[C320-list] Dry bilge?

I can't thank everybody enough for all the responses. My thoughts (Since I'm cheap) is to try the adjustment approach first. Next time we haul it probalbly re-pack it too.
If it becomes an issue I have plenty of comments to work with.
I know I have more questions coming. We need a chart plotter, Auto Helm, I want to re-do my pedestal(clean it up), some portals leak ever so slightly during driving rain.... Pleasures of boat ownership.
boat was still a great price.
Thanks,

Not that there isn't
already enough things going on in this topic...
:) My
first hand experiences
are:
PSS Shaft Seal:
I had the
older style non-vented PSS installed for 6 years. Worked
fine,
pretty dry, but burping it did let a
few drops dribble in. This could
result in
black water carbon spray line across muffler, floor and the
boards
above, so if you have a PSS, always
be sure to replace the boards before
revving
the prop after burping. You could (like Al Ahlman
discovered) end
up with a nice black line
across your aft cabin roof. The PSS set screws
don't need much bite to hold the SS ring in
place, but would bite and hold
better in
Bronze than SS if anything. Best bet is to clamp on a
doughnut
zinc to back up the SS PSS Shaft
ring. This is helpful for two reasons. 1)
in case a set screw doesn't grab well, the
bellows can't cause the ring to
creep
away over time. 2) If you need to add more pressure to the
between
the carbon block and the SS ring,
this will give you a nice reference point
and something solid to gently pry against when
making fine adjustments to
the pressure.
I also got the new vented
PSS upgrade kit shipped to me for free (but never
used it). Still have it new in the box, along
with my original PSS which is
still in fine
shape.
SS Prop
Shaft:
Upgrading the prop shaft from Bronze
to SS is recommended when you upgrade
your
prop to a heavier folding or feathering version. Other
than that, no
real need to replace the
bronze with SS (especially just for a PSS). Newer
boats all have SS from the factory anyway.
The Prop shaft is easily
removed without dropping the rudder, but you have
to remove the stuffing box/PSS AND the cutlass
bearing first in order to get
enough side to
side deflection to clear the rudder. It scrapes buy
barely
but it does with a bit of effort.
I've personally done this twice myself
(two different C320s). If I can do it, any
bozo can.
Gortex GFO Packing:
I have
been using the GFO Packing instead of the PSS for 7 years
now. The
drain hole leading under the
engine pan has a small piece of duct tape over
it so nothing drains to the bilge. The GFO
has run quiet, cool and really
100% dripless
since then. The only time I need to mop water out of that
section is when I empty the junk from my raw
water strainer and forget to
use a Ziploc
baggie around it to contain the spills.
All things being equal, I like the stability
and simplicity of the
traditional Stuffing
box with GFO more than I did the PSS. It also provides
a third point in between the coupling and the
cutlass bearing to help
prevent shaft whip
or oscillations.
With the
vented version, be sure that when revving it or moving in
reverse
that back pressure doesn't cause
the water to squirt out the top of the vent
hose. I've seen that happen first hand
also and was really surprised even
though it
was led well above the water line. I suppose it was
because it
was such a small diameter hose it
didn't take much pressure to force water
up a couple feet like a little mini fountain.
Not much water, but way more
than just a few
drops.
Cheers!

Martin - I think what was said
about the rudder was that it did not need to
be dropped and the shaft didn't have to be
removed to install the PYY shaft
seal. But
if changing out the shaft, I would imagine the rudder would
need
to be dropped. - Allan

Sliding the shaft back a ways
and removing the Shaft coupling to install the
PSS is a LOT LESS work that removing the shaft
(and then probably the
cutless bearing).
Someone on the list said that the rudder does not have to
be dropped to remove the shaft although I
really don't see how the alignment
will
allow it. Then 'they' say that the coupling should
be reground and
fitted to the new shaft.
