A propulsor for a marine vessel is described. The propulsor includes a plurality of blades extending from a rotary housing. The blades are distributed around a blade pitch circle diameter of the rotary housing. A mounting plate rotatably mounts the rotary housing to a hull of the marine vessel. A slewing bearing includes a driven ring with a driven gear that is fixed to the rotary housing and a stationary ring fixed to the mounting plate. A diameter of the slewing bearing is at least 0.4 times the blade pitch circle diameter. The propulsor includes a main electric motor with a drive shaft mechanically connected to a driving gear. The driven gear of the slewing bearing and the driving gear define a single-stage transmission gear with a transmission ratio between 5:1 and 15:1.
