A drive assembly for a marine propeller drive unit has two concentric drive shafts for carrying a respective propeller. A space between the drive shafts is lubricated with liquid lubricant pumped into the space by a pump. The outermost drive shaft is provided with at least one protrusion protruding radially inwards from an inner surface of the outer drive shaft. The inlet of the secondary fluid channel is provided in said at least one protrusion at a first radial level offset radially inwards from the inner surface of the outer drive shaft such that liquid lubricant at said first radial level is able to lubricate bearings between the outermost drive shaft and the innermost drive shaft.
