Abstract
Disclosed is a passively cooled waterproof propulsion unit for a watercraft comprising a substantially cylindrical housing including an outer wall having an external surface and an internal surface. The cylindrical housing includes a first end cap attached at a first end of the housing. The first end cap includes an attachment interface configured to be mounted to a strut of a watercraft such that at least a portion of the external surface of the outer wall of the housing is configured to contact a fluid surrounding the housing when the watercraft operates within the fluid. The propulsion unit further includes an electric motor disposed within the housing and an electronic speed controller. The electronic speed controller is electrically coupled to the electric motor and configured to provide electrical power to the electric motor to operate the electric motor.
