Summary:To provide an outboard motor facilitating a starting operation of an engine even if air is mixed and flowed at a fuel passage.SOLUTION: An outboard motor comprises an engine, a fuel tank, a fuel flow passage, a fuel pump and a controller. The engine includes a fuel injection device. The fuel tank includes an internal space capable of storing fuel. The fuel flow passage is connected to the fuel injection device and the fuel tank. The fuel pump is arranged at the fuel flow passage to supply fuel from the fuel tank to the fuel injection device. The controller controls the fuel pump. The controller judges whether or not a starting condition indicating that air enters into the fuel flow passage is satisfied. When the starting condition is satisfied, the controller releases the fuel injection device and executes an air releasing control for driving the fuel pump.SELECTED DRAWING: Figure 5 【課題】燃料経路に空気が混入しても、エンジンの始動が容易となる船外機を提供する。【解決手段】船外機は、エンジンと、燃料タンクと、燃料経路と、燃料ポンプと、コントローラと、を備える。エンジンは、燃料噴射装置を含む。燃料タンクは、燃料を貯留可能な内部空間を含む。燃料経路は、燃料噴射装置と燃料タンクとに接続されている。燃料ポンプは、燃料経路に配置され、燃料を燃料タンクから燃料噴射装置に供給する。コントローラは、燃料ポンプを制御する。コントローラは、燃料経路に空気が入ったことを示す開始条件が満たされたかを判定する。コントローラは、開始条件が満たされたときには、燃料噴射装置を開放し、且つ、燃料ポンプを駆動するエア抜き制御を実行する。【選択図】図５
