What do you think of my thru hull condition?

[moseriw]

I would change them on next haulout to marelon, not bronze. I installed new bronze ones and I do have always troubles to open/close them. (Even with proper greaseing)

On the other hand: You ask if you can brush the seacocks?
This question is telling me that you are not qualified as skipper and by this you are dangerous for yourself and others.

When you drive a car and something brakes you stop on the right side and call the professionals.

If something serious brakes on your boat and you are a two left-hander you and your mates are going down. So - before you go out - check every plug and screw on your boat and make a plan how you can repair it in emergency.

I had one that looked like that break off when I went to close it (head discharge) before setting sail on a charter boat in the BVI.
Seeing the pretty blue ocean and fish swimming under the boat through the water coming in was quite a surprise,
Wooden plug worked, charter company made a trip to the Bitter End and replaced it in the water.

That first picture is scary. When we bought the current boat, we had several that looked suspect — but not nearly that bad — and we decided to replace all of them proactively. None leaked, but two of the original mushrooms snapped off flush with the hull as we were trying to remove the hoses.

We chose to replace with the Groco flanged adapters, and I agree with Jedi and others that they’re very beefy. I also bought one of the TruDesign fittings with collar, and think it would be fine as well (and their tests show it is plenty strong). Ultimately went with Groco adapters so I could more easily replace valves and fittings using off-the-shelf chandlery hardware down the road, wherever we happen to be.

Just a little condescending aren't we? He is a brand spankin new member reaching out for advice. There are many ways to address someone here who might not be in "the know" about a boats systems.

Here let me help you out...
"Welcome to the forum. Here is what we do at our yard. ..XY and Z. I encourage you to keep asking questions like this as there are many things on a boat which could be catastrophic if not attended to quickly and properly."
You see? That's not difficult is it.

I don't get why some people have to get so damn negative in their responses.

Good on you calling this out - especially how you did it!

See people, one CAN "teach" without being an ass!

I know by self example...Being of the human condition, I have been a condescending ass myself.

These are made from a variety of components including cast iron, stainless steel and or dur-aluminum. They may be fabricated and welded or manufactured as castings. The adverse corrosive environment, specifically in seawater where the hot acidic gases and salt mixture will pursue out weakness in the components. Replacement is the best option here but you can just go for a pipe integrity check. These pipe elbows will become clogged over life with carbon and salt deposits. As these deposits, increases they may diminish the exhaust flow and gently choke the engine driving to poor functioning.

How much of your hull did they grind away to get that thru-hull situated?

cored hull or what?

[svDrifter]

I think the first thing to replace is the incompetent idiot that calls himself a "surveyor"!!!

[Bluechart]

Replace them all now.

These bronze fittings are likely from Beneteau ( who makes Jeanneau). In their genius they added zinc to the bronze (perhaps to make it flow better.....problem is that the zinc gets stripped out due to electrolysis leaving bronze fittings ready to fall apart. I was aboard a boat when this happened, we pounded in wooden plugs from the outside, and cur off the stub.

I just replaced ALL my thru hull fittings and valves. (2008 Beneteau) When I had them in my shop, I found that any with “green” (as yours show) were not shiny yellow bronze, but rose red when I explored.

Beneteau recommends replacing all items every 5 years.

I switched to TruDesign 2 years ago, and could not be happier with this product.

1. Get wooden plugs at every thru hull fitting now.
2. Get real Silicon Bronze fittings, do not get from Beneteau or Jeanneau. Or TruDesign.
3. Get the boat out of the water, on the hard and get these replaced now.
4. Get a refund from the surveyor. Or if no refund- report him/her to the association you will find in the survey report.

Looks like an X-ray of my liver.
Replace & all when you haul out- and upsize the galley sink drain while you’re at it- helps eliminate clogging from scraps, etc.

With all due respect, I'm fairly certain that these are NOT "bronze" at all, but straight off the plumbing shelf at the corner hardware store!

I have recently purchased a Jeanneau SO 42DS which I'm very happy with. Being new to boats I'm struggling to work out if my thru hulls are a concern. I have heard thru hulls are a general weakness of these boats so I would be very happy to hear what more experienced people think.

I did have the boat surveyed and pointed the surveyor towards them and he said their condition was fine. I asked how you can tell if there is imminent failure and he said they would start to weep first - does that sounds reasonable?

Thanks in advance.

Caveman:

That raw water intake valve is an accident waiting to happen. It doesn't look like the crappy OEM valve from Jeanneau but failing just the same. Photo is a dead ringer for the valve on my 2007 42DS. The Jeanneau faulty metallurgy fails from the inside out and was paper thin at failure. It snapped off from hand pressure the night before a 1400 nm trip. Replaced it with another Jeanneau part and it corroded thru in three years. I just replaced all my major thruhulls (heads, engine, genset, A/C raw water) with Trudesign composite. One exception was a Forespar part #931274 for the engine raw water (your photo). This Marlon valve has a built-in garden hose fitting on top and three position handle for easy engine flush or winterizing. Both Trudesign and Forespar are nicely engineered and easy to install. Trudesign even has an add-on collar that eliminated a backing plate if necessary.

The commanding officer of a navy vessel is not a USCG licensed individual but is called captain due to him being the boss on the boat.
So you really need to loose the condescending attitude
