Well here it is I found the utility patent after five cups or coffee. I wish I hadn't drank all that coffee now that I see there isn't a head in this sub I'm stuck in for the night. :0' I guess I could use the coffee pot. I feel like a fish in a fish tank down here.
And yes folks we have pictures or drawings as well on USPTO site just click on the Images tab

Propulsion systems for submarine vessels
A propulsion system for a submarine vessel includes a thruster including a magnetic flux generating stator, a shaftless propellant rotor, electrical conductors to supply electrical current to the thruster, an electronic controller to regulate such electrical current and a mounting unit to attach the thruster to the vessel. The stator includes a plurality of magnetizable pole pieces each associated with windings of conductive wires electrically connected to a power supply via the controller. The rotor includes a propeller ring containing a plurality of permanent magnets to be torqued by the magnetic flux from the stator pole pieces and a plurality of propeller blades. The rotation of the rotor (armature) provides position signals to the controller which then energizes the proper field windings of the stator to continue the motion and provide full torque regardless of rotor speed.
