[C320-list] Prop shaft packing

[Cary Dennis Lowe]

Just curious. Has about done this while the boat is still in the water?  Some of my sailing friends say they have done it.  I think that it is risky.  Any advise is appreciated.

Thanks 
Dennis

For the C320 the thin locking nut must first be backed off the large packing gland nut in order to get to the packing.  It is not hand tight and requires 2 good wrenches to loosen the thin nut.  One wrench on the thin nut and the other on the packing gland.

>>> Jerry-Rather than putting up with the dripping on my hull 894 (2002), I replaced the OEM flax packing with GFO packing which is uses some form of Gortex and looks like the original packing in your boat. You will end up with basically a drip less seal by just changing out the packing. You might get a tablespoon of water under the packing gland on occasion, but for me there is no leakage most all the time when motoring or at the dock. I did this many years ago and it is the best $18 investment made on the boat.  I did the switch over on the tarmac before launch.

One of the GFO suppliers site said to measured for the size needed by unscrewing the gland nut and finding a drill size (1/4 "in my case) that snuggly fit in the space between the shaft and the stuffing box.  I bought the GFO packing from http://www.emarineinc.com.

You have to cut the packing very carefully to make a ring around the 1 inch shaft so the ends of the ring meet smoothly without any gaps.

I had a steady drip coming from the shaft recently, but tightening the nut slowed it down considerably. Will it continue to get worse quickly? Thank you all as always for sharing your expertise and experience.
