ABSTRACT:
A propulsion mechanism for a boat includes a boat body; a bar being laterally provided on the boat body; a sliding block being provided on and slidable along the bar; a paddle being pivotally disposed on the sliding block and being submerged in water on which the boat body is floated; a restraining device being coupled to said paddle and being rotated in concert with the paddle; the restraining device limiting a rotatable range of the paddle; and two pulling rings being fixed to the sliding block. The sliding block is drawn to move laterally and reciprocally when the pulling rings are alternatively and reciprocally pulled by a user, so that the paddle moves relative to the water and so that a reactive force is produced to propel the boat body.
