<p>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 warer 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.</p> |
