Hi Vincent et al, I too have not used chemicals in 10 years and get good life from the membranes. Just a back flush with product water from the tank with the presure released after each use. Danny SM 299 Ocean Pearl

Re: Sterilize the watermaker
Mark McGovern
Just to add to the knowledgebase on a related watermaker topic, when I asked Dessalator's USA rep Mark Fruehauf at Balcen (info@...) about how best to winterize my watermaker I got this reply:
"For winterizing I recommend doing a fresh water flush and then filling the High Pressure pump and membrane pressure vessels with non toxic water system antifreeze. The easiest way to do this is to use a utility pump to pump the solution into the inlet of the high pressure pump. It is also very important to make sure to blow out all fresh water from the product water lines and flow meters" -- Mark McGovern SM #440 Cara Deale, MD USA

Re: Sterilize the watermaker
Willem Kroes
In november 2017 I spoke with two Dessalator representatives on the MET's in Amsterdam. I asked them about to sterilize the membranes of my DUO 60. The answer was quite simple: It is not necessary to do that. Just after a long time of not use, turn the system on without pressure for about 40 minutes and the slowly increase pressure during 10 minutes not further than the first quarter of the meter. After that, increase pressure until the system comes to produce. I used this method now for two season starts and it works great. Chemicals in the end will destroy the system and will shorten the lifespan of the membranes, they told me.

Re: Mastervolt alternator overcharging
Joerg Esdorn
As I said above, that’s exactly the problem I found and fixed: loose connection in the voltage sensing cable for the alternator. But the latest is that the alarm came back on last night after 8 hours on shore power with the 60 A Charger. So now I’m retesting the batteries (maybe they got damaged since the last test) and looking for a loose connection in the 60A charger circuit. The fun never stops with these complicated boats .....

Regarding my previous post. My problem was much like the one described below by Bill. If wire connections are loose, when they flick the Mastercolt restart itself initializing it with a higher initial voltage charge. Hence, the additional charge

Had a related problem once. It was blamed on the Mastervolt regulator. Replaced it. Problem continued. It was later determined that wire connections had become loose after 1200 miles passage.

SM - Aft Deck Cushion
For those SM owners interested in an aft deck cushion, we purchased this three years ago. It is left outside all the time and is still in good condition. Lies flat, folds up. It fits almost perfectly. The corners just need to be trimmed. Ian & Margaret S/V Loca Lola II SM153 US East Coast

Re: Sunbed upholstery for AMEL 54 2009 / cleaning the watertank
Paul Dowd and Sharon Brown
We also had a Sunbrella cover made, and went one further having a teak frame made to measure as a base to keep it all off the deck hence allowing it to stay dry. This has worked perfectly and we have not had to remove the cushions except when leaving the boat for hurricane season.

Re: Sunbed upholstery for AMEL 54 2009 / cleaning the watertank
We do the same as Porter however we did not recover our cushions we just leave them on the deck all the time we’re on the boat great place for people like good breezes great views

We were in the same position about eight months ago – all these beautiful cushions seemed to do was take up space! However my wife, being the ingenious one, suggested we cover the cushions in a waterproof Sunbrella covering. We did so in Panama and now keep the cushions on 100% of the time even if we have the dinghy on the deck and now we have a fantastic star viewing platform at all times! Regardless of weather the cushions stay nice and clean. We often just use the Sunbrella covering itself as the functional covering of the cushions, and now rarely take the cover off as it looks so good and is so easy to clean with a spritz. I offer this to you because I was ready to get rid of what I considered a nuisance and now they’ve become one of the things we enjoy most on the boat. Best of luck! Porter.

Hi Gary, thanks for setting the record straight that it was you, not Danny who first installed the membrane flush timer. My mistake.

Re: Sterilize the watermaker
Others have posted a belief that treating the membranes can damage the metal parts. Is it Sodium Metabisulfite that is the culprit? Because of these postings, I have had someone check on Kristy once or twice a week and flush the membranes when I am gone. I believe it was Danny who put a timer on his that automatically flushed the membranes when he’s away. I’ll do that at some point...great idea.

Re: Bow Thruster lip seal
Duane,
SOG is the manufacturer (SO Giant Oil Seal Co, Taiwan - a major supplier) and I'd guess whoever got that spare erred in getting one without a totally embedded metal insert. SKF is another major manufacturer and you might try their HMS5 RG style that is nitrile covered with a single lip. Need to specify stainless steel garter spring. Try Florida Bearings or Miller Bearing near Ft Lauderdale. SOG also has a totally covered style. These are commodity items with many manufacturers. Mrs. Google will help. Cheers, Craig PS They also have a style with the garter spring encased.

Re: Bow Thruster lip seal
Mark McGovern
Duane,
I purchased my 60x80x12 oil seal for the bowthruster tunnel here: https://www.theoringstore.com/index.php?main_page=advanced_search_result&search_in_description=1&zenid=7ad56cfd50cade74b1beb97a630c80db&keyword=60X80X12TC However, the spring is made from zinc-plated carbon steel, not stainless steel as I could not find a metric seal of that size with a stainless steel garter spring. However, since you grease the seal when you install it with a waterproof grease like Super Lube or Molykote 111, I don't think that it will be an issue. I guess I will find out in ~2 years when I do my next bowthruster service. Or perhaps sooner if the springs rusts out and causes the seal to fail! By the way, https://www.theoringstore.com is also a great site to find hard to find metric o-rings. They have a huge selection of them in stock. -- Mark McGovern SM #440 Cara Deale, MD USA
