A boat propulsion device includes an engine, a fuel tank, a fuel path, a fuel pump, and a controller. The engine includes a fuel injection device. The fuel tank includes a fuel storage region configured to store fuel. The fuel path is connected to the fuel injection device and the fuel tank. The fuel pump is disposed in the fuel path and is configured to discharge the fuel stored in the fuel storage region to the fuel injection device. The controller is configured and/or programmed to control a load on the fuel pump. The controller is configured and/or programmed to include an empty-fuel condition detector configured to detect that the fuel stored in the fuel storage region has become a predetermined remaining amount or less based on a variation in the load on the fuel pump.
