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.

Abstract: There is provided a valve timing control system for an internal combustion engine which is capable of reducing an aftershock subsequent to a deceleration shock, for which the execution of cleaning operation is responsible, and increasing the frequency of execution of the cleaning operation. The valve timing control system controls valve timing for opening and closing intake valves and/or exhaust valves by changing the cam phase of each intake cam and/or each exhaust cam relative to a crankshaft. A cam phase-varying device varies the cam phase by rotating a camshaft relative to the crankshaft. An ECU determines whether or not the engine is performing a fuel cut-off operation in which supply of fuel to the engine is stopped during deceleration. The ECU performs cleaning by forcibly driving the cam phase-varying device within a predetermined cam phase range when a predetermined delay time has elapsed after the deceleration fuel cut-off operation is started.
