Air propulsion system for a boat comprises an internal combustion engine for powering a propeller in a single rotational direction. A pivoting mechanism pivots the propulsion system through a 360 degree arc about a transverse horizontal axis from a first position in which the propeller produce a forward thrust, through a second position in which the propeller produces a downward neutral thrust and a turning torque, to a third position in which the propeller produce a reverse thrust, to a fourth position in which the propeller produces an upward neutral t...
What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows: 1. 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 wh...
