Abstract

An outboard engine system includes a 4-cycle engine. The engine includes an engine block, a cylinder head coupled to the engine block and having an intake port in one side thereof, a carburetor including a carburetor body disposed on one side of the engine block adjacent the intake port and having an intake passageway, and a bypass-type starting device mounted to the carburetor body, and an intake pipe means which connects the intake passageway and the intake port to each other. At least an upper half of the engine including the carburetor is covered with an engine cover. In such outboard engine system, the bypass-type starting device of the carburetor is mounted to the carburetor body between the intake passageway and the engine block. Thus, it is possible to achieve both of low-speed and high-speed performances and at the same time, to enhance the accuracy of an air-fuel ratio and provide a reduction in fuel consumption and an enhancement in nature of the exhaust gas, and moreover, to avoid an increase in size of the engine cover.
