in the meantime, consider using a prop shaft collar (even a cheap hose clamp) to avoid the repeat performance (shaft disappearing in the shaft tube).

I discovered that the prop shaft had pulled out of the coupling and pulled back through the stuffing box allowing sea water to enter. We managed to push the shaft back through the stuffing box and back into the coupling, thus stopping the water flow. The boat had been pulled about a month before and the stuffing box removed, the flex hose replaced and all reinstalled with new stuffing, etc. The mechanic that had done the work suggested that pulling the shaft out of the box and then pushing it back in should not have damaged the stuffing material and, therefore, the boat doesn’t necessarily need to be pulled (again) to correct what caused the shaft to pull out. We have the older set screw type coupling, not the split coupling. The set screw appears damaged where is goes into the shaft dimple and the key is missing – hopefully not lost in the shaft tube. I’m a little concerned about possible stuffing damage and wondering if any “listers” have any advice. As always, this site is very informative and enjoyable over all the years. Thanks very much.

Subject: Re: Stus-List 29-2 stuffing box A couple of BIG slip joint (Channelock) pliers will do the trick. The infamous packing gland wrench (sink wrench) also works with one of the aforementioned pliers. https://www.amazon.com/General-Tools-190-Adjustable-Wrench/dp/B0031F02EK/ref=pd_lpo_200_lp_t_3?_encoding=UTF8&psc=1&refRID=481P75GC53T779BWMF7R I use a PTFE impregnated packing. I like conventional packing glands. I've seen a couple of failures of dripless packings. A buddy just had his boat's box re-packed by a yard. After just an hour or so of motoring, he observed some gray wax-like stuff under the packing gland. He confronted the yard manager with the evidence. seems they ran out of PTFE packing and finished with this wax-like stuff. They re-packed it for him. Here's some reading for you: http://www.pbase.com/mainecruising/stuffing_box&page=2 Dennis C.
