Stanchion vent drip for Head at base of connection directly under stanchion. Has anyone experienced this and how did you correct the issue?
I have the same problem on my boat. I've purchased Bed-It tape from MaineSail and plan to rebed the stanchion as I believe the leak is sneaking under the plate and into the boat.

Absolutely correct.
Those two vented stanchions, one port over the nav station, one starboard over the galley are the main "culprits," because they get so heavily "used" when people board the boat. Think about it.
Maine Sail's butyl tape is THE answer. Great stuff.
From the "Support Maine Sail" sticky topic:
https://marinehowto.com/bed-it-tape/
Common problem. Remove, make sure stanchion base is flat. Check deck for damage and fix with epoxy if needed. Countersink holes in deck to give more surface for butyl to seal. Re-bed with butyl tape using a backing plate on inside. Done! Don't ever push off/on stanchion while docking boat. Something else to consider while in there: change vent to 1 in. hose and move to outside of hull at rub rail forward above holding tank. Better venting for tank. Lots written here on both subjects.
Here are two links on the subject.
First, leaks at the vented stanchion base: http://c34.org/bbs/index.php/topic,7327.msg49862.html#msg49862 (http://c34.org/bbs/index.php/topic,7327.msg49862.html#msg49862)
And second, replacing the water grade vent hose with head hose and adding a second vent (reply #17)

I would suggest changing those hoses. Based on how they look, I bet they don't smell that good! :sick
Good call. I agree. It is not sanitation hose.
I bought two rolls from Maine Sail at least four years ago, most likely more.
Here's the new unused one and the smaller one after all this time.
Got you beat. I bought four rolls when I replaced my opening ports. I will be dead before I use all of mine! :?
Slightly off topic.
I noticed that the hose clamps are the old type (band thread is cut all the way through).
Having realized the issues with those types of clamps from posts here and observations on our boat, I decided to change out all of the hose clamps with the new - AWAB non perforated type.
One of the great advantages is that all sizes have the same size screw head - which fits the tool that came with the Assortment kit. Now I can remove a clamp in seconds (important when needing to clear the Raw Water Intake Thru Hull) There are still a few of the old clamps on the boat, their time is short.

Paul- what is the "tool" you speak of?
Paul : You are correct that the "cut thru" hose clamps can & will cut into the hose material on its surface.
Years ago (Mainsheet Tech Notes) I recommended the use of the "indentation threaded" hose clamps OR cut a thin piece of leather and put it between the clamp and the hose to act a "chafe guard".
A thought
Guys : When rebidding the vented stanchions :
1. Cut/drill out the old rotted decking (especially the core)
2. Refill the hole with epoxy and re-drill that hole for the vent
3. Contact Garhauer and get a vented stanchion backing plate
4. Make sure the stanchion base is FLAT
5. Use the butyl rubber to bed the stanchion vent and the bolts
6. I always used a square shank Phillips screwdriver with an adjustable wrench (on the shank) to keep it from turning
7. Replace hoses as necessary.
8. Have some patients and take your time - as leaning over the Nav table is a back breaker!!!
A few thoughts :thumb:

It's a fixed Socket on a flexible shaft on a handle.
Paul
5/16 socket or?
It's a 7mm Socket.
I haven't priced out the kit for what it contains, but it's a nice assortment for an emergency.
I can get AWABs and ABAs way cheaper than "marine" in quantity orders, but for for smaller quantities here's another source:

Steve is a good guy. And he also carries the flex handles.

Mine are 5/16. Called nut drivers. I consider them must have boat tools.
Paul's and Ken's 7mm flex wrench got me wonder, if there was a "standard" size for the grooveless clamps. "Most" of my regular clamp are 5/16 and I use a 1/4 socket set with a 5/16 socket and/or a nut driver, whichever is handy and reaches. The the fee grooveless clamps I bought recently were made in Sweden and may have 7mm head, but I didn't need/use a driver as they were within easy screwdriver reach.
Noah,
7 mm is the standard size.
You can use the metric nut driver, or any handle and a 7 mm metric socket, or a flash drive.
The downside I've found of using a socket, in tight/unusual spaces where you have the least access, there is a 99.9% chance that it will pop off the extension or socket handle. Then you're fishing to retrieve a loose socket.
The flex drive is obviously handy if you're in kind of an unusual position.
That said it's easy to fabricate your own if you have an extra, or buy a cheap 1/4 inch drive handle, and epoxy on, or superglue on, or any kind of glue on, a 7 mm socket
PS
They are "embossed" rather than "perforatef" band clamps.
Thx for the info Ken. I might try the flexible driver. My motto, much to my wife's chagrin, is "you can't have too many tools (especially if you don't know what you're doing) ..." just bought this "must have dohicky on the Internet this week! I'lll use it someday
YES YES YES!
I already have that saved in my Amazon cart. for what reason....? yah.nevah.know.com
LOL!!

Thanks for posting that link Ken.
I know that I have some large hose clamps replacements in my future - Exhaust, Bilge Pumps, Cockpit Scuppers and I only have a couple of the larger sizes left over.
Didn't mean to hijack this thread. :?
Paul
Sure Paul... well, if you have a large quantity that merits shipping them, you know who email first.

Getting back to the dripping stantion, no one has mentioned that the weld should be checked on the stantion base. I rebedded all my stantions and I found that the weld for the wire support to the base which appears to be in a hole punched in the base had a void in it, letting water that pooled on the deck when the scuppers were clogged leak into the core. Also the weld for tube the hose connects to was also a leaker. I just re-welded mine with a mig I happen to have but any weld shop can fix that in 5 minutes.
Hi Dan, Great tip. I'm rebedding all of my stantions and will look closely at the welds now. No reason to do this twice.
