Abstract

An electric propulsion system for watercraft, such as fishing boats, includes an electric motor disposed within a dry cavity of the craft hull, and a prop disposed outboard, below a waterline of the craft. The prop is driven by the motor via a support and power transmission assembly. The motor and prop may be supported by the support and power transmission assembly. A seal assembly is provided at the location where the support and power transmission assembly passes through the hull. A pair of similar propulsion systems may be provided at symmetrical locations with respect to a longitudinal centerline of the hull. Control circuitry permits navigational commands to be input by an operator and translated to speed commands for the propulsion system or systems. The system may remain deployed at all times without the need to retract and stow the prop or motor during transport.
