PROBLEM TO BE SOLVED: To protect a fuel injection valve against the salinity of water and sea water surely, and attain the protection thereof by a simple structure. SOLUTION: A ship drive device is provided with an engine 13, an intake system member 26 one end of which is opened in the atmosphere and the other end of which communicates with the inside of the engine 13, a fuel injection valve 37 which injects fuel inside at least either the engine 13 or an intake system member 26, and a cowling 14 which covers the engine 13 and the fuel injection valve 37 from outside. An outside air introduction port 81 causing the outside to communicate with the inside is formed in the cowling 14. When the outside air A is sucked by the drive of the engine 13, the main flow of the outside air A deflects the fuel injection valve 37 from the passage 82 in which the same flows from the outside air introduction port 81 toward the upstream end opening 33 of the intake system member 26 in the cowling 14. |
