Abstract: A propulsion unit includes a housing supported on a vessel. A propeller shaft extends in the housing. The propeller shaft is rotatably supported with a first bearing and a second bearing. A propeller is attached to at least one end of the propeller shaft. The first bearing includes a first radial bearing and a first thrust bearing. The first radial bearing is a sliding bearing positioned axially inside the first thrust bearing. The first bearing is positioned at the first end of the housing and the second bearing being positioned at the second end of the housing or vice a versa.

Abstract: An arrangement and a method for sealing a propeller shaft of a marine vessel. The arrangement includes a propeller shaft rotatable supported with at least one bearing, a bearing arrangement, a first lubrication arrangement including a first lubricant circulation line for conducting first lubricant to and from the bearing arrangement, a shaft seal arrangement for sealing the propeller shaft against sea water, and a second lubrication arrangement including a second lubricant circulation line for conducting second lubricant to and from the shaft seal arrangement. A first heat exchanger is in thermal contact with the first lubricant circulation line and in thermal contact with the second lubricant circulation line.
