ABSTRACT:
Disclosed is a mounting structure of a propulsion device for an inflatable boat, including a propulsion assembly, which comprises a power device and a driven propeller; a sleeve body, whose internal diameter is larger than the longitudinal length of the propeller of the propulsion assembly so as to allow the easy passage of the propeller of the propulsion device through the sleeve body; a mounting hole securely devised in the hull, the hole being provided near the stern of the inflatable boat in accordance with the habitual practice as well as for convenience sake, and the internal diameter being larger than the external diameter of the sleeve body; a power device supporting element, which is secured to the sleeve body so that when the propeller of the propulsion assembly passes through the sleeve body it can maintain the power device of the propulsion assembly above the flange of the cover of the sleeve body; and a set of direction control levers to turn the propeller of the propulsion assembly so as to control the direction of the boat; when the sleeve body passes through the mounting hole, the hull is inflated to tightly hold and secure the sleeve body.
