Re-Packing A Traditional Stuffing Box Photo Gallery by Compass Marine at pbase.com

It looks like the small nut is loosened by turning it clockwise which is not the way you usually loosen things.
The big nut is turned clockwise to tighten then the small nut is turned counter clockwise to tighten.
You need two wrenches on on each nut at a time so you don't torque the hose.

I found out why the flange is turning into a ball of rust.... The hot water tank relief valve is directly above it and apparently venting off a lot. I can 'fix' it with a hose direct to the bilge but I'm guessing this should not be venting often so I may have a problem with the relief valve or temperature regulation. Oh the joys.....

Re: Does anyone recognize this shaft seal?

Hello, It is obvious to me that you have a Serious problem with electrolysis. When you repair your packing gland I would suggest that you check all your through hull connections and make sure they are bonded together with either a copper strap or wire connected to the ground plate and the engine ground. You can accomplish this task with stainless steel clamps making sure to clean each fitting completely before connections are made. This will allow your replacement of packing to last for a very long time. The stainless steel shaft and bronze and steel on your couplings are dissimilar metals creating electrolysis. Yet if they are all bonded together it will wear on your zinks as the sacrificial metal.That's the reason for having zink anodes to be replaced as needed. Check your stainless steel shaft for Pitting under your packing gland simply by un clamping the hose and sliding the Gland forward towards the engine, at that point you should be able to see the condition of your shaft. This is best done while the boat is out of water. Captg

Re: Does anyone recognize this shaft seal?

You do want your stuffing box (packing gland) to drip when you are moving under power, and this will sometimes result in it dripping when not under power as well. The standard is a couple drips per minute. The purpose is to keep the shaft lubricated and cool where it goes through the hull so even if it does drip when not under power it is better than not dripping when under power.

After you tighten it as was correctly described earlier, take the boat out preferably with someone else so they can hold the tiller and go down to check the drip and make sure that after running for a while the stuffing box is cool to the touch, more or less the same temp as the water that your are floating in. If it gets too hot then you wear out your shaft have a big leak have to buy a shaft... you know where that goes.

As for letting it drip at its current rate, I wouldn't advise it. I had the same problem and an auto bilge so I said I will let it drip, it is fine. Long story short, pump malfunctioned I wasn't down for 2 weekends and when I came down the bilge cover was floating and had I left it another week I would have been replacing wood in the interior. Got lucky!

Listen to Bones.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
