Hi Scott

Thanks again for the tips. The alternator will be my next step after some local testing yes. We are away from the boat down in Sydney for a week, but the Lithium install went perfectly on Tuesday, and Lauren and I are absolutely delighted!!! The 4 x 100amp 24v LifePO4 batteries fit in the 2001 SM 2000 battery compartment perfectly and we have lost at least 150kg of weight, yet to be measured...

Our 2001 SM 2000 has space for 8 house batteries plus start battery (not the enlarged 12 battery bank compartment as on later (2003+?) boats), so this awesome lithium setup would fit in even the very earliest SM's I suspect, and for the first time ever I am now pleased to have the smaller rather than the larger battery space.

Regarding the sale of our boat, we have Island Pearl II listed for sale but had not yet got around to putting her up for sale on the Amel Owners site. However, we are now seriously considering the wisdom of selling as we watch the increasing global panic related to coronavirus around the globe. We miss our sailing days already, and so we are simply not negotiable right now and may still remove her from the market depending on how world affairs turn out. She is far too nice to take a huge loss on after all the investment in upgrades we have made if there remains a chance that we will sail again.

Glad to hear you guys are soon heading over the Pacific. Best wishes for that trip and we do hope to catch up again when you reach us here on the other side.

Best Regards

Colin,

Good to hear from you! I guess you guys aren't selling Island Pearl II then? We are in San Blas now and planning to transit the canal and head to the Galapagos within a month. Slowly but surely making our way to your part of the world :)

Do you have any idea of the amp hours you're putting getting out of your solar/wind array? I am very jealous that you have that production capacity and I'd love to see numbers.

Since you're barely running the Victron 230v chargers, you don't have to worry about this, but others may want to think about it: lead batteries can only take full current at low SOC. I seem to recall around 65% SOC or so, the charging current tapers quite a bit. With LFP, the batteries will take full current up to 99% or so. That means your chargers are running at full capacity and generating lots of heat for longer periods. 

Related to that, if you haven't already, think about your 24v alternator and the regulator attached to it. I am not sure what alternator is fitted on the SM, but we have a Mastervolt 110amp which Mastervolt says is OK for the long periods of full current that LFP will require of your alternator. For good measure, I installed a temperature sensor that will instruct the Alpha Pro II regulator to taper output if the alternator gets too hot. Finally, make sure your alternator has a LFP charging profile and just as importantly, the Battery Management System (BMS) can shut down your alternator when there is an over voltage or over temperature condition in one of the cells. Note that you can have acceptable overall bank voltage but one of the 32 cells that will comprise your system may be over voltage. If your system doesn't stop charging, it could irreversibly damage that cell. 

Finally, keep in mind the Dolphin chargers don't have a LFP profile. At least the ones in the 54 did not. There's a 54 owner out there who installed 1200 (!!!!) AH of LFP and fried them in short order - I believe because he charged them using the wrong profile.

After your install, you will get a 25% boost from your already massive solar/wind array on charging because with LFP, you don't get the 25% charging inefficiency you get with lead. BTW - I've run the aft AC all night on battery/inverter and our 450 amp hour bank was more than enough.

Hope this helps.

On this issue.

Had a long conversation with Rob at Costal CLimate.  As usual, a very knowledgeable guy.

His thoughts.  Flojets are super reliable, AS long as they aren't drawing a lot of current, i.e. sucking hard against resistance, or pushing against resistance.

Often a change in pitch denotes strain, I’ve definitely been guilty of letting that go… and with in a short time, at least with my experience, the pump then fails, and off to either the junk yard, or later a take apart.  So now I’ll check amp meter if >1.2 amps check the flow and make sure the water paths are unobstructed. 

Also… they tell me the frigoboat pump controller is very unreliable, as we've noted on the forum.

So… I've ordered 4 (one extra) pump relays (https://www.coastalclimatecontrol.com/index.php/refrigeration/buy-refrigeration-products.html#!/Pump-relay-12v/p/95699277/category=25823698)

and 2 24 v pumps as it would have to wired to the 24v bus.

Just some thoughts…

Thanks Jamie. Yes I have been following this thread about alternatives and wait in anticipation! I have not heard about anyone successfully refurbishing the flowjet.

Paul, as you have probably read in another long thread about this very subject, you are not alone. Several of us are trying to come with a viable solution that we can all use to deal with these pumps.

Stay tuned if you can wait a bit. I have ordered some parts to construct a variable-speed drive brush-less motor as conceived by Oliver on Vela Nautica - waiting for the parts now. I have been in contact directly with him.

I will start a new thread if I am successful.

Hi all,

I attempted to refurbish a flowjet pump today, by simply cleaning up the diaphragms, checking the brushes and emptying a lot of carbon dust out. It then worked for about an hour ☹. I would be most grateful if someone who has had experience at this could share it with me as I now have enough of these pumps to start a second hand store!

Cheers,

Paul

Hello Stefan,

I was planning to bring the container into Annapolis, MD or the port of Baltimore.

I have a location to receive the shipment, breakbulk, and reship or allow pickup.

Do you know the amount of space your parts might need in cubic meters?

Welcome aboard Mark!

OK, we have Charles (me), Patrick, and Mark. Let's wait a couple of days to see who else wants to join us. 

 

In previous less than container shipments I have done, space was about $100-200/CBM (Cubis Meter) +documentation ($600-1000) +tariffs

Is anyone else jumping in?

I have owned my Super Maramu since she was launched in 2003.  Amel applied a hard bottom paint before launch in 2003 but since then I have only used ablative paint.  The layer is now thick and a bit uneven.  Having carefully examined the words of caution on the Amel owners group, particularly those of Joel Potter, I have looked in vain for a soda blaster to remove all the old bottom paint. I just cannot find one in Rhode Island.  The contractor recommended by my Rhode Island marina uses glass and is apparently very experienced with blasting boat bottoms. 

Last week I contacted the large Hinckley repair yard in Portsmouth, RI and it turns out that they do not have access to soda blasting either and use the same glass blasting contractor used by the full service marina where Sabbatical III is stored.  Hinckley recommends the glass blasting followed by 5 coats of epoxy (the 5 coats is their rule for European boats).  My yard has suggested 3 coats of epoxy as a water barrier.

I had been hoping for soda blasting plus a single coat of epoxy as a primer, on the assumption that the barrier coat under the gel coat would remain intact.  I did not expect that it would not be possible to find a soda blasting contractor in Rhode Island (or nearby Massachusetts) who works on boat hulls.

 

Any suggestions for me?  I feel stuck and am inclined to use glass blasting following by 3 or more coats of epoxy as a barrier coat.

Kent, it sounds like the Sena is a better option then.  I never looked at Sena when I bought my Eartec since I had experience with them before and my friend had used them for over a year without a problem.  Cheers. Joerg
