Ahhhhh! OK, in that case ceramic seals would
be good because you are correct, you'd need to pick one appropriate for 200 psi
or better. Here's something to look at... "style 2" in
316SS.
Alec the tank is capable of the 200 psi, but my compensation is the
concern.
I am planning on just pre loading the tank with hp before dive and
just leave it
over pressure. This seems a lot easier than rigging a regulator to
do it.

Hi Dean,
The compressor tank is probably built
for 200 psi internal, but if you're planning to pressure compensate it,
then an ordinary lip seal should do. It's just the pressure differential that
will act across the seal. Pressure compensated trolling motors do fine
with their standard lip seals.
As far as bearings are concerned, your
question is very timely for me. I'm building by assemblies, and have been
collecting parts for the next one which happens to be my prop shaft,
seals, tunnel, and kort nozzle. I've gone for two conical bearings
mounted in opposition. That way I have a thrust bearing for forward and
another for reverse. But I'm curious what others have used for this, and still
have time to make changes since I haven't built it yet. I expect to start on
this assembly in about a week. Any opinions?
thanks,
Alec

I am trying to figure out what to use for a shaft seal for my
main motor
I am planning on manually pressurizing a pod made from and air
compressor
tank. So I guess what I am looking for is a shaft seal that will
take up to 200 psi
internal pressure, this is way out of my
expertise.
Any suggestions on what to look for
That and do any of you use bearings for the propeller shaft? All
I seem to see
are just bushing types, I am using a 12hp dc motor and it seems
to me that a
thrust bearing is in order.
