Hello group I was able to take my tank out through the companion way and replace it with a new tank last year 2019 no furniture removal but awkward with lots of padding

Ken Powers SV Aquarius <ken@...>
 

I don't know how the cost could come down too much more...  I got 600AH at 24V for $3600.   The only thing I regret is not getting one more battery so I would have 900AH at 24V.

The price has come down so much that in Thailand it is more expensive to get AGM batteries than LiFePO4.

Re: Placement of Beta 60 in an Amel Maramu #replacement

Larry Salibra
 

Hi Jean-Pierre,

Keep in mind I've only used the boat 5-6 times since purchase thanks to Hong Kong's stringent operator licensing regime. When I did the sea trial with a clean hull, I saw similar result to Michael on SM251: wide open throttle gave me about 7.7 knots in flat water @ 2600 rpm. It was running bit hot though. As the propeller started getting growth, she started moving a LOT slower under engine. I hauled out a week or two ago and had a small coral reef growing on the prop and c-drive.

I've just reduced the maxprop propeller pitch from 18 degrees to 16 degrees based on the advice of the engineer that installed the Beta, which will of course reduce my top speed but also reduce load on the engine. Will see how that goes.

More power would always be nice, but it comes at a cost in terms of fuel consumption, weight, engine complexity (turbo!), and money. If I was doing the re-engine myself, I'd seriously look at the Beta 85T that Bill Rouse recommends. That said, I might still end up with the Beta 60 because I find myself leaning towards smaller engines in sailboats. The goal is to sail, not make lots of noise and burn up lots of fuel to push 16,000 kg 1 knot faster.

Hi. The Beta spunds a good option. However I repkced my tmd22 with  volvo d275 and with 1300 hpurs up it is going well. Plus points. It has significantly more torque. Even with the propellor barnacle encrusted it pulls its standard 3000 rpm. Existing gearbox bolted on. Enging mount hole  positioning was identical, fitted perfectly onto the egine bearers. All we had to do was make new forward end spacers to align the engine. Could not have been easier.

It is significantly lighter than the tmd22 and this shows in the fore aft trim. It is a turbo. But no timing belt. It is a push rod engine, not ohc. I did not make up the spacer alignment tool for this job, nor for the engine mout repacement this year. No difficulties at all. Nil vibration.

I would say that the Beta 60 has the same power as the tmd22 but lower in the rev range. My cruising revs is around 1800 and 6kn  flat out 2200 and 7.5 kn in flat calm water. 30kn wind on the nose would be 4kn

Re: Fuel Tank Leak

James Alton
 

Dennis,

   My tank had what looked like a gooey brownish tar like deposit in the lower part of the tank.  The upper parts of the tank looked pretty clean.  I found that Acetone would cut the deposits so I added some Acetone  (a liter or so) and rocked the tank back and forth.  I then removed the shut off valve and drained as much of the solvent out as possible.  Then working through the shutoff valve hole I swished around a pc. of cloth on the end of a flexible wire to help remove the deposits and soak up the remaining Acetone.  I probably repeated this process at least 10 times at which point the drainage was coming out clean and the inside of the tank that I could see looked shiny so I this method seemed to work pretty well.  I was able to dry out almost all of the Acetone using dry rags poked into the shutoff hole.  Acetone wants to evaporate quite quickly so I just left the fill, vent and shut off valve hole open for a couple of days until the Acetone smell was essentially gone based on the smell test.  I then placed a wet dry vac on the ground well away from the boat and using a long hose drew fresh air through the tank for an hour or so to be really sure that all fumes were removed before the welding.  Recognize that a wet dry vac is an ignition source so if you use this method be sure that essentially all of the fumes are gone and that you place the vacuum well away from anything important just in case!  I was confident that the Acetone was gone at that point but if something bad was going to happen I wanted it to happen away from the boat and not during the welding.

    All of the cracks were located on the forward end of the tank and the tank fits up pretty close to the bulkhead.  I used a dental mirror initially to find the cracks.  In retrospect and given that removal of the tank is really not that hard to do, I think that I could have saved time just moving the tank into the pass thru area so that I could fully inspect the tank directly.  I was actually able to inspect every surface of the tank, even the bottom.  The crack that was seeping was not very obvious,  quite fine.  I will try to attach a photo to this post.  The other cracks that I found were even less obvious.

    The welder was naturally concerned about possible fumes in the tank.  I explained the process I used to clean the tank and then he smelled the fuel fill pipe and was happy with the lack of  fumes.   I spent a few hours going over the whole tank ahead of the welding process, cleaning and polishing areas to locate all of the cracks.  I marked everything that I was able to find.  The welding only took about 2 hours and the tech welded  a lot of spots that we not leaking.  

Best of luck and if you have additional questions that I can help with let me know.

Hi James,

Thanks for your response, sorry that you had to resolve this problem before me but glad I have an alternative to cutting through the deck.  Yes, I know the tank fits in the companionway to the aft berth, I've had it out before....Some questions:

1)  Did you do the cleaning yourself or if not what type of person did you hire?
2)  How did you find the crack(s)?  Were they obvious or is there a special method? 
3)  Wasn't the welder concerned about residual fumes?
3)  How long did the process take?

Thanks

Hello Amelians,

My 1982/3 Maramu appears to have sprung a leak in the fuel tank.  This happened once before but it was just the inspection port plate that needed tightening. 

The Maramu appears to have had the deck applied after the tank was installed.  Has anyone had their fuel tank removed for repair?

What are my options?

Thanks in advance.

All that was required were two dyneema dog bones and a pair of free standing blocks at the traveler ends. The deck area around the traveler ends has a solid wood core so it's plenty strong. The system has even survived an accidental flying jibe 8-O.

Scott SV Tengah
 

Both Apple and Tesla are touting a next generation battery tech called LFP - not sure how they can claim this without the FTC intervening for false advertising. Lithium Iron Phosphate has been commercially available for almost 20 years and is what I and every other boat that has lithium is using.

One potential change is that I believe, but am not sure, that current LFP batteries (like my Victron) use 18650 cells packaged together in the box. They look like big AA batteries, so the cylinders have some dead space in between. I guess if you can design a more space efficient component, you can pack more energy into the same battery box. Maybe important on a car, but my battery compartment isn't even half full, so space is not an issue.

Re: battery balancers /A54/ Victron AGM

Hi Ulrich,
What I mean is all the cables that connect each of the batteries to the common +ve and -ve points should be the same length.
And, separately, all the connections to the balancers should be the same length.
Good luck

Dear Michael, thank you for your reaction. The super maramu uses a saildrive and the maramu a shaft drive. Also the engine room is smaller but the layout is the same. Have you also had adjustments made to the oil and fuel filter? And what kind of alternator did you connect to the engine? Thanks again and I look forward to your response.
