Juan : Most hardware stores (Lowe's/Home depot also) have a narrow adjustable plumbing wrench that you can adjust for the locking nut and the gland.  Should be under $10.

One of my favorite sources for maintenance knowledge concerning tools and techniques... (with lots of great pictures) is Mainsail and his Compass marine How To's.   :thumb: :abd:

I use something called a " Ford" wrench. Works great.

On my previous Catalina 30, I had a dripless packing system so this is the first boat that I have had to worry about the stuffing box.  I had it professionally adjusted when the boat was launched last year.  Typically does it have to be adjusted every year?  Or should I just double check that the proper number of drips/min are happening?

Thanks

ghe : Not too sure what your Catalina owners manual says, but I wouldn't want more than 3-4 drips/minute.  You tighten as necessary - probably every 10-15 hours?
 
Tighten and then run the engine in gear.  The packing gland can be warm, but not hot.  If you can't leave your hand on the gland nut, it's tooo hot/tight!!

It should be part of regular maintenance.  The "How To" are out there, in Maine Sail's website, in your manual also available right here on this webiste, and in the C34 Tech wiki, which has its own heading "STUFFING BOX."

Our boats have The best if not among the very best access to stuffing boxes on any boats I am familiar with.  No excuse not to check it regularly.

Thanks Stu. What is the size of your solid wrench?

The size of my fixed wrench is to fit the locking nut, I use the adjustable wrench for the box nut.   I don't know the size of it.  When I bought my boat in 1998, pre-internet days, I just went to the boat and measured the size of the nut.  Turns out that locking nut, at least on my boat, has two different dimensions across some of the six flats!  Go figure.  If you want to be perfectly sure, either measure what you have or buy two adjustable ones then you can't go wrong.  :clap

I use an adjustable wrench that was intended for plumbing fittings (as far as I know), nick named a "monkey" wrench.
Attached is a picture of what it looks like.  This wrench is likely79 years old and belonged to my Grandfather.  I like to keep several of his tools aboard because that guy could do anything.  It works great for touching up the stuffing box.

Additionally, my opinion and experience with the old school stuffing box is this:

I keep it wet, not dripping.  As long as my hand gets wet when I grab it, it's good. As long as it's cold when motoring, it's good.  I have only changed the flax one time in 5 seasons 4 seasons ago.  If you put it in correctly and never over tighten you have no problems.  Dripping is bad, it's a leak.
I also changed my shaft log hose which I made 1 inch longer to put the stuffing on a fresh part of the shaft. Did I need to?  I don't know, seemed like a good idea when doing the hose, cutlass bearing and prop work. I also keep a very large sponge under the stuffing box to aid in evaporation of any drips and or collection of water in the sump behind the engine.  "Works fine, lasts a long time"
