The invention provides an encapsulated magnetically geared brushless electric marine propulsion system with the principle components arranged axially around the central shaft. The marine propulsion system includes: the brushless DC motor, comprised of the stator fixed to the central shaft and motor magnets fixed within the motor rotor coupled to the central shaft using precision ball bearings; the high-speed magnetic gear rotor coupled to the motor rotor comprising an alternating array of magnets fixed to a ferromagnetic backing; the environmental barrier which protects the motor and additionally houses pole pieces to modulate magnetic flux; the low-speed magnetic gear rotor coupled to the central shaft and comprised of an alternating array of magnets fixed to a ferromagnetic backing; the propeller coupled to the low-speed magnetic gear rotor; and the shroud coupled to the struts of the motor mounting system.
