 Alan,
 Just
 talked to a buddy that installs these pumps.  He said you
 can get many voltage and hp combinations and they are around
 400 dollars.  Also you can get a speed controller.  No
 brushes, no pictures.  :-)  they are about 4.5 in dia and
 2 feet long and shiny ss body.

  Voltage is 220 AC  buy
 it
  gets better!  I discovered the bottom
 end of the motor has
  a very elaborate 
 thrust assembly and a rubber bladder for
 
 pressure compensation.  OMG  just remove the armature
 and
  machine the spline off and screw a prop
 adaptor on and your
  done!

  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.
