Source of props (Fwd)
Ray,
I know you asked us to respond directly to Clint, but I thought maybe others
could use this info...
I was at a boat show the other day and was looking for the same thing as
Clint. My problem is I want to use trolling motors on a PSUB that would be
relatively fast (designed for 8 knots), but the pitch of trolling motors is
too short. Because of the short pitch, you could bolt 10 trolling motors to
a surfboard and it still would not go any faster than pitch*RPM, which in
this case is about 3 knots.
What I saw was a number of suitable-looking props used by manufacturers of
bow thrusters for yachts. The smallest ones are about 4HP, and the props
looked like they were about 5 or 6 inches in diameter, and high pitch. One
of the vendors is called "Side-Power", and they can be reached at
side-power@imtra.com. They sell their smallest props for $57. Another vendor
told me they use props from jet skis, which would open up another avenue of
research for us.
Does anyone else have a supplier of higher-pitch props for trolling motors?

Ray, nice web site, very interesting. I'm looking for submarine props for
an underwater ROV project. In the course of that, I ran across this
interesting Disney working scale sub of the Nautilus - I didn't see it in a
few brief clicks on your web site and thought you might like the reference.

I sell underwater video cameras, but at over 100 feet, it's very hard to get
them pointed in the right direction, so I'm looking for a source of small
props to make a small ROV to control the camera. Our volume isn't large
enough to justify custom prop design and manufacturing so it seems to be a
choice between the smallest trolling motor prop and the largest model boat
props (Octura or Prather seem to be my choices). 3"-4" is about my range.
I wonder if you might have any specific information on prop sources?
Thanks,
