ABSTRACT:
A boat propulsion apparatus having a thrust blade mounted for swinging movement about a generally horizontal axis lengthwise of the boat and for turning movement about an upright axis, and a swash plate drive for simultaneously swinging the blade in a direction crosswise of the boat and for angularly oscillating the blade about its upright axis to sinusoidally vary the pitch of the blade as the blade is swung crosswise of the boat. Provision is made for reversing the direction of angular oscillation of the blade about the upright blade axis relative to the direction of the swinging movement of the blade to enable forward and reverse drive. A variable angle swash plate drive is provided to vary the mechanical advantage of the drive.
