Abstract: A propulsion device for the propulsion of a marine vessel includes: a rotatable portion supported by a bearing arrangement with a liquid-lubricated bearing. The rotatable portion has an internal conduit for a liquid for the bearing. The propulsion device transports the liquid for the bearing from a bearing liquid inlet to the internal conduit, and from the internal conduit to a bearing liquid outlet. The bearing liquid outlet is located at a larger radial distance from a rotational axis of the rotatable portion and the rotatable portion has an outlet device with an outlet conduit extending from the internal conduit to the bearing liquid outlet. The outlet device includes a moving part of the bearing, and the outlet conduit extends so as for liquid transported therein to cool the bearing.

Abstract: The invention relates to a method for controlling a water jet propulsion device for the propulsion of a marine vessel, the water jet propulsion device comprising: a conduit extending between an inlet and an outlet; an impeller in the conduit; and a mechanical power provider arranged to deliver power to the impeller; the method comprising receiving a plurality of thrust commands, and controlling a thrust level of the water jet propulsion device in dependence the thrust commands, wherein controlling the thrust level comprises adjusting a position of a deflector arranged to deflect water flowing out of the outlet, characterised by coordinating the adjustment of the position of the deflector with a level of engagement of a clutch, arranged to adjust the delivery of power from the power provider to the impeller, so that the thrust level is substantially continuous in a thrust command domain.
