Our vessels are prone to the aft shaft coupling leaking, as the shaft/shaft log are long, and the aft coupling was poorly bedded to begin with.
If you can't get the stuffing box to not leak after you put new packing in check and see if you're leaking from where the shaft log meets the stuffing box.
There's a little pick that's sold as a stuffing box packing removal tool it's really useful in getting the old packing out.
I'm not so sure that the width of the packing makes that much difference. It's the skill of the re-packer that matters most...
