Re: Converting my Amel 54 to lithium batteries: what I did, what I like and what I don't like (after one year of full time live aboard use)
The Victron isolation transformer does not change frequency. It only up or down converts Voltage.
It works great! Theo s/v Paloma Amel 50 #18

Re: Victron Quattro 5000 Location
Andrew & Kate Lamb
We installed a quattro and Victron isolation transformer in 2013 in the engine room vertically where the Mastervolt 100Amp charger and the Mastervolt 30 Amp charger were. We then doubled up the two sets of cables for these devices to connect to the Victron. We had a small inverter under the chart table which had thick cabling to the batteries in place, this we replaced with the 30Amp Mastervolt charger as a backup charger. It has worked very well but we have found that it gets quite hot when charging and inverting but particularly when inverting. On occasion to the extent we received high temperature alarms in the Victron Color Control. There are fans come on in the engine room for the motor and for the genset and we have investigated but not implemented yet the option of automatically switching on one or other of these using one of the inbuilt Quattro relays when the heat is above a certain level – I believe that this is possible and I think this would be essential for extended inverting under significant loads. I think from a noise point of view that there is a significant hum from the device that may become annoying in the cabin besides the additional heat.

Hi Dean
The washer with rubber inner seal is called a Dowty washer. A good hydraulic engineering or bearing shop will carry these and be able to match up the correct size. -- Dave Ritten Auckland Prospective SM Owner

Victron Quattro 5000 Location
We are going to install a victron quattro 5000 inverter/charger and looking for advice as to the location on a super Maramu 2000.
We are looking at 2 options, . - locating it next to the nav station in the storage area on the wall that divides the companion way. This would keep the 24v cabling shorter and hopefully provide a cooler, cleaner environment. Weight on the starboard side wouldn't hurt. Question, how much noise do they make when running, compared to the fridge? - locating it in the engine room, shorter to 40v power cabling, wouldn't hear it running over the gender. Any advice would be greatly appreciated. Thanks in advance, Elaine and Michael SM251 Nebo Hobart

Hi Ameliens
I have been following with great interest your discussions, on converting to lithium . I am actively looking for a SM 2K , and it would be one of the first upgrade I would go through . There is a young guy very knowledgable who could perhaps answer some of your question, check his posts on youtube , his name is William Prowse. All the best Nick Soon to be an Amel owner 🚣♂️

Re: C-Drive vs Linecutter
Hi Olivier,
Thank you, I understand more now. The first washer does have remnants of a rubber-ring, I thought that the rubber remnants had just stuck to the first washer due to being pressured against an O-ring for six months. So it seems I need to: 1. Find a new washer with rubber-ring. Amel only? 2. Find some more thin washers to try and adjust the V groove to be vertical while the bolt is also tight. I don’t like the mastic idea much, I’d rather it sealed properly with the O - rings. I have a suspicion that the material I thought was a perished O-ring was in fact some mastic which had been put on when the V bolt was fitted. (I had too many other tasks this year and asked the technician at the marina to fit my ropecutter. I thought it was a straightforward job that didn’t have much chance of going wrong!) 3. Replace the shaft seals regardless of them showing any problem. We have 1065 hours. many thanks Dean

Re: C-Drive vs Linecutter
Beaute Olivier
Hello Dean, Bill's picture shows the original bolt and washer when no rope-cutter is installed. The washer has a built-in rubber "ring" that is necessary to get a good sealing. The problem with the V-bolt is that it must match the fixed blade of the rope-cutter, and therefore, with the original washer, the matching position of the bolt may not be the tight position of the bolt. The "trick" is to add one more washer (for instance a soft copper one, like on cars oil case), not necessarily with a rubber ring, so that the bolt can be set with the V matching the blade, and tight. If this is really too difficult to have the V-bolt matching the blade AND being tight, then, the mastic sealant will do the job. One more point about the three shaft seals: they may not leak (oil) when the boat is out of the water, but let water in when the boat is afloat, moreover if the shaft is rotating. And if there are more than 1000 hours since last service, you should think of replacing the bushing and seals now. Bon courage. Olivier

Re: C-Drive vs Linecutter
Hi, I’ve removed the V bolt completely and have drained down the oil. The attached pic shows the whole assembly. Two O-rings and two washers on the shaft. The O-ring at the top of the threaded shaft has perished. The O-ring nearest the V is slightly damaged . I’m still not exactly sure how this assembly works to ensure both a tight seal and a correct vertical alignment of the V. Maybe the real seal ends up being the mastic that Ian mentioned! Kent, I’m not so keen to change the lip seals without any clear evidence that I need to do that. I have not changed them before, and there was no problem until the ropecutter was installed in April this year. The evidence is very clear that the current problem is the Vbolt. That doesn’t mean the lip seals are not about to start leaking of course !! We launch every April and haul every Sep anyway so I’m not so concerned about that aspect. Best regards Dean A54-154

Hi Dean ,

Can’t help with the alignment of the bolt but when the Amel guy in La Rochelle did the first oil change on our SM back in 2001 he added a touch of mastic to the head of that bolt to help to seal it . I have followed that since .

Re: C-Drive vs Linecutter
Hi Dean,

How long has it been since you change the prop shaft seals? I would recommend that you go ahead and change them now. You have no way of knowing if water is getting in there as well as through the V bolt hole. If you don’t change them now, and you go back in the water to find it’s still getting water into the oil, you’ll have to haul out again. Be sure to follow the instructions on this site completely. I have been putting my seals in as several have suggested to keep water out more than to keep oil in. That’s because I’ve never lost oil and I have had water ingress a few times in the past. Since changing orientation of the seals from forward to aft so that on the first one in, the open spring side faces forward, the next two aft, I have had no water in the oil and no loss of oil for 6 years. I am overdue for a haul out by almost a year and just noticed some loss of oil. Others here, notably Bill R, strongly recommend that you follow Amel’s recommendation of orienting the seals forward, forward, then aft, so that the first two are keeping oil in and the last is keeping water out. You pays your money and takes your choice. Kent Robertson S/V Kristy SM 243

C-Drive vs Linecutter
Hi folks,
We are on the hard stand and I started the job of replacing the C-Drive lower seals since my C-Drive oil has gone a little like a chocolate milkshake. When we came ashore, I noticed a trickle of oil down the keel which implied the lower seals were leaking oil. This afternoon I removed the autoprop and the Spurs linecutter which I installed last year to get at the V-bolt in order to drain the oil. After removing these it became clear that the source of the leakage is the V-bolt, and not the C-Drive shaft seals, which do not show any form of leakage. The rubber O-seal on the V bolt appears to have perished and allowed water in and oil out of the C-Drive. I’m fairly sure the O-seal was provided by Amel when I ordered the V bolt last year. The V bolt itself was rather loose today, and I needed to rotate it an additional 35-45degrees clockwise in order to be fully tight. In this position, the V-bolt does not align with the line-cutter, so that is a problem. The solution would appear to be to fit a new seal under the V-bolt. However, it’s a concern that the previous O-seal perished in 6 months in the water. Have others found this problem, and is there a better solution than simply replacing the seal? I have a general philosophy of not fixing stuff that’s not broken, so I’m now considering leaving the shaft seals (lip seals) intact. The oil was perfect before I installed the line cutter in April, and close inspection shows no visible leakage from the shaft seals. Thought ? Dean SY Stella A54-154

Re: [Amel Yacht Owners] New size for Bow Thruster seal
Mark McGovern
Mike,
No problem. JL Mertz's Speedi-Sleeve idea is a good one too as the surface finish on the shaft is really not good enough to ensure a good seal with the oil seal. Regarding the Annapolis Boat Show, we will definitely be at the show but we are not sure if we will taking Cara or just driving. It's such a zoo around there at that time and we can't take the days off work to get there early enough to be ensured of a decent anchoring spot. Definitely let me know what the plans are as they develop! -- Mark McGovern SM #440 Cara Deale, MD USA

Hi Ian, If you speech of the Speedisleeve flag, NO I reduce the seize of the shaft with sand paper to have the exactly same diameter of the inner size of the seals, and ad a lithe "epoxy (araldit)" , the flag protect the bearing .... Bonne chance JL MERTZ CottonBay
