Abstract
A method for operating a propulsion device having a propulsor with a propeller, the propulsion device having a base coupled to a marine vessel and being configured to propel the marine vessel in water. The method includes moving the propulsor from a deployed position towards a stowed position, where the propulsor is closer to the marine vessel in the stowed position than in the deployed position, and where the propulsor is configured to propel the marine vessel in the deployed position. The method further includes rotating the propeller so as to fit between sides of the base coupled to the marine vessel when the propulsor is in the stowed position.
