A ship propulsion device includes: a motor; a battery; a temperature-adjustment-water flow path including a first route passing through a first exchanger capable of exchanging heat with the battery; a route switch unit switchable between a state which permits a flow of water to the first route and a state which restricts the flow of the water to the first route; a first temperature sensor which detects a temperature of the battery; a second temperature sensor which detects a temperature of the water; and a controller which controls the route switch unit. At least one of (i) when the battery temperature exceeds an upper limit value and the water temperature is lower than the battery temperature or (ii) when the battery temperature is lower than a lower limit value and the water temperature exceeds the battery temperature, the controller sets the route switch unit to the permitted state. At least one of (i) when the battery temperature exceeds the upper limit value and the water temperature exceeds the battery temperature, or (ii) when the battery temperature is lower than the lower limit value and the water temperature is lower than the battery temperature, the controller sets the route switch unit to the restricted state.
