<DIV>Hi Hank,</DIV>
<DIV>I'm still not convinced. You would also have to have some sort of
bearing for reverse.</DIV>
<DIV>Are you talking about a washer as your main thrust bearing? I know
the Minnkotas don't have more than a washer as a thrust bearing for
reverse.</DIV>
<DIV>Are the original bearings that you are talking about using OK for
sea water? </DIV>
<DIV>Technadyne talks about using a water lubricated bearing on their
thrusters.</DIV>
<DIV>Obviously it works for them & their units are used on some
expensive subs & ROVs, but</DIV>
<DIV>they have modified the technology for their application & the
price tag for a thruster is huge.</DIV>
<DIV>Look forward to your experimentation in this field.</DIV>

<DIV><SPAN>The impeller that is submerged in water is fixed to a shaft
that is supported by a bearing on each side. I would use
the original bearings and put a thrust washer of appropriate
material on the shaft shoulder. One could simply remove the
impeller and drill through the pump housing right through the
bearing. Then replace the original shaft with a longer shaft
machined with a shoulders. The protruding shaft can be machined to
accommodate the appropriate propeller. Or you could machine a nice
nose cone to replace the outer pump body and use the original
bearing. <VAR id=yiv842623538yui-ie-cursor></VAR></SPAN></DIV>

<DIV>Thanks Hank,</DIV>
<DIV>I only looked at these couplings yesterday, but it seemed that the
bearings would be exposed</DIV>
<DIV>to water. I could be wrong.</DIV>
<DIV>On the Technadyne site it mentions that the magnetic coupling
assembly dismantles easily</DIV>
<DIV>to change the bearings, so I'm wondering if these are a weak point
in the system.</DIV>

style="COLOR: black">It looks to me like Alvin's thrusters all have a 90
deg drive arrangement like yacht bow thrusters. Some of these off
the shelf units are hydraulic, but way over powered for a Delta / Gamma
sized sub. There are however, lots of little hydraulic motors out there,
a slew of them. Ive also seen drive components, reductions, etc, that
simply were not available to George. How much trouble would it be to go
hydraulic all around? </SPAN></DIV></DIV>

sufficiency. It would be nice to charge the batteries and the HP tanks
independent of a surface boat, eliminating the need to raft alongside in
swells. All this convenience means a "Tours 66" type of arrangement. But
Tours 66 weighed in at 10 tons.</SPAN></DIV></DIV>
