The invention relates to a thrust generating assembly for a marine vessel, comprising a rotatable device (201) adapted to carry a thrust generating device adapted to generate a thrust by acting on water supporting the marine vessel, wherein the thrust generating assembly comprises a bearing (211, 212) for the rotatable device (201), wherein the bearing (211, 212) comprises an envelope (222) adapted to be fixed to a part of the vessel which is stationary in relation to a rotational axis (R) of the rotational device, wherein the thrust generating assembly comprises a liner (221) which is fixed to the rotatable device (201), wherein the liner (221) is electrically isolated from the rotatable device (201).

A pivot column bearing is provided for a pivotable fin stabilizer of watercraft, the stabilizer having a column pivotable about a vertical axis. The pivot column bearing includes an upper bearing and a lower bearing, the upper and lower bearings being configured to mount the pivot column pivotably about the vertical axis. At least one of the upper bearing and the lower bearing has spherical guide surfaces.
