Stuffing Box Stopped Dripping

For the past two years my stuffing box dripped about 2 drops a minute at the dock and 5 drops per minute while running under power.

Recently the box stopped dripping at the dock and drips almost nothing when running. In a year or two I had planned to put the boat on the hard and install new stuffing box and hose.

The existing box is hard to get to (V-drive) and is corroded so I did not want to tighten when it was leaking a lot. No it is basically not dripping at all, and although I know I need to adjust it to get it dripping, a little afraid I might end up in a situation where I need to to an emergency haul out. A haul out here with storage is in the $1,500 range so it is somthing I want to plan for so I can do other work like painting hull, bottom, and pulling stick to re-rig.

Any ideas why a leaky stuffing box would basically stop leaking?

Normally as the stuffing box packing wears you would need to tighten the packing nut to compensate and slow the drip. I have never tightened the nut and did have an excessive drip rate.

What would cause the drip rate to completely stop, when the nut was never tightened?

Re: Stuffing Box Stopped Dripping

My old stuffing box on my N30 would stop dripping if I didn't use it for a while. When I installed new packing used teflon imregnated packing with use plenty of teflon grease. I set it to not leak when not running. I would check the tempeature while running to make sure it did not get warm. Have you checked temp while running?

Hard to get at but there is nothing complicated about them. And it is very doable while boat is in the water. There isn't enough of a water leak when you take it apart that a bilge pump can't easilly keep up with.

Re: Stuffing Box Stopped Dripping

salt build up and corrosion make the cessation of dripping. even mine will stop almost entirely when i have spent too much time on a dock...

I felt the box and prop shaft after running for a while- nothing was hot. I will PB blast and clean up and try to loosen the box and get some drip.

Re: Stuffing Box Stopped Dripping

Mine is easy to get to, even while the boat is running. Mine drips very little and like others have said, some times really leaks very little or seems to stop.

In that condition I have put my hand (carefully - but it is very safe and handy) on the stuffing box and it is slightly warm, not a problem at all.

Re: Stuffing Box Stopped Dripping

I used an electronic laser temp sensor to check the stuffing box while under way after tightening. I do not know what the temp should be but mine was running about 95 deg in 80 deg water with a drip about every 60 to 70 seconds. No drip while not in operation. I am in fresh water.

Re: Stuffing Box Stopped Dripping

Thanks for the replys. So as long as the box/shaft is not hot I should be good, even with minimal drip. Will keep an eye on it.
Regards
