An engine E is received vertically in an engine room 36 covered by an engine cover 4, and a generator 62 is arranged in a position above a front end of a crankcase 7 of the engine E and facing an opening 101 formed at a front of belt covers 10, 11. An air flowing from an air intake port 41 formed at a rear, upper portion of the engine cover 4, toward an intake opening 791, of an intake silencer 76 provided at a front, lower end of the engine room 36 cools the generator 62 disposed in a path of flow. A part of air in the engine room 36 is introduced into an interior of the belt covers 10, 11 through the opening 101 to be discharged outside from a ventilation port 751, and at that time the generator 62 is cooled by the air which passes through the opening 101.
An outboard engine system comprising an engine (E), an intake system auxiliary (76) and a generator (62) which are accommodated within an engine room (36) covered with an engine cover (4) having an air intake port (41), characterized in that said generator (62) is disposed in an intermediate portion of a path of air flow from said air intake port (41) to an intake opening (791) in said intake system auxiliary (76).
An outboard engine system comprising an engine (E), an intake system auxiliary and a generator (62) which are accommodated within an engine room (36) covered with an engine cover (4) having an air intake port (41) and a ventilation port (751), characterized in that said generator (62) is disposed in an intermediate portion of a path of air flow from said air intake port (41) to said ventilation port (751).
An outboard engine system comprising an engine (E), an intake system auxiliary (76) and a generator (62) which are accommodated within an engine room (36) covered with an engine cover (4) having an air intake port (41) and a ventilation port (751), characterized in that said generator (62) is disposed in an intermediate portion of a path of air flow from said air intake port (41) to an intake opening (791) in said intake system auxiliary (76) and in an intermediate portion of a path of air flow from said air intake port (41) to said ventilation port (751).
An outboard engine system comprising an engine (E) accommodated within an engine room (36) covered with an engine cover (4), and a generator (62) disposed on an axis different from that of a crankshaft (15) of said engine (e) and driven by said crankshaft (15), characterized in that said generator (62) is disposed between a front or rear surface of an engine block (6, 7, 8) and an inter surface of said engine cover (4) wherein said generator (62) is disposed in an intermediate portion of a path of air flow from an air intake port (41) in said cover (4) to an intake opening (791) in an intake system auxiliary (76).
