An outboard motor unit for use on small boats and having a primary propulsion engine connected through a clutch to the propeller shaft and an electric motor aligned with and connected to the propeller shaft. The electric motor is connected to a battery through a switch operatively connected to the engine throttle to complete the power connection for the electric motor when the throttle is at a selected proportion of full throttle. The electric motor operates as a motor when the engine is stopped and as a generator when the engine is running.read more
