Abstract

Abstract A control arrangement for a small watercraft of the jet propulsion type having a reverse thrust bucket that is operated by a shift control. The shift control is positioned in relationship to the throttle control such that an operator can operate only one of the controls at a given time. In addition, the throttle control is biased to its neutral position so that when an operator releases his hand from the throttle control to effect a shift, the speed of the watercraft will be reduced.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 155 words
A small watercraft having a hull, a rider's area defining an area to accommodate a rider, a throttle control positioned contiguous to the rider's area and on one side thereof for controlling the speed of said watercraft by the hand of a rider, said throttle control being spring biased to an idle position and requiring the pressure of the hand of the rider to hold the engine speed in any speed other than idle speed, and a drive control for effecting operation of said watercraft in either forward drive mode or reverse drive mode in proximity to that hand of a rider in said rider's area on that one side of the small watercraft said drive control being located on said one side of the small watercraft and spaced a sufficient distance below said throttle control such that a rider can operate only one of said controls with the same hand at a given time.
Claim 2
Dependent Claim 155 words
A small watercraft having a hull, a rider's area defining an area to accommodate a rider, a throttle control positioned contiguous to the rider's area and on one side thereof for controlling the speed of said watercraft by the hand of a rider, said throttle control being spring biased to an idle position and requiring the pressure of the hand of the rider to hold the engine speed in any speed other than idle speed, and a drive control for effecting operation of said watercraft in either forward drive mode or reverse drive mode in proximity to that hand of a rider in said rider's area on that one side of the small watercraft said drive control being located on said one side of the small watercraft and spaced a sufficient distance below said throttle control such that a rider can operate only one of said controls with the same hand at a given time.
Claim 3
Dependent Claim 39 words
A small watercraft as set forth in claim 1 further including a steering handlebar assembly for steering the watercraft, said throttle control being supported on said handlebar assembly and said drive control being positioned contiguous to the handlebar assembly.
Claim 4
Dependent Claim 62 words
A small watercraft a set forth in claim 1 further including a jet propulsion unit for powering the watercraft, and a reverse thrust bucket cooperative with a discharge nozzle of the jet propulsion unit for effecting either forward or reverse thrust to the watercraft, and means for connecting said drive control to said reverse thrust bucket for operating said reverse thrust bucket.
Claim 5
Dependent Claim 29 words
A small watercraft as set forth in claim 3 wherein the jet propulsion unit is positioned in a tunnel beneath a seat of the watercraft in the rider's area.
