If you haven’t already read this article by @Maine Sail. It discusses the pros and cons of each type of packing material and the overall process.

The Stuffing Box (click any image to see a larger version) While digging around in some old boat parts boxes I found a stuffing box from an older sailboat. I though it would be a good time to rig it up

The material I've always used in teflon impregnated flax. I get about 6 - 8 years out of it before thinking about repacking.

BTW I run my packing gland DRY. No dripping at rest, no dripping under way. A carefully packed gland can do this.

Do We Really Need to Leak .............

............. yes, for good health, about four to five times a day is good. However, for a number of years I have been chiming in here on packing glands leaking and the fact I have run mine bone dry almost from the day I bought the boat new in late 1998 as a '99 model H310. As mentioned in...

Don't try for the dry packing gland just yet. Get familiar with the gland. IMO, one of the major causes of a badly leaking gland is a poor packing job.

Packing size is usually determined by the shaft size and the stuffing box mfg.

The GFO teflon impregnated stuff is good. I used it on my boat until I changed to a dripless shaft seal.
