To provide an outboard motor and a ship which can suppress a reduction in engine speed which is not intended by a user due to insufficient supply of fuel to a temporary storage tank resulting from the difficulty in pumping fuel from a fuel tank to the temporary storage tank caused by vaporization of the fuel in the temporary storage tank with an engine being driven.SOLUTION: An outboard motor 102 comprises: an engine 1; a fuel pump 6c for drawing fuel into an outboard motor body from a fuel tank 101a installed at a ship body 101; a temporary storage tank 4 for temporarily storing fuel; a fuel injection device 5 for injecting the fuel stored in the temporary storage tank 4 into the engine 1; a temperature sensor 7 provided at the temporary storage tank 4 and detecting a temperature of the fuel stored in the temporary storage tank 4; and a control unit 8 for performing control to limit an engine speed so as not to exceed a prescribed upper limit speed R1 on the basis of a detection result of the temperature sensor 7, with the engine 1 being driven.SELECTED DRAWING: Figure 3

    【課題】エンジンが駆動している状態において、一時貯留タンク内の燃料が気化することによって燃料タンクから一時貯留タンクに燃料を汲み上げにくくなることに起因して、一時貯留タンクへの燃料の供給不足によるユーザの意図しないエンジン回転数の低下が発生することを抑制することが可能な船外機および船舶を提供する。【解決手段】船外機102は、エンジン1と、船体101に設けられた燃料タンク101aから燃料を船外機本体内に引き込む燃料ポンプ6cと、燃料を一時的に貯留する一時貯留タンク4と、一時貯留タンク4に貯留された燃料をエンジン1内に噴射する燃料噴射装置5と、一時貯留タンク4に設けられ、一時貯留タンク4に貯留された燃料の温度を検出する温度センサ7と、エンジン1が駆動している状態において、温度センサ7の検出結果に基づいて、エンジン回転数を所定の上限回転数R1を超えることがないように制限する制御を行う制御部8と、を備える。【選択図】図3
