Abstract
A center frame 64 fixed to a lower end of a swivel shaft 62 of an outboard engine system by a bolt 79 includes a swivel shaft extension 641 extending downwards from the lower end of the swivel shaft 62, and a core metal 642 which extends laterally from a lower end of the swivel shaft extension 641 and has a lower mount rubber 80 integrally baked thereto. The lower mount rubber 80 is restrained on a rear surface of the extension case 42. Thus, the distance between an upper mount rubber mounted at an upper portion of the swivel shaft 62 and the lower mount rubber 80 mounted at a lower portion of the swivel shaft 62 can be increased without downward extension of the swivel shaft 62 itself to enhance the anti-vibration effect, while avoiding an increase in extra weight and an increase in cost.
