Abstract
A marine vessel having a hull with a pair of opposite sides disposed at an angle with respect to one another, the opposite sides also disposed at an angle with respect to a water surface. A marine propulsion system is operatively coupled to the hull and includes a pair of impellers associated respectively with the pair of hull sides that rotate within respective impeller planes disposed generally parallel to the hull sides to convey water from at least one inlet though at least one outlet to provide thrust to the vessel. The marine propulsion system may also be contained within an outboard unit mounted to a transom of the vessel.

A marine vessel, comprising:
- a hull having a pair of opposite sides disposed at an angle with respect to one another and with respect to a water surface;
- and
- a marine propulsion system operatively coupled to the hull and including a pair of impellers respectively associated with the pair of hull sides that rotate within respective impeller planes disposed generally parallel to the hull sides to convey water from at least one inlet through at least one outlet to provide thrust to the vessel;
- and
- at least one drive source drivingly coupled to the impellers.
A marine vessel, comprising:
- a hull having a transom and a pair of sides disposed at an angle with respect to one another and with respect to a water surface;
- and
- at least one outboard unit attached to the transom and including a marine propulsion system comprising:
- at least one drive source;
- a housing including at least one inlet and at least one outlet;
- and
- an impeller disposed within the housing that rotates within an impeller plane disposed generally parallel to one of the sides of the hull and at an angle with respect to a water surface to convey water from the inlet though the outlet to provide thrust to the vessel.
