Stuffing Box

[Sailboatman]

Hi to All of you!

I have successfully eliminated almost all of the water intrusion into the boat except for the stuffing box. If at all possible i would like to stop this intrusion as well. There are mechanical dripless boxes and then there is the synthetic teflon packing. Has anyone had success with these?

Thanks for your comments.

Keep the boat in the water and the water out of the boat!!!

A friend has a teflon water seal on his yacht and is very happy with it. I can say with experience of his yacht that after over 200nm of motoring there was not a drop of water in the tray where it would accumulate if there was any leak at all. I'm thinking of that as a near future project on Bedouin, worth anything to get away from the wicking and grease gun as well as the gunk that gets built up in the gland sump.

Regards

i use the teflon packing...works great.

initially, just keep the nut loose enough to allow some dripping, then, with diesel running and in gear, slightly tighten the nut until it just stops dripping, but not more than that...just tight enough that there is no more water dripping...

all is dry under the stuffing box and shaft!

Here in the USA what brand have you purchased?

Thanks!

Or you can throw away the ancient stuffing box and install a new "dripless" seal from PYS or PYI. They are usually shown in the marine chandlery catalogs. The technology is the same as for swimming pool motor/pumps. And there is zero friction involved so all the power from the engine goes directly to the propeller.

Brenda,

before we "throw away the ancient stuffing box and install a new "dripless" seal ." ( which by the way, a dripless seal can be a real hazard if the boat is out of the water for any length of time, then returned to to the water without checking to see if the seal is still firmly in place. A good friend did not check and within a couple hours, water had come via the open seal and flooded the engine - very expensive.)

Returning to your need, have a look at Carr McMaster - pages 3400 and 2117. If properly installed , no discernable heat will be generated and without a drip.

?are you talking to me? or osirissailing?

I'm not the one talking about thowing away my stuffing box

I'd just like to know which brand of teflon packing folks have used here in the USA.

P.S. a carvel planked wood boat (like mine!) can be a real hazard if the boat is out of water for any length of time--leaks like a sieve
