Abstract: A small boat bow thruster which includes a port and starboard discharge nozzle forwardly mounted through the hull of the boat above the water line. Water from an inlet port located below the water line of the boat is drawn by a pump through conduits to the discharge nozzles. The pump is a bi-directional positive displacement pump which can feed either the starboard or port discharge nozzle depending on the direction of pump rotor rotation. The pump is powered by an electric motor capable of running in a normal or reversed mode and which is controlled by an activation switch manually operated. Water is discharged through the port or starboard nozzle above the water line of the boat when the system is activated. The bow is thrust sidewise in the direction opposite of the nozzle discharge allowing slow and controlled maneuvering of the boat in tight spaces.
