recent experience
I just experienced this situation myself. Jeff Morrison's reply mirrored my experience replacing the stuffing to a T. It can be done in the water! Although anxiety producing, the water coming in was not as much as you would fear. In my case, perhaps just under a gallon a minute, easily handled by the bilge pump. It may even be advantagous to replace the packing in the water as the water pressure may help dislodge the old packing out. I agree strongly with Jeff on several points. The hardest part is getting the old stuffing out. Have a variety of tools ready to be used, ie bent fish hooks, etc. Having a second person there to help is immensly reassuring, provided they are of a calm personality and not prone to panic. I personally would have more than 3 rings of stuffing precut, you just never know. I agree that closing the stuffing box after each individual ring has been placed is helpful. I used the gfo packing and the leaking ceased just with hand tightening, yet i could easily turn the shaft by hand. Since i replaced it 2 weeks ago the bilge has been like a desert. jdn
