Patent ID: 7090549

Claim:
An air powered boat having an air propulsion system comprising: a) means for propelling the boat in every one of a forward, reverse and at least one neutral thrust turning direction having an engine powering a propeller in a single rotational direction, said engine is an internal combustion engine, said means for propelling includes a pivoting mechanism for pivoting the propeller about a transverse horizontal axis from a first position in which the propeller produces a thrust to move the boat forward through a second position in which the propeller produces a downward neutral thrust to a third position in which the propeller produces a thrust to move the boat in reverse; b) a securing mechanism attaching the means for propelling to the boat; and c) a fuel system with a fuel reservoir supported on a frame at an elevation above the internal combustion engine so that the fuel is fed to the engine by gravity when the propeller is in any pivoted orientation.
