The cabin 6 includes a windbreak plate 17 arranged ahead the outboard engine 3 in a plan view. Height D1 of the cabin 6 from a rear end 3a of the outboard engine 3 is 1/2 or more a horizontal distance D2 from the rear end edge 22a of the windbreak plate 17 to a rear end 3a of the outboard engine 3 in longitudinal directions. |
