Inflatable water propeller is an innovative design that combines an air cushion with a traditional propeller to provide users to be engaged in water surface or underwater leisure activities. When the air cushion is pulled out and inflated, it provides a flexible platform which users can comfortably lie on it to enjoy the warm sunshine and slowly slight wind of the water surface, or users can lie prone it to drive the water propeller to the place they want to go. When the air cushion is deflated and pulled back into the storage condition, not only is the water propeller easily carried and stored, but also it can be used as an underwater water propeller.
