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.

Re: Sterilize the watermaker

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"

Re: Mastervolt alternator overcharging

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

On Jul 3, 2019, at 2:13 PM, CW Bill Rouse <brouse@...> wrote:

Joerg,

That's what I thought when you first started having overheat alarms in your 55 battery area. The Mastervolt alternator is continuing to charge, already charged batteries, causing heat in the battery area. Pochon's suggestion to change the regulator is logical, but I am surprised that they did not check the voltage at the bank and at the regulator to ensure that they were the same.

I am not an electrician: My guess is that either the regulator settings are wrong, the regulator is defective, or there is resistance in the wire and connections between the actual battery bank and the regulator, which is lowering the voltage "seen" by the regulator and "fooling" the regulator to continue charging. 

My non-electrician suggestion: It will be a tedious process checking between both. I believe that you will find the most likely connections near and on the excite relay for the alternator. loosen each connection and use CorrosionX before retightening. Make sure that any crimp connectors are done correctly and have crimped the entire wire, replace any suspects. Check voltage often during the process so that you'll know when you have found and corrected the resistance problem.

As an alternative and temporary patch, maybe you could lower the charged voltage setting at the regulator by 2.5 volts.

Best,

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.

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.

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.

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.
