Abstract
An outboard motor includes an engine, a fuel pump to draw fuel into an outboard motor body from a fuel tank installed on a hull, a temporary storage tank to temporarily store the fuel drawn into the outboard motor body by the fuel pump, a fuel injector to inject the fuel stored in the temporary storage tank into the engine, a temperature sensor on the temporary storage tank to detect a temperature of the fuel stored in the temporary storage tank, and a controller configured or programmed to perform a control to limit an engine speed to no more than a predetermined upper limit rotation speed based on a detection result of the temperature sensor while the engine is running.
