Abstract
A hybrid type vessel propulsion apparatus includes an engine, an electric motor, a propeller shaft that rotates together with a propeller, a first transmission path, a second transmission path, and a third transmission path. The first transmission path transmits power of the engine to the propeller shaft. The second transmission path transmits power of the electric motor to the propeller shaft without transmitting the power through the first transmission path. The third transmission path transmits a portion of the power of the engine, which has been transmitted from the first transmission path to the propeller shaft, to the electric motor in order for the electric motor to generate electricity.
