PROBLEM TO BE SOLVED: To provide an outboard engine for a two-cycle two-cylinder engine having a low lateral width. SOLUTION: An intake manifold 46 comprises an air introduction port 51 connected to a carburetor 47; an upper air outlet 52 connected to the upper crank chamber 37 of an engine; and a lower air outlet 53 connected to a lower crank chamber 38. The center of the air introduction port, the center of the upper air outlet, and the center of the lower air outlet are positioned approximately in the same vertical plane, and the air introduction outlet is formed in a lateral symmetrical shape. A first flow passage 61 is formed between the air introduction port and the upper air outlet. A partition plate is arranged in the middle of the first flow passage and a second flow passage 64 is branched from a part closer to the air introduction side than the partition plate toward the lower air outlet. Further, the lower end of the upper air outlet is positioned lower than the lower end of the air introduction port. |
