Abstract

A system for steering a watercraft propelled by a water jet includes a control lever (16) supported to pivot rightward and leftward about a first axis (48), a nozzle supported on the watercraft to pivot rightward and leftward and through which water is discharged from the watercraft, first and second cables (54, 56), and a steering module interconnected by the cables to the control lever and connected to the nozzle (34), supported to pivot laterally about a second axis and to pivot the nozzle laterally in response to pivoting of the control lever about the first axis.

Abstract

A system for driving a water induction and discharge system of a watercraft (10) propelled by a water jet includes a water impeller (32), an engine (28) including a driven shaft and a first chamber (70) for containing engine oil, a second chamber (76) for containing engine oil, a pinion (62) secured to the driven shaft and located in the second chamber, a gear (60) located in the second chamber, engaged with the pinion and driveably connected to the water impeller, and a dam located in the second chamber for limiting oil flow across the dam (102) into the oil contained in the second chamber.

• B63H 11/08 - Marine propulsion by water jets the propulsive medium being ambient water by means of pumps of rotary type

Abstract

A watercraft propelled by a water jet includes an sealed hull portion including an upper deck and a bottom surface, an engine compartment located behind the sealed hull portion and containing a propulsion and steering system including an engine, a bladed impeller driven by the engine for inducting water and forcing the inducted water away from the craft through a directionally displaceable nozzle, and a control lever located on the upper deck including an engine throttle control and a steering control for adjusting the directionally displacement of the nozzle.

Abstract

A device for cutting weeds carried by water inducted into a housing includes an intake, an outlet, an impeller for pumping water from the intake to the outlet as the impeller rotates about an axis, the impeller including a blade formed with a leading edge facing the intake, and a baffle secured against movement and including a cutting edge located adjacent the leading edge when the leading edge rotates to the location of the cutting edge.
