ABSTRACT:
A jet propelled watercraft has a brake which the driver of the watercraft can use to decelerate forward motion of the watercraft. The brake mechanism preferably includes a reverse gate that allows watercraft steering to be consistent when the watercraft is accelerating or cruising with the reverse gate in a fill-up position as when the watercraft is decelerating with the reverse gate in a full-down or partial-down position. The positioning of the reverse gate during operation of the watercraft is adjusted in accordance with the state of hand operated actuators for a forward throttle control mechanism and a brake control mechanism. Preferably, an electronic controller receives a signal from the control mechanisms and outputs a control signal that directs a servomotor to move a reverse gate control cable or linkage to position the reverse gate. Forward thrust can be increased by proportionally closing the actuator for the forward thrust control mechanism. In addition, reverse thrust or braking thrust can be increased by proportionally closing the actuator for the brake control mechanism.
