ABSTRACT:
An improved steering control for a jet propelled watercraft wherein the steering control is provided by at least a pair of pivotally connected nozzle sections with the upstream nozzle section being pivoted first and the downstream nozzle section being pivoted second so as to permit a larger range of deviation in the discharge flow without obstructing the discharge nozzle of the jet propulsion unit. Both mechanical and hydraulic control systems are disclosed.
