preferably the direction of thrust shown by the linear arrow outlines in fig1 u2013 5 from the propeller can be rotated through a 180 or 360 degree arc as the propeller is rotated about the horizontal axis to propel the air powered boat in one of a forward direction a neutral turning direction and a reverse direction as best shown in fig6 the transverse horizontal axis 5 may lie in a plane that is perpendicular to the longitudinal axis of the air powered boat 12 in instances where the propeller is rotated 360 degree about the horizontal axis to propel the air powered boat control can be accomplished by interposing a universal coupling in the throttle cable this coupling permits axial translation of the throttle cable along its entire length to control the throttle setting as well as unlimited rotational movement of the end of the cable attached to the engine this can be accomplished by mounting one end of the throttle control cable to the coupling body and the other end to a shaft having a head secured in the coupling body for swiveling movement within the coupling body the means for rotating 4 the propeller 2 includes a direct drive 7 controllable by a pilot to rotate the propeller about the transverse horizontal axis 5 to one of the first position second position third position and preferably a fourth position moreover the.
