Grease for oil seals

Patrick McAneny
 

I am going in install three new oils seals and a new wear bushing . I have for years been using wheel bearing grease,I have never had any leaks. However, I saw a mention of silicone grease being used. Would that be better ,is this what is supposed to be used?

Thanks,

Pat

Predict Wind

Patrick McAneny
 

I bought Predict Wind a few months ago and  a Iridium Go to download offshore. I found it to under report winds with TS Gordon by a large margin,like 50%. Now with the Hurricane Florence and sustained winds of Cat4 140 mph reported for the last two days ,Predict Wind is showing from 68mph on PWG to 102 mph on GFS. Since this is a well reported storm I don't understand the under reported wind speed . Is PW generally this far off, can it be relied on? I asked PW about this and basically they said , that their models are"not geared to predicting hurricanes." I do not understand this explanation , a hurricane is simply a low pressure system, their models are not geared to predict low pressure systems ? I have been looking at their models and comparing them with known conditions. So far it is not reassuring , has it been found to be reliable ?

Thanks,

Pat

Not only free 🍺 24/7 (great with your morning shower) but free happy hours 6-9 M-W-F. For what more could sailors ask?
Former Navy hurricane hole, too,

We can have a mini-Amel rendezvous to make up for it being unlikely to make it to St. Michaels by boat (may have to drive).

Hello Amel Friends,

With mixed feelings about selling, we recently asked you to identify anyone you knew who might be interested in buying Rascal.  Happily, we received a number of inquiries and had a contract soon thereafter. 

However, we couldn’t come to agreement on price and the buyer reneged.  So we are happy to keep sailing until a serious buyer comes along—perhaps referred to us by one of you.  Updated details about Rascal can be seen here.  

Rascal is berthed at the Charleston City Marina, SC though we are likely to leave tomorrow morning to flee the wrath of Hurricane Florence!

Rick, Sorry about your deal, but get out of there. If you have not seen the latest forecast, they are predicting it to turn SW , maybe going S along coast before turning inland .

Rick, I meant to add that it is good that you are on the south side of the storm ,and so you should not have anywhere near tidal surge or wind that they will just further north. I hope it stays north of you , looks like it will. 
Stay Safe,
Pat

Engine alignment process help please.

Porter McRoberts
 

Gentlemen and Ladies.  

I am hoping one or more of you might have information about how to put an engine and drivetrain in alignment, once it is out of alignment.

As many of you may know we now have a new long block.  Despite my pleading with the mechanics to mark all existing locations for replacement of hardware, they did not do so, and so now we have some good amount of vibration.  Shrouds and stays vibrate, along with the handrail.    

I believe the engine and drive train to be out of alignment.  

i have the instructions: to e followed from the beginning- prior to engine removal, but not with how to estalish alignment de novo, without the existing marks.  I have not heard back from Amel re how they install initially, and the “mechanics” are returning to the boat on Thursday.  

Might anyone have thoughts, comments or instructions?

All would be greatly appreciated.

Re: [Amel Yacht Owners] What are the to do’s before and after haulot of a SM2K

greatketch@...
 

I have never actually calibrated it.  With all the variables, I just treat it as a "qualitative" measure of salt content. 

I grab a sample from flow meter tap on the watermaker panel and as long as that is less than 400 ppm, I am happy.  I have a handheld meter I use for that check.

I include on my monthly maintenance checklist to pull the sensor and clean/inspect the pins.  If there is any significant visual corrosion, they get polished.  Any deep pitting, and they get replaced.

Some additional thoughts around the Dessalator TDS sensor...  We have one of the older boats where the sensor actually does control the reject valve. I do not know how to tell which type of circuit board you might have on your boat. And while it works... as Bill Rouse says it is not to be trusted, or at least not without regular verification.


The TDS sensor consists of a rubber plug with two stainless steel pins into the water flow.  The resistance between those pins is measured.  High resistance is "good" water and low resistance is "bad" water.  So far so good--in theory. 

The problem is that the system is terribly "un-robust," and almost everything that can go wrong with it makes you think that "bad" water is really "good."

The first problem is that the stainless pins corrode over time.  The layer of corrosion on the pins increases the measured resistance making "bad" water look like "good" water to the system.  This was my first clue about the corrosion issues with this sensor. Our reject valve began accepting water immediately on starting the pump, which was a change in behavior, and not what I'd expect. If your system is accepting water from the membranes as soon as you turn it on, check the sensor for corrosion.

Second problem:  The pins can become disconnected.  The system dose not seem to recognize this and just assumes that the infinite resistance it sees means that the water is perfect...

Third problem:  The measured resistance will actually vary depending on how much of the pins are exposed in the water.  The design of the sensor is literally two 3mm SS pins stuck in a rubber plug.  There is nothing that fixes their position.  Deeper immersion of the pins means the water would have to have lower TDS to trigger the switch.

So... Operational lesson always check your water with another meter.

Another lesson, If the pins on the probe corrode, the probe (the rubber plug and two pins) can be purchased from Dessalator US distributers for about US$75. You can also reuse the rubber plug, get 3mm OD stainless rod, cut it to length, and make your own new pins for a few pennies each.
