摘要: An outboard motor supporting arrangement of a boat includes a stern bracket fixed to a transom of the boat. The stern bracket is U-shaped, and has a flat bottom and left and right side walls extending upwardly from left and right ends of the bottom. Each side wall includes a slant section and a vertial section extending upwardly from an upper end of the slant section. In each side wall, there is further formed a projecting portion projecting outwardly, and extending longitudinally of the boat, for preventing water from be splashed on the outboard motor.
