About what does it cost to have stuffing boxes repacked? And what would it cost to replace with dripless shaft seals? I don't know the shaft size, but, the engines are 210hp diesels. Not looking for an exact number, just a ball park.
Do a search on dripless shaft seals before replacing ..... these "dripless" stuffing boxes have been linked to the shaft failure and sinking of several boats.
Repacking stuffing is cheap. Probably 2 hours labor for both plus a minimum fee for coming to your boat. Packing is only 30 dollars.
Replacing with dripless will be expensive.
Haul out fee - depends on location
Purchasing dripless shaft seals - 400 dollars each
clean shaft
unbolt shaft
remove stuffing box/packing nut
clean shaft some more
install seal
install shaft
test run
Depends on the speed of your mechanic, but it will be EXPENSIVE compared to buying packing!
After owning several boats with traditional seals and now a boat with dripless.......I would never go back to the old way. It is well worth the upgrade. Anything you can do to keep salt water out of your bilge is a plus! My engine compartment looks like it just came out of the factory after 4 years and 500 hours now.....

Just replaced my stuffing box today PYI drippless . haul boat pull shaft, drop rudder for clearance, pull prop, cost about $1200 . As far as I am concerned having no water ever again in my bilge and wondering where it comes from worth every penny
I used GFO dripless shaft packing in my Silverton. It is great stuff and does not cost much more than the wax stuff. Once you get it properly adjusted, you will not need to mess with it again and it wont' leak.

This is on a boat I'm looking at buying. If the deal goes through, I'll probably just have it repacked as there will be other items I'd do before dripless seals.
In general on an older boat, if you repack one would you normally do both? Or, it it something that if it's not leaking just leave it alone?
Ditto Mr. Rosses' comments. The new packing material properly installed and adjusted leaks VERY little if any water and is bulletproof. The only real time I would consider installing dripless is in a V-drive that makes access a serious issue. I would keep the old school boxes unless you have run out of other boat things to spend good money on
stuffing boxes and dripless shaft seals
