Abstract: An apparatus for manually moving and steering a small boat, or the like, in both forward and reverse and all directions, which is mounted on the transom or stern of the boat, having a steering post rotated by a tiller 360.degree. in a horizontal plane, with the tiller mounted for up and down pivotal pumping motion to activate laterally connected blades mounted on the lower end of the steering post, with the blades being horizontally joined for flexible return on the non-power stroke and with no flexing on the power stroke, resembling the action of a duck's foot during swimming, each of said blades having a series of individual windows opening to lessen the resistance or drag on the flexing return or non-power stroke and closing for full resistance on the power stroke.
