A method for decelerating a watercraft is disclosed. The watercraft has a reverse gate and a reverse gate actuator operatively connected to the reverse gate for moving the reverse gate between at least a stowed position and a deceleration position. The method includes: receiving, in a control unit, a deceleration signal from a deceleration device position sensor, the deceleration signal being indicative of an actuated position of a deceleration device; controlling, by the control unit, an operation of the reverse gate actuator based at least in part on the actuated position of the deceleration device; and moving the reverse gate from the stowed position to the deceleration position with the reverse gate actuator, the reverse gate actuator being controlled such that a speed of rotation of the reverse gate depends at least in part on the actuated position of the deceleration device.
