Patent ID: 8490558

Claim:
A watercraft comprising: a hull having a longitudinal centerline; a deck disposed on the hull; a first engine disposed between the hull and the deck; a first jet propulsion unit being connected to the hull on a first side of the longitudinal centerline, the first jet propulsion unit including: a first impeller operatively connected to the first engine; a first inlet disposed upstream of the first impeller; a first outlet disposed downstream of the first impeller; a second outlet disposed downstream of the first impeller; and a first valve selectively fluidly communicating the first inlet with at least one of the first and second outlets; a second engine disposed between the hull and the deck; a second jet propulsion unit being connected to the hull on a second side of the longitudinal centerline, the second jet propulsion unit including: a second impeller operatively connected to the second engine; a second inlet disposed upstream of the second impeller; a third outlet disposed downstream of the second impeller; a fourth outlet disposed downstream of the second impeller; and a second valve selectively fluidly communicating the second inlet with at least one of the third and fourth outlets; a first discharge port and a second discharge port disposed on opposite sides of the longitudinal centerline; a first pipe fluidly communicating the first discharge port with the second outlet of the first jet propulsion unit; a second pipe fluidly communicating the second discharge port with the second outlet of the first jet propulsion unit; a third discharge port and a fourth discharge port disposed on opposite sides of the longitudinal centerline; a third pipe fluidly communicating the third discharge port with the fourth outlet of the second jet propulsion unit; and a fourth pipe fluidly communicating the fourth discharge port with the fourth outlet of the second jet propulsion unit.
