Abstract
Abstract A number of embodiments of jet propelled watercraft having an improved pedal operated reverse thrust bucket mechanism. The pedal for operating the reverse thrust bucket is positioned so that it is generally flush with the floor area when the reverse thrust bucket is in its forward drive mode and can be depressed into a recessed area of the floor area for effecting trim or reverse thrust operation of the reverse thrust bucket. In this way, the pedal does not obscure the rider's foot area but is still readily accessible for the rider.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
95 words
A watercraft propulsion control for a watercraft having a hull defining an operator's area in which an operator is seated and a floor area on which the operator may place at least one of his feet, said watercraft hull mounting a propulsion unit for propelling said hull and having at least one control element, said floor area being formed with a recessed portion disposed below a surrounding surface area, a pedal pivotally supported within said recessed portion, and an operative connection between said pedal and said control element for foot operation of said control element.
Claim 2
Dependent Claim
95 words
A watercraft propulsion control for a watercraft having a hull defining an operator's area in which an operator is seated and a floor area on which the operator may place at least one of his feet, said watercraft hull mounting a propulsion unit for propelling said hull and having at least one control element, said floor area being formed with a recessed portion disposed below a surrounding surface area, a pedal pivotally supported within said recessed portion, and an operative connection between said pedal and said control element for foot operation of said control element.
