The invention relates to a fluid outlet interface for a personal watercraft, so that the latter can collect and divert a very small portion of the fluid pressurized by said vehicle and thus create a sufficient Venturi effect to drive the emptying of the bilge of said vehicle. The invention also relates to a personal watercraft, or more generally any floating device delivering a pressurized fluid, comprising such an interface.

This new art offers an improvement to conventional surfboards as well as any previous motorized jet surfboards. This application includes an electric powered surfboard equipped with high volume jet drive units that power it forward and significantly improve a surfer's wave fielding and catching ability. Once a wave is caught the drive unit can be shut off by the surfer. Then instantly, two flush fitting glide doors close the jet tube intake openings allowing the surfboard's bottom to return to a planning surface with no protrusions, except for fins, and no water filled jet tubes left open to detract from the surfboard's critical gliding ability when surfing waves. Also, there's a crowned deck shape that allows thin rail sensitivity for turning performance and a motor battery arrangement that provides mass centralization of weight. All this, combined with several wireless control means define this new fine handling motorized surfboard.

A jet propelled watercraft includes a reverse gate that moves to a first position and to a second position. When the reverse gate is in the first position, the reverse gate causes a vessel body to move forward. When the reverse gate is in the second position, the reverse gate causes the vessel body to decelerate or move backward. A velocity mode selector is used to select a normal mode or a velocity mode. The velocity mode has a maximum velocity different from that of the normal mode. When the reverse gate is in the second position and the velocity mode is selected, a controller is configured or programmed to set an upper limit of an engine rotation speed in the velocity mode to be different from that of the engine rotation speed in the normal mode.
