摘要： PROBLEM TO BE SOLVED: To prevent vibration transmitted to a steering handle from an engine by forming a structure that an elastic member can freely vibrate in clearance between a steering handle and the engine side, and arranging the abutting part capable of abutting to the engine side on the steering handle side. SOLUTION: Vibration of an engine is transmitted to a steering handle 16 through a steering bracket 18 and a vibration control member 50 from an upper case. Here, the vibration control member 50 is constituted so that both ends of an outer cylinder 50c are opposed through clearance (d) to the abutting part 16c of a fixing plate 51 and the steering handle 16. Therefore, the steering bracket 18 can freely vibrate between the fixing plate 51 and the base part 16b. Therefore, a member having a small spring constant can be adopted as an elastic member 50b. As a result, resonance of a low frequency is generated to reduce vibration is steady operation having a high engine speed in the steering handle part.

摘要： PURPOSE:To prevent adhesion of salinity on an outside face of an upper casing by providing a cooling water passage leading cooling water to the vicinity of the inside face of the upper casing outside wall part in an exhaust pipe extending into the upper casing. CONSTITUTION:Cooling water cooling an engine 3 is discharged from a cooling water passage 3c in the vicinity of the exhaust passage to a cooling water passage 28 in an exhaust pipe 23, and then, is let flow into a water jacket 24 from the cooling water passage 28. In this process, the cooling water discharged from the cooling water passage 28 is sprinkled on a rear wall 2c, as the lower opening of the cooling water passage 28 is positioned in the vicinity of the rear wall 2c in an upper casing 2. Therefore, the exhaust pipe 23 is cooled down by the cooling water discharged from the cooling water passage 28, and the cooling water from the cooling water passage 28 is sprinkled on the upper casing 2 for cooling it down. Consequently, the upper casing 2 can be cooled down with the exhaust pipe 23 by means of the cooling water, and sea water adhering on the outside face of the upper casing 2 is swept away, so that no salinity remains on the outside face.

摘要： PROBLEM TO BE SOLVED: To discharge exhaust smoothly at an engine low speed rotation time, and prevent the support member vibration of an outboard engine by causing an expansion chamber partitioning formed by a case member, a support member, and upper and lower mounts to communicate with the atmosphere. SOLUTION: The propulsion unit 7 of an outboard engine is equipped with an upper case 9 supported by a swivel bracket 6 so as to be free in turning, a lower case is fitted to the lower part of the upper case 9 so as to form a casing on the whole. At an engine low speed rotation time such as idling operation or the like exhaust B flows as shown by a solid line arrow sign from an exhaust passage 18a formed in the oil pan coupling part 9a of an upper case 9 to a main expansion chamber 66. The same flows to a sub expansion chamber 67 via the exhaust passage 18 of a cylinder part 9b and an exhaust hole 67a, and is discharged to the atmosphere from an atmospheric exhaust hole 67b. Thereby, the exhaust is smoothly discharged even if the lower part mount 20 is in the water so that the occurrence of noise and vibration can be prevented.
