Re: tb/AMEL 54 electric water pump/

 

Arno, I agree completely. I watched this video about 2 years ago. This video is a perfect example of what NOT to do and a perfect example of how to compare an Amel-designed system to another. Amel designs things that are difficult to operate incorrectly. I call this child-proof design. The complicated system shown in this video has the risk of many built-in possible operation issues and operator failures, like the failure to set a valve correctly or the failure of dozens of added parts.

Obviously, the owner of the boat enjoys over-complicating things and enjoys tinkering with his boat and its systems. My comments are not to criticize him, but rather to use what he has done as an example of what not to do. Can you imagine if you just bought this boat from him? Would you completely understand the operation of what he has installed and the risks with setting a valve wrong and the risks with failure? I am sure that this is not the first thing he has modified.

One-way valve installed before the seawater filter:

Wow!!!

More, also notice the flow sensor is orientated so that debris falls into the sensor

This was probably an afterthought because it wasn't there when he first showed the completed project. 
He just added further complications and increased the risk of something going wrong.

I urge all Amel owners to restrain themselves from this type of overcomplication. Especially because if you simply change the Onan impeller every 250 hours and do it correctly with an OEM impeller, you will not experience losing impeller parts into the heat exchanger. Also, the heat exchanger should probably be removed and completely cleaned every 1500 hours.

I’m not sure how long a normal impeller will last but if it lasts a boating season or an oil-replacement interval I don’t see the advantage of this solution. A spare impeller is cheaper then a spare pump and even the Sharewood raw water pump is not that expensive to keep as a spare.

Ken,

How are the starting batteries holding up in the engine compartment?
I had the replace all batteries after less than two years. One reason was the lack of care and bad monitoring from the yard (I assume that they were left discharged for too long). The other reason was the high temperature in the engine compartment. I was told that batteries do not like high temperatures. So we moved them out. We'll see how things evolve now.

I would recommend either make a wrench or buy the one available from Amel.

Hi Teun,

We’ve talked about this before. I just don’t get it. What is the added value of this setup? Why is the existing impeller pump not sufficient for feeding cooling water? 95% of the Amels (I’m guessing) has this set up and seem to be fine with it. Unless you remove the impeller pump completely, it will still be a source of (shaft) leakage at some point. The only thing I can imagine is if you use the genset frequently at continuous high loads you may want to improve the flow. In all honesty I would then enlarge the heat exchanger as the mickey-mouse version that is standard part of the genset seems to leave quite some room for improvement.
Adding another pump seems just to complicate things.

Just my two cents,

Arno

I would think that the reason for the centrifugal pump is to eliminate the impeller changing on the Onan.
The impellers don't last very long in most cases. That's my experience also.
I have a March pump which I will install when I run out of stock of impellers, but I will completely bypass the impeller pump and feed directly into the heat exchanger.
I first saw the March pump on Amelit with the previous owner.

Re: New LiFePO4 Batteries for Aquarius

A couple points regarding the starter battery:
1) Ken - could you post some pictures of you starter battery install in the engine room? 
2) Regarding starter battery failure - we have a 12v battery charger, so unless you have a catastrophic failure (internal short), you will often have signs that it is weakening. Our first sign was difficulty starting the genset, but the battery charger then gave it a sufficient boost to get through the genset starting sequence until we could purchase a replacement.

Re: New LiFePO4 Batteries for Aquarius

Ken,

Very much appreciate the lead.  

Shipping/Customs/trans ship/etc to the US is $1267.  So, all in door-to-door we would be at $5512 for a set of 3.  I have been looking at Victron LiFePO4's.  The Victron set was quoted at $11k on the east coast of the US (full 8-battery set replacement....yeah I know that is capacity overkill). It appears to be great value for money for the batteries if the construction is up to snuff.

I asked Joey for additional data to satisfy my nerd brain before I will pull the trigger: internal construction layout, wire gauges, solder/mech connections, separation and damping, venting, low temp disconnect, and BMS make/model.  Will share when he gets back to me.

Hi Ken,

I understand you are thinking about a third set of 300AH/24V .

Is it possible to have two sets of 450AH/24V instead? Or do you think that is not recommendable?

Eric onboard Kimberlite will be sailing from Sint Maarten to New York on June 20th. 

This would be a good opportunity to bring parts, especially bulky or heavy ones like sails, winches, etc. 


Let me know interested.  Not everything is listed on:  http://supermaramu2000.com/parts_for_sale/index.html

Hi Jose,

Great solution and explanation. Thank you for sharing.
I hope to buy my SM2K soonest this year and I am studying as such all sysyems in preparation of a refit. Solar and LiFePo4 baterries is the hart of the power(s) systems and in my view the only way into the future.

could you share a diagram of the wiring system with all the equipment you installed (inverters, batteries, solar, alternators, generator,shore power, relays etc) 
A diagram makes it so much more clear than text,

Thank you and happy sailing
