Abstract
An outboard motor has an internal combustion engine installed in an engine compartment defined by an engine cover. The engine's intake air inlet is formed by an air intake duct, which communicates with an air intake space outside the engine compartment. The engine cover includes an upper cover with a receiving ring fitted on the air intake duct. The receiving ring and the intake duct form an overlapping part in which the ring and the duct overlap each other in the direction of flow of combustion air. The overlapping part has a sealing member therein which forms a seal between the air intake space and the interior space of the engine compartment. The sealing structure does not require high dimensional precision to form a required sealing property between the engine cover and the air inlet of the engine intake system. The sealing structure minimizes any influence of engine vibrations.
