PURPOSE:To ensure a predetermined antivibration property even if a casing of a propelling unit is made compact, by coupling a lower portion supporting means with the casing of the propelling unit and coupling an upper supporting means with an engine body of the propelling unit. CONSTITUTION:To both upper and lower ends of a steering shaft 15 are connected propelling units 18 through upper and lower supporting means 16, 17. The lower supporting means 17 is coupled with a casing 19 of the propelling unit 18 on a predetermined height level without being sunk in the water on sail to produce sailing resistance, and the upper supporting means 16 is coupled with an engine body 20 of the propelling unit 18. And the upper supporting means 16 is formed to sandwich resectively antivibration rubbers 28, 34 between horizontal and vertical supports 22, 30 formed integrally with a steering handle 21 on the upper end of the steering shaft 15 and a support 24 and a support bracket 32 provided on the engine body 20. |
