Abstract
Abstract The following specification discloses a mechanism for attachment to a water jet pump as used for propelling boats which has as its object the deflection of the water jet at an angle to the path of travel of the boat. The mechanism comprises a chain and cable or a pair of gears controlled by a steering member to deflect the jet of water through a variable path at the rear of the boat to thereby provide a thrust to the boat in the opposite direction and allowing the boat to be moved out of a normal forward path.

Claim 1
Independent Claim
158 words
In a water craft propelled by a jet of water discharged from its' stern and having a water outlet means rotatably mounted at the stern of the discharge housing of a water pump means for controlling the deflection of the jet of water to starboard or to port of the stern of said craft, the combination comprising; a water deflector rotatably mounted beneath said outlet and moveable therewith to direct said jet of water downwardly and forwardly of said craft; a first gear member fixed to the lower side of said housing and intermeshing with and driving a second gear member fixed to said deflector thereby to allow said deflector to rotate about said outlet; and control means for rotating said outlet and said deflector together to provide a cumulative deflection forward of said craft from said deflector to allow water to discharge at an angle of at least 90° to the course of travel of said craft.
