PROBLEM TO BE SOLVED: To provide a vibration control support structure of an outboard motor simple in structure, small and inexpensive. SOLUTION: A lower mount 66 to elastically support an extension case 42 of an outboard motor on a lower end of a swivel shaft 62 is furnished with a center frame 64 fixed on the lower end of the swivel shaft 62 by a bolt 79 and a pair of lower mount rubbers 80 fixed on outer peripheral parts of its both left and right ends by baking, and these lower mount rubber 80 are fitted in a rubber storage part formed on a rear surface of the extension case 42 and constrained by a cover member 81. As the lower mount rubbers 80 are fixed to the center frame 64 by baking, fixed parts such as a bolt and a nut and a space for working to operate those fixed parts are eliminated, and it is possible to contribute to miniaturization and reduction of cost by simplifying a structure of the lower mount 66 of the outboard motor.
