[C320-list] ? Add packing in the water?

[jsever1 at cox.net]

I just changed to the GFO packing and I'm impressed!! I'm not sure why anyone would want to spend the time/money on a "dripless type" since with the GFO----it's essentially dripless when adjusted properly.

Chris--where is Farmville?

FWIW, I bought my GFO packing at an industrial supply at about half the per foot cost of a marine supply.

Chris,

I have the GFO packing and mine definitely doesn't leak every minute while 
running.
It might drip 3 times the whole trip (not really sure how often it drips but 
I've watched it before for awhile and haven't seen a drip).  My stuffing box 
stays cool and does not heat up.  I think the tell tale sign if you have it 
over tightened is that the packing nut will heat up and get hot.  I had it 
too tight the first time I did it and the packing nut got uncomfortable to 
touch.

Great tips on getting out the old packing!  This is definitely the most time 
consuming task.  It took me quite awhile to get the old flax packing out.

"Adding" packing is highly discouraged, it is simply a bad practice.

Replacing the packing while in the water is a bit intimidating the first 
time, but is done salely all the time.

Cut your three rings before you remove the old packing. Overlap the ends of 
a ring on the shaft and cut through both ends at one time on the diagonal 
with a razor. This creates a perfectly fitting, self sealing ring, where the 
diagonal faces meet.

Get some rags to slow down the water and make sure your bilge pump is 
working properly.

Remove the nut and dig out the old packing by drilling in a sheetrock screw 
and pulling it out with vise grips. Use a dental pick to clean out the stray 
strands. The water that comes in around the rags is perfectly managable.

Put two rings on with the joint at 90 degrees apart, snug the nut down hand 
tight. Back off the nut again and put in the third ring at 90 degees. If you 
are using the Gore product, snug down slowly until the drip just stops. 
Start the engine and run in gear. No drips at rest and a drip every minute 
while running is the considered by many to be the ideal adjustment in 
practice. The stuffing box will stay cool and your bilge will stay dry. If 
it doesn't drip at all when running, I would worry that it was too to tight 
and and that undue friction would dammage the packing.

If you use traditional flax, 1-2 drips per minute at rest is the recommended 
rate. The water is the lubricant. Insufficient water will result in friction 
caused overheating that will destroy the packing and could result in scoring 
the shaft which would prevent proper sealing.

Have Hull #322 with original shaft packing which is near the end of it's 
adjustment but leaking a little more than recommended.  Bought the boat and 
brought it to a lake with no lift large enough to handle this size boat --  
can I back off the nut, add packing and re-seat the nut, or is this asking 
for trouble?

When I have to have the bottom re-done (Just completed last year by prior 
owner) will switch to the dripless type.

Thanks
