 Hi Hank

 I agree a jet drive is the
 way to go did you not think that a jet ski drive
 was to small and would only drive a small
 craft. I intend to build a larger
 jet drive
 and compress the water. This will be easy and add power to
 the
 system the jet drive from a jet ski
 would not drive a sub but I am certain I
 can
 overcome the problems by building a larger jet drive and a
 compressor.
 Thank you for your input and I
 will keep you informed as the project un
 folds. 

 Graham

 Graham,
 In the world of marine
 jet drive it is well known that jet drive takes two
 times the horse power to do the same job.  Jet
 drive is well suited to a
 craft that needs a
 shallow draft.  I think you will find it very
 complicated
 to control and it will be very
 inefficient. I have been down this road, I
 love the concept but abandoned it.  If you go
 forward may I suggest you
 start with a jet
 drive.  It is not a simple part to replicate.  The
 impeller
 tolerances are critical.  I have a
 jet unit on the shelf I could donate to
 your
 project.  The jet is from a jet ski. I would consider a
 single rear
 motor on a full gimbal.
 Hank

  Hi   I am near the end of my build  of my k350 and
 have
 started to look at new designs I am 
 interested in building a flyer sub and
 have
 come up with a  design which will include a vectored motor
 drive this
 will  enable my flyer to hover
 and stop where ever I want. I have  designed
 a motor unit which will drive a fan type
 propeller  as an intake this will
 force
 water to the rear of the unit
   where it is
 compressed  then it is forced into ducting  which will
 take 
 the water to four nozzles on the side
 of  the craft. The nozzles are able to
 turn
 three hundred and  sixty degrees  both side are
 independent of one
 another so  rolls will
 be achievable. The reason for a vectored motor is
 you only need one motor source and one power
 pack this will  ease the
 maintenance and
 increase the enjoyment of using  your sub. I am
 interested
 in the clubs thought of this
 kind  of design.  Graham
