a marine vessel (1), comprising: a body (12) comprising a duct (20) having a longitudinal axis (L) and a first end (20.1) and a second end (20.2); a support structure (14) for the propeller (16), the support structure comprising a propeller shaft (18) at a centerline of the duct (20); a propeller (16) positioned in the duct (20) and attached to a propeller shaft (18), where the propeller (16) comprises at least three blades (22) and a hub (24) supported to the shaft (18), and further comprises a circular rim (26) to which the radial ends (22 ') of the blades of the propeller are attached, where there is provided a circumferential groove (28) in which the radial ends (22') of the blades of the propeller (16) are fixed to the hub (24). A circumferential groove opening inside the pipe between a first end (20.1) and a second end (20.2), a circular rim (26) being arranged to extend radially into said groove; and at least one gas inlet (30) arranged to lead to the slot (28). The invention also relates to a transverse tunnel thruster and a steerable azimuth thruster provided with the thruster assembly.
