FIELD: shipbuilding.
SUBSTANCE: invention relates to ship propulsion system. Ship propulsion system contains at least one body, geared together to bearing post, installed under hull, and marine propeller, located behind body. Additionally marine propeller allows at least two blades and powered into rotation by connected shaft, connected to motor. Additionally to body there are fixed three guide vanes, forming row, perpendicular to longitudinal axis of body. On body it is located nozzle, which at least partially envelopes marine propeller and row of guide blades. Each blade allows extremity with edge, passing close to inner wall of nozzle, so that marine propeller forms rotor of screw pump, and row is located in area, located between central part of bearing post and marine propeller.
EFFECT: increased coefficient of efficiency of propeller.
