Abstract
A steering arrangement for a watercraft that includes a jet propulsion unit having a jet propulsion unit housing. The housing includes an inlet end and a discharge end with a propeller provided therebetween for drawing water from the inlet end and discharging the water in the form of a pressurized jet stream to the discharge end. The discharge end includes a fixed nozzle through which the jet stream of pressurized water flows. A pivoting nozzle is pivotally coupled to the discharge nozzle for guiding the jet stream of pressurized water for steering operation of the watercraft. A seal is effected between the discharge nozzle and steering nozzle upon steering action of the pivoting nozzle so as to prevent a generally forward flowpath of water between the fixed nozzle and pivoting nozzle.
