Abstract

A propulsion device for marine vessel. A base is configured to be coupled to the marine vessel, the base having sides that extend downwardly from the marine vessel. A propulsor is pivotally coupled to the base and pivotable into and between a deployed position and a stowed position. The propulsor comprises a propeller having a hub with blades extending away therefrom. The propulsor is configured to propel the marine vessel in water when in the deployed position by rotating the propeller. An alignment device aligns the blades of the propeller between the sides of the base when the propulsor is in the stowed position.
