The properties of the model of a ship's propulsion mechanism using the so-called Weis-Fogh mechanism are investigated. The above model, proposed in the previous paper by the same authors, consists of one wing in a square channel. The thrust and the drag acting on the wing are measured for various parameters and the efficiency is calculated. The following are found : The thrust becomes negative in the opening stage. In order to raise the efficiency, the ratio of the chord length of the wing to the width of the channel should be rather large, the ratio of the moving speed of the wing to that of the ship should be less than 0.5, and the attack angel of the wing should be small, around 15°~ 30°. The maximum efficiency obtained this time is about 75%.
