dripping packing

Can someone guide me, how to eliminate the dripping between the trans and shaft connection. It is a slow dripping, but it accumulates and the rust is active all the time. I pump the water out frequently, but it will never be dry.
See attached photos.
Thanks.

Read the above thread. It is applicable to your question..

All the rust is likely caused by spray which is covered in that thread also. Cover the stuffing box to capture the spray and get what thee is left to drop into the bilge.

Should have added if questions arise then get back and can be more specific.

Good points from Lepke about dealing with the rust after controlling the spray from the stuffing box.

I will look into the Archoil for derusting myself.

Try tightening the nuts, but not too much. Old style packing w/o grease can scar the shaft.

It may need new packing. It can be changed in the water.

A grease fitting on the water side of the packing will seal even better. The water pressure will push the grease up against the packing and water working thru the packing carries the (waterproof) grease and seals small drips and prevents packing wear on the shaft. Less pressure is needed on the packing.


If you want to get rid of the rust and prep the steel for paint, try Archoil AR5100. It dissolves rust without harming good metal. Leaves a surface ready for paint. Mixes 1:16 with water. Brush, spray or soak, then pump the mix over the side dry and paint.

When the shaft is spinning that dripping turns into a spray which can travel a long way.
I suggest that most of the rusting you see in the photo is from that spray over the years.
Control that rusting after you deal with the stuffing box. Not only can the rust look unsightly but it can seriously damage parts and make disassembly of some items a destruction test of the parts and your determination.

I won't retype all what I said about the cover. If I was not clear then ask again.

Assuming that all components are in good shape, there’s no reason that you can’t have a leak free packing gland.
Modern packing materials (like GFO) don’t have to drip, like the old flax packing did.
Some people don’t like having graphite in the packing, although Ivve never seen any damage from it.
Teflon impregnated packing installed with plenty of Teflon grease works very well too.
The “spray” is from water slinging off the shaft when rotating.

Being single handed and on low budget, I need to learn a lot. I have never done this type maintenance. Are you aware of a guide, or a video I can watch, to see how is this done?
Thanks.

Just do an Internet search on replacing the packing in the gland and you will have some great uTube video to refer to. It's as easy as it looks. I routinely repack mine when I replace the cutlass bearing, which requires dropping my rudder to pull the shaft. I am on the hard every winter in storage so it's dry while I do the job, which makes life much easier.

Leoka,
I broke down so you can find my new tome below about packing boxes. Hope it helps.



Looks like there are videos available also. Not surprised.


I also was serious about covering the packing box to stop that spray. It really will cut down on the rusting. Mine was showing the same problem years ago untill I thought of the cover. The rust is still there but I stopped it from getting worse.

I will try to remember to get and post a photo or two. Not pretty.
