Sorry if this has been asked before, but is there special hose specifically made for stuffing boxes, or can something like exhaust hose or car radiator hose be used? I don't see stuffing box hoses listed in couple of the marine catalogs I have.

he must have a dripless stuffing box.,......
i have one too, it uses a small hose to cool the box i believe. i think you can use any hose rated for the heat of the cooling system. mike

Manny Heater hose works just fine
The stuffing box on Bietzpadlin was set-up also with such a tube because the cutlass bearing in the stern tube limited the flow of water to the packing There was a through hull with a tee on it and a short hose connected from that to the stuffing box. I replaced the badly worn shaft, stuffing box and hose with a PSS dripless shaft seal .

I might have the wrong name...
Hi All, The hose connects what would be the stuffing box to where the prop shaft exits the the underside of the boat. It is approximately six inches long and about an inch and half inner diameter. It is the only mechanical connection between the stuffing box and the hull. Manny

A 1980 Hunter 27 would likely have a conventional shaft log, hose and stuffing box, not a dripless type. You should be able to find replacement double reinforced hose at autoparts stores such as NAPA. If you remove and check the cross section of your existing hose it will have either one or two rows of woven reinforcing. Try to match or exceed the existing wall thickness and number of rows of reinforcing with the new hose. Make sure the inner diameter of the hose matches or is slightly smaller than the stern tube and stuffing box outer diameters for a tight fit, and use two stainless steel hose clamps an each end. Use fine wet-or-dry paper to smooth and polish the existing prop shaft. If the shaft has been scored or grooved, make the new hose a little longer or a little shorter so the stuffing box will not remain at the same wear spot. Reinstall the stuffing box with new teflon impregnated flax packing. IMHO, when a dripless stuffing box fails with a damaged bellows, its not going to be a slow leak. However, conventional flax compression stuffing boxes can be adjusted, tightened or even have the flax repacked withthe boat in the water.
shaft log hose
There is a special kind of hose used to connect a stuffings box to the shaft log. It is not just heater hose. I can't recall the manufacturer but practical sailor mentioned it a few yrs ago. I bought mine from Accurate Propeller in sayreville nj. I think it was made by Buck Algonquin.

A sturdier option --
If you have a good auto supply nearby, not Autozone or one of the other jokes of an auto parts, ask if they have hydraulic hose in the same size that you need. Most types have a braided stainless mesh made into the rubber. You will never have to worry about tearing it in half while standing on your head trying to loosen a frozen stuffing box nut. Best to have them cut the exact lenght you need unless you have a port-a-band to do it yourself. Sure it's a little overkill, but I'll take peace of mind for a few dollars more anyday. There isn't a more vulnerable spot on a boat for sinking than that tube, all other hoses should a seacock that can be closed if needed.
