Patent 7314396 was granted and assigned to Honda on January, 2008 by the United States Patent and Trademark Office.
In an outboard motor mounted on a stern of a boat, comprising a power source and a driven unit including a drive shaft connected to the power source and a propeller connected to the drive shaft through a gear mechanism, wherein the power source is detachably connected to the driven unit through an interlock unit, i.e., the outboard motor can be separated into a power unit housing the power source and the driven unit. Owing to this configuration, it becomes possible to provide the outboard motor that is improved in transportability or portability, can be easily mounted on a boat, and minimizes the amount of space required for storage.
