[PSUBS-MAILIST] thruster discovery

[hank pronk via Personal_Submersibles]

I have just dismantled a submersible well pump.  As I thought it is fluid filled and all SS, it seems like it is filled with anti freeze not oil.  This would make a beautiful thruster.  The output shaft is splined and a simple adaptor to a prop and your done, also a thrust washer should go in.  The armature rides on bushings, not bearings.  The wires are potted and plug into the motor interior. This is very interesting and should be explored more.
