Scott, you can use a trolling motor to drive the pump, just make sure the rest of the system can handle the type of oil you need to use.

 Only
 thing is I have to be sure the oil I use is
 non-conductive.Thanks,Scott

 Scott,
 All oils used on the water should be environmentally
 friendly.  I use vegetable oil in my launch cart.

  Alan, I
  looked into air, but it presents some problems. One is
  compensating it otherwise you will get less preformance
  based on depth. Two is they are not as stiff and have give
  as well as less fine control. Also another problem is if
 you
  used compressed air, you have a limiting factor or you
 could
  use a compressor, but have to have a bank to draw
  from.The main draw back of hydraulic for me was
  the mess and polution factor. Otherwise, hydraulic seems
 to
  be the way to go.I am hoping to come up with a
  manipulator design that can be used on most psubs that is
  easy and affordable.Thanks,Scott

  Hank,why not
  just use air if the pneumatic cylinders are rated for 150
  psi.If they
  are rated for 150 psi it would be assumed that their
  mechanical strengthwould
  match the load they can lift with 150 psi
  also.Is there
  any advantage other than the o ring working both ways to
  stop wateringress,
  as you have said previously. Does anyone else use them in
  placeof
  hydraulic cylinders?Alan

  No problems, Gamma has air
  cylinders and at 1,000 feet the hydraulic pump is set at
  1,100 psi.  Your K sub can have a pressure setting of
 500
  or less and work just fine. Remember, your not lifting a
 lot
  just the arm plus a bit.

   Do you
   have any problem with over pressure though?
  The pnuematic
   cylinders are rated to 150psi
  with air and 1000 psi with

  oil. Thanks,Scott

   hi Scott
   use a
   hydraulic pump just the
  same as if you used hydraulic
   cylinders

           Hank,I know you
   said to use
  pnumatic cylinders  for the manipulator arm.
   What kind of pump do you

  use?Thanks,Scott Waters
