Abstract

The invention relates to a propulsion device for an ice-going vessel. Said device comprises a propulsion device attached to the hull (1b) of said vessel, power transmission means (2b) for transmitting power from the vessel's engine to said propulsion device, a propeller (3b) mounted in said propulsion device, and a nozzle (6b) enclosing the propeller (3b).
According to the invention, said power transmission means (2b) are placed to the rear side of said nozzle (6b) with respect to the flow direction.
