I had the same problem with my shaft being worn by enthusiastic over tightening (ex hire boat). Fortunately I was able to turn the shaft end over and consequently move the worn part (see Windmills And Wine thread at Dunkirk).
I fitted a Deep Sea Seal and we're now drip free with no wear on the shaft, I had one on my previous boat and never had any problems for years.
I hope this is helpful.

I cleaned up my shaft at a prior haul out when I replaced the strut bushings.
Still using the same packing.
A prior owner had a gigantic 3 foot pipe wrench laying in the bilge. He said he used that to tighten the gland nut. When I got the boat, water was spraying out. The guy was clueless regarding mechanical things. Did he know about the locking nut? Who knows.

GFO doesnt have to drip. Simple job just remove those two nuts slid off the packing plug ring pick out all the old packing clean everything with WD40 repack as Hop car said. Three or four rings what ever will fit. Not spiral but rings.

For folks with a scored or corroded shaft a longer or shorter hose will put the packing in a new spot.

Thanks everyone for the tips. I was able to take out the four rings on each shaft. Once I sprayed them with WD40, and used the previously referenced tool they came out easily. I have the GFO coming in the mail. Thanks for the tool tip.

I want to change the 12 yr old hose clamps. I currently have "Ideal Flex Gear HD, # 462" . I am having a challenge in finding them on line. kscdirect.com has them back ordered and I can't seem to find them anywhere else. Amazon has a Breeze product but not the right size.

Does anyone know where to find an adequate replacement item? I need eight of them. I want to change them before we splash in about a month.

Thanks,

JimL

Those clamps look similar to the clamps the trucking industry use?

Constant torque, little spring under the tightening nut?

Try the local NAPA or heavy truck supply house?

I recommend you have the yard do this while you are on the hard. I had a mechanical seal fail while dockside, and was only alerted when the bilge pump started to run constantly. Very scary to wake up to.

This Amazon Search!

Or, a Cummins Marine dealer, the white monsters are covered with them!

Would these constant tension clamps work for you?

For my two penn'orth I'd go Stainless Steel hose clamps as the trucking industry use zinc plated in many applications.
Stainless is painless.

Thanks for the tips. I found this correct clamp at Napa and thanks to Parks at Hopkins-Carter Marine Supply and Fishing Tackle. There are only a few sources for these clamps, so plan ahead!

Hi All,

I replaced the packing material with GTU. I found out that 24" per shaft was just short of 4 rings, so I have ordered another package.

I also found the clamps for the prop shaft hose. They are not a common item. Thanks Parks and Sdoney717.

The rudder glands look ok and I'll keep an eye on them. They may need to be replaced in another year or two. There is evidence of some seepage. They are not like the prop shafts. I'll need to take a pic and figure it out.

Thanks everyone.

Hi All,

Boating is around the corner for us in the North. Last season I replace my stuffing box with the GTU stuffing product. I should have used another ring moving it to 5 rings from 4. The starboard stuffing box is fine, but still drips more at rest that I'd like. The port stuffing box drips more at rest and has leached out a sort of textured sediment that appears to be teflon type stuff. if you could put it in your fingers, it would be like wet powder.

I'm thinking of moving to GFO for the material for the shaft log. Ultimately, I'd like to go for a dripless shaft, but that is years away.

Any recommendations?

As alway, I thank you for your recommendations,

JimL

A lot of people have tried using the same packing normally used in pumps. It is impregnated with graphite and it will DESTROY your shaft. Don't use graphite impregnated packing!

It is an old thread now but I would also have tossed those old nyloc nuts and used a normal nut and a locknut.

I think this is a good answer. And I can also endorse GFO packing...there's no need to engineer in drips in 2018. Get the yard to do it 1st time while you watch....and check they remove ALL the old packing including the bottom ring that will no longer look like packing but can appear to be part of the surrounding bronze housing. As it is likely this will be the 1st time since launch the whole setup has been inspected, I'd take the opportunity to replace the hose and inspect the shaft where it runs through the packing; this is where crevice corrosion is most likely to be found. And sliding the shaft back makes it easier to remove the packing and clean up the whole box generally.

GFO does indeed contain graphite, but is a very different packing than graphite pump packing.
I believe the difference is the GFO marine shaft packing uses graphite particles in PTFE with Goretex fibers.
The Gore fibers alone or the graphite without the Teflon would be a disaster, but he combination is a modern miracle!
Silicone grease smeared liberally on everything during installation helps insure ease of install and fills any voids that might hold seawater.
Fresh water flushing can help, especially at layup time.

Just remember graphite is the top of the list for reactivity and will eat every other metal placed adjacent to it.

Xsbank, so if graphite is on the top for reactivity, and a dripless system is not in the cards, what are your recommendation for a stuffing box material? Should I revert to the original flax?

As I said previously, I'm not sure GTO worked for me as one prop seal had a lot of "fines" in the drop basin collection bowel, while the other shaft performed within expectations. I am looking to change them both to something more reliable while still on the hard.

GFO does contain some graphite, but it is perfectly safe to use.
XSbank was referring to graphite pump packing, which is the WRONG material to use on your boats shaft.
GFO comes highly recommended, and won’t harm your equipment.
That said, I flush the entire raw water system including shaft gland with fresh water after every trip.
Drip.ess systems often use a graphite disc too.
