We just had ours removed. The mechanic used a pipe wrench to take it out. The fitting is not tapered, so you will have to inch it all the way out. It distroyed the fitting, but we opted to have a muffler made out of fiberglass anyway, so I didn’t care. If you decide to buy the Jeanneau muffler, figure in the price of the fitting. Interested in getting details of who and how much to fabricate in grp.

Thank you for your reply on removing the pipe from the muffler. Did he distort the pipe or the muffler itself?

The pipe wrench wrecked only the fitting, and didn’t damage the muffler. But when the muffler was pulled out, there were rust stains on almost every seam. Guess there were about a dozen pinhole leaks. And the aft seam was almost completely rusted through. So we opted to replace the muffler. The new muffler was constructed from G10 fiberglass, which is heat resistant to 285F (140C). Took two guys about two hours to remove, and about three hours over two days to install. The split was needed as the top fitting needs to be epoxied in place, and needs a day to cure.
I still don’t have the bill. The fiberglass guy is so busy, he hasn’t done the invoice yet. The only estimate I got was don’t worry, it’ll be less than the cost of the replacement from Jeanneau.

If it helps I used a drill to dimple the screw fitting flange at 20mm intervals and then a pin punch and heavy hammer to unscrew the fitting. A slow, tedious job but the fitting was reusable.

And we finally got the cost of the muffler. For just the muffler and fitting, it was $2700. Cheaper than buying the Jeanneau part, and it should outlast the boat. The G10 fiberglass material accounted for almost half the price, and the guy who built it was one of the best fiberglass guys around. His name was the first one that came up when we went looking for someone to build the muffler. At least it is all done and we shouldn’t have an issue again.
We did look at Vetus and other mufflers and could not find a suitable replacement. The problem we were having was finding a location for anything else. We tried locating a Vetus between the water and fuel tanks under the aft berths. The problem with this was the muffler inlet was about 8 inches (20 cm) above the exhaust hose. This created a water trap between the engine and muffler. The closest we could get the muffler in, with the inlet level to the exhaust hose was just forward of the steering quadrant. That was too far from the engine. So this option made the most sense to us.
If anyone needs it, I do have the diagram of the muffler, given to me by Jeanneau. The muffler is the same unit used in the 43DS through the 54DS, from about 2002 to 2006. Just PM me an email address and I’ll send it.

Excellent work -- seems like quite a bit of "mods" there to get it to fit , but you got it done. I am still trying to figure out where the original stainless steel water-lift muffler is in relation to this . I will be at my boat next week to try and find it.

I have been following this thread with interest since commissioning Pyrat in 2011 with the thought that someday I may need to do that. It appears someday is here!
With the help of this thread, I have managed to extricate the W/L muffler from it’s position. It does appear that the instructions posted by Tafika II are not exactly the same for the Mk II but I was able to get enough hints to help. Also, my spouts are welded in place.
So far, I have managed to slide the muffler back as far as the vertical panel for the pedestal berth. However there is insufficient space available to lift it up and out, given the length of the stringer forward. I am contemplating turning the unit 90° to starboard. My expectation is that I should then be able to slide it under the vertical panel. But given the length, will there be sufficient room before the hull starts rising? However, I will need to remove the non standard hose barb from the sail drive thru hull. I am in the water so that would need to be accomplished with caution. This plan is complicated by the fact that I have my inverter mounted on a platform aft of the vertical panel, necessitating it’s removal. It appears the only option I can see is to cut out a section of the vertical panel?
How have others removed their unit?
I have considered replacement with other than OEM. My main concern with the available options is capacity. Why on earth would Jeanneau install this monstrosity with 18L(?) capacity when most of the options are 10L? Is this size acceptable?

Hi there
I am surprised that your muffler was not in the port base of the engine
Size wise I had the same worries when I was replacing mine and the only outcome was that the amount of sea water remaining in the hose might be more than the capacity of that muffler, hence the water might reach the engine. This is something that I want to test but I need to allocate the time
Now, to remove the muffler you have 2 options, you either remove the fuel tank (I'll be doing this in the coming months and taking the opportunity to clean that part of the bilge) Or you cut it as a chunk of cheese as you are sliding it back.
Cheers

I am now in this same position of dealing with the muffler. This thread is wonderful and has helped immensely with thinking about and finding the issue. my boat is a SO49DS, I would appreciate any guidance.. thanks

I know this thread goes back a few years but, like rxc, i am concerned that my muffler might be about to fail. What puzzles me, and Dave/dknebes did not answer RXC's question, is that Dave talked about removing the fuel tank to get at the muffler. I think both Andreshs1 and Tom/tsenator have 2002 models so i guess likely to be the same config as described by Dave/dknebes. My 43ds is 2004 (and that of rxc is 2003) and certainly on my 2004 model Jeanneau installed the fuel tank mid way along the saloon under the floor. Between the chart table and the floor-level cupboard under the saloon seating. There is most definitely no muffler under my fuel tank, it is firmly seated on the hull with no space either side nor underneath.
Is it possible that 2003 & 20004 models have a different setup? Are our mufflers on the 2004 (and maybe the 2003?) plastic instead of SS? While it is very much hidden underneath i think my muffler is low down behind the engine on port side. The exhaust outlet to sea is on the starboard aft quarter. I would be most grateful if one of you who might have replaced the muffler on a 2003 or 2004 model could help clarify. Some pics would be useful and source of the parts & prices as well.
Am not on my boat right now but from all the horror stories i read about the Jeanneau mufflers this is something i wish to check when i am next on my boat (Covid regs permitting.....) Andrew

Hi Andrew
The muffler was never under the fuel tank, but we needed to remove the fuel tank to slide it out
The muffler is under the starboard side engine support base
You can see it from the back of the engine room following the exhaust

Certainly on the 45DS both stainless and plastic were used. Using photos from this thread and others as well as the Facebook group I put together a range of "fixes" that inventive owners have developed for many models. www.jeanneau-owners.com/hintsandtips/exhaustmuffler.html

I just found this thread again, after 7 years, and I want to thank andre for the photos. I looked at my earlier comments, and I have to admit that I did not appreciate that Jeanneau had buried a large SS structure in the engine stringer. I realized this was the case about 2 years ago, when I had to replace the gasket on the fuel filler hose connection into the fuel tank, which required pumping the fuel tank dry and opening it up. I have had the muffler replacement project ticking over in my head for a while, along with replacement of the aft holding tank and the two holding tank discharge valves/thruhulls.
Good to see that it is possible, at a reasonable price. Once again, thanks for the photos and the info about the replacement.

Hi all
on the topic of the muffler, and with the intention to reduce further the engine sound on the cockpit. Has anyone installed a second muffler between the one next to the engine and the exhaust thru-hull?
Cheers

Cayoloco,
We are in the processing of upgrading our battery bank and swapping the standard shore charger to a Victron 2k Charger inverter.
We hope to run our single AC unit via the inverter when the engine is running. Ie; as we motor into harbours we shall close the boat up, put on the AC and hopefully take the sting out of the interior heat by the time we are moored.
Our AC users 800 watts but no doubt there will be a spike at start up. Hopefully the Victron can handle this otherwise it will be a soft start added to the AC

Hi Alenka,
Can you share Victron 2K charger/inverter model and installation location? We need to do the same thing sometime over the winter.
Thanks, Brian

Hi Wheelsucker,
As per recommendations on another thread somewhere on here we are increasing our battery bank to 4 Gell batteries and using the space in front of the batteries for a smaller start battery.
Don't know where we are going to fit the charger inverter yet* - just waiting for it to arrive; And swapping the existing MPPT for a Victron to keep everything from the same manufacturer.
Will post pics when I can.
*(hopefully it will go in the space of the old charger, under the port seat in the aft cabin)

After searching online and this board it seems like this is a common problem. My wife and I have had this boat 4 1/2 months now and have added 6kw Northern lights, 3000 watt inverter/charger, 6 group 31 AGMS, 65lb Mantus anchor, new Racor filter system, battery monitoring and then water in the bilge comes along. Interesting that a stainless muffler starts to rust then starts leaking. Jeanneau obviously has a design flaw and I would imagine more and more people will develop this problem. I have to guess it is a high carbon stainless that is rusting. I have the fuel tank drained for removal today and had great difficulty removing the flange/3" pipe before sliding the muffler out. I called the Jeanneau parts guy 2 days ago to find out the cost of a new one but nothing yet. I am a bit concerned about this failing 10 years down the road if we still have the boat, so I am first going to see what it would cost to fabricate a new one out of a better grade of stainless. What have some of the others done on this problem? I saw one member putting in a Volvo muffler but am concerned about the height and distance from the engine and the possibility of getting water running back into the engine, I also thought of getting one made out of fiberglass but am not sure how they would put threads on the tank so you could screw in the flange after it was slid under the engine beds. I will advise as this project proceeds . I have to say my wife and I love this boat and just have to sort out these few issues. Dave & Monica Exit Strategy Update, I have the muffler out and it was not for the faint of heart, a very difficult job. The muffler is rusted all the way through on the end and i easily poked my screw driver through, the rest is actually very clean except for another weld that I found leaking after I filled with water. I would advise anyone else with this type of muffler to check the end visible in the front of the engine bed, if it has rust it is ready to fail. Jeanneau just said its out of warranty but this is a bad design and a defective part that they should cover in my opinion. View Attachment

hi
can any of 43DS captains explain, how to change muffler and where can I get a new one (Jeanneau parts or do I have to do it on my own?)
thanks
