Abstract
A vessel propulsion apparatus includes an engine, an electric motor located farther forward than a propeller, a propeller shaft, a first transmission that defines a first transmission path extending from the engine to the propeller shaft to transmit power of the engine to the propeller shaft along the first transmission path, and a second transmission that defines a second transmission path, different from the first transmission path, extending from the electric motor to the propeller shaft to transmit power of the electric motor to the propeller shaft along the second transmission path.
