Abstract
An outboard motor includes a propeller, an engine, a transmission, a casing, an engine cooling mechanism, a cooling jacket, a water intake opening, and a transmission coolant flow channel. The casing is arranged to house the transmission. The engine cooling mechanism is arranged to cool the engine by supplying the water taken into the casing from the water intake opening to the engine via an engine coolant flow channel. The cooling jacket is arranged adjacent to the transmission inside the casing. The water intake opening is provided at a predetermined position of the casing to which a dynamic pressure is applied by water flow when a marine vessel travels. The transmission coolant flow channel is arranged to connect the water intake opening and the cooling jacket. The transmission coolant flow channel is provided independently of the engine coolant flow channel.
