A propulsion unit (1) for a marine vessel, comprising a shell structure (2), a shaft (4) rotatably coupled to a propulsion motor (3) inside the shell structure (2), and a propeller (5) coupled to the shaft (4) outside the shell structure (2). A shaft seal arrangement (6) is provided to engage the shaft (4), such that at least a first seal chamber (6a) is delimited between adjacent seal lips (6') and the shaft (4). A first lubrication arrangement is provided for circulating a first lubricant through the first seal chamber (6a). The first lubrication arrangement (7) further comprises a first lubricant heat exchanger (7e) arranged at least partly outside of the shell structure (2) for conducting the first lubricant therethrough and for transferring heat from the first lubricant to an outside environment of the shell structure (2).
