You do have to pull the shafts etc to install PSS or any other packless seal.
My first set of bellows on PSS seals lasted 15 years, and were still in good shape when we replaced them. We were installing new cutlass bearings in the stern tube and strut on each side, so we sent the shafts off to be trued, did the bearings and replaced the PSS bellows. But even way past their assigned date for replacing, they were still fine. And the new ones are even sturdier.

Re: Shaft seals, dry bilge?
I had 20 years on my PSS. During the repower I switched to Tides.

Re: Shaft seals, dry bilge?
We installed Tides probably 30 years ago for the shafts and also rudders, never an issue.
Replaced them last spring with new ones just because they were getting old.
Can make a great deal on a pair of new in the box Tides seals for 2" shafts attaching to 3-1/2" shaft tubes.
Ended up having to get seals for 4" tubes because we damaged the tubes when removing the old ones.
Easiest fix was sleeving the old tubes with 4" OD fiberglass tube, didn't want to take a chance on using a reducer hose.CRICKET

Works great to stop rudder post leaks also.

Re: Shaft seals, dry bilge?
One thing to consider, any scoring or corrosion on the shaft within the stuffing box area will prevent the packing from sealing no matter how tight you make them. You need a virtual mirror perfect surface. PSS seals do not need that and are an answer for an otherwise serviceable shaft. I am also on my second set. First set lasted near 15 years and they were changed to the updated version while a bottom job and new shafts were being done.
