ABSTRACT:
A lateral thrust drive apparatus for watercraft includes a pair of panel-like blades joined to a respective pair of arms in limited rotational fashion. The arms extend to a pair of parallel drive shafts which extend from a drive housing. Within the housing, a gear assembly drives the shafts in equal and opposite angular excursions, so that the blades diverge and converge in reciprocal fashion. The housing may be removably secured to the stern of a watercraft, and a handle extending from the housing and secured to the gear assembly may be pumped reciprocally to drive the blades and thus propel the craft.
