Abstract: A personal watercraft includes a hull having a bottom wall and a side wall extending upwardly from the bottom wall. The bottom and side walls define an interior volume of the hull. A battery pack includes a plurality of battery modules. The battery pack is positioned within the interior volume. A flotation body is positioned within the interior volume between the battery pack and at least one of the bottom wall of the hull and the side wall of the hull.

Abstract: A personal watercraft comprises a deck having coupled thereto a hull defining a bottom wall, a rear wall and a water intake extending from the bottom wall to the rear wall, and a jet propulsion system. The jet propulsion system comprises a housing coupled to the rear wall and defining an inlet to receive water from the water intake, a venturi, and an outlet to expel the water, and comprises a rim-driven motor disposed within the housing between the inlet and the venturi. The rim-driven motor defines a center axis and comprises a stator coupled to the housing, a rotor disposed radially inwardly of the stator relative to the center axis, and impeller blades coupled to the rotor and projecting towards the center axis, the rotor and the impeller blades rotatable about the center axis to draw the water via the inlet and expel the water via the outlet.

Abstract: A jet propulsion system includes a housing and an impeller positioned within the housing interior. A nozzle is positioned at least partially downstream of the housing outlet and a deflector gate is positioned within the nozzle interior. The deflector gate has a first end, a second end and a pivot provided at the first end. The deflector gate is pivotable relative to the nozzle about a pivot axis defined by the pivot between a default position and a deflector position. The deflector gate in the default position having the second end downstream of the first end, and in the deflector position deflecting at least some of the water out of an opening of the nozzle in an upstream direction.

Abstract: A jet pump housing is mountable to a hull of a personal watercraft. The jet pump housing comprises a body extending between an inlet and an outlet. The body has an inner wall delimiting an interior of the body and an outer wall. The inner wall and the outer wall are configured to be exposed to water during use of the personal watercraft. The body is shaped and sized to allow water to flow into the interior via the inlet and to expel water from the outlet. The body has one or more fluid passages positioned between the inner wall and the outer wall. The one or more fluid passages are fluidly isolated from the water and are in heat exchange relationship with the water via one or both of the inner wall and the outer wall.

Abstract: There is described a watercraft comprising a housing having a hull and a deck, the hull shaped to cause the watercraft to operate in a displacement state and a planing state, a powerplant in the housing, and a propulsion device drivingly engaged to the powerplant to generate a propulsive force to propel the watercraft. A controller is configured for monitoring an operational parameter of the watercraft, the watercraft having a range-efficient operating regime following a transition of the watercraft from the displacement state to the planing state, the operational parameter having an optimal state for the range-efficient operating regime. A user interface is coupled to the controller and configured for providing a visual indication of a status of the watercraft in relation to the range-efficient operating regime.
