Re: Placement of Beta 60 in an Amel Maramu
#replacement
The Beta 60 has more torque than the tmd22. The hp is measured at the gearbox output

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.

Is the Beta 60 sufficient for an SM? Curious as I would like a non TC engine when I have to replace my Volvo TDM22. Kind regards, Jean-Pierre Germain, Eleuthera, SM007, NZ On 30 Dec 2020, at 14:08, Larry Salibra <larry@...> wrote:

Hi Dirk,
Sula (SM 140) also has a Beta 60 fitted by the previous owner. She has the standard 70 amp 12v insulated return alternator and the 24v 60amp insulated return secondary alternator. No adjustments were made to oil and fuel filters. Larry SM140 Sula Hong Kong |

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.

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?

Re: "Apple is examining a chemistry for the car battery called LFP, or lithium iron phosphate, for its car", that will bring the cost down for all of us
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. -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com |

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 Alan Elyse SM437 |

Amel 50, Mainsheet Bridle

When sailing upwind I generally try to center the boom for best performance which means I have to pull the traveler most of the way to windward after each tack. With the 4:1 tackle supplied as standard with the boat this can require a fair amount of effort. I see that some owners have added another set of blocks to increase the purchase and apparently Amel has even equipped their new 60 model with an electric winch for this purpose.

The two bridle lines are still attached to the traveler car so adjustments can still be made but tacking the main is now entirely hands free and the boom stays nicely centered.
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. Don Malin Amel 50, #19 - Nina

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

SM 2000 Mizzen Spreader Deck Light
Jeff Williams
Hi All,
I'm trying to replace the mizzen deck spreader light bulb (suspect it has burnt out). I've seen that people have replaced this with LED....but that's not my question. When trying to remove the bulb it looks like everything is rusted together. I can see 2 screws on each side of the bulb, but they are completely rusted and the entire housing is crumbling. It is an Aqua Signal housing.' My question is: is there a diagram for how this fixture is put together? I'm suspecting I'm going to need to keep turning and pulling the rusty parts and it is going to all come apart. Should I just pull it all out and figure out how to rebuild it after? Thanks!

Re: battery balancers /A54/ Victron AGM
Ulrich Michael Dangelmeyer
Hi Brent, THX for you interest. We do not use this cradle because it‘s to much work to install ist. It‘s a mess to pull all tubes out and to connect them just for launching the tender. We take the mizzen halyard on the powerwinch for the mainsheet, protect the topsides with some flat fenders..,and here we go. 10 minutes. After all, we take the dinghi in the arc like davits. So this cradle may be as toy to launch from the poop deck and back. We are not a German lifeboat Cruiser with seperate rescue boat to launch thru the stern. Hope this helps. This boat really got a lot of „improvements“ from the former owner. Best wishes and stay safe Ulrich Am 28.12.2020 um 20:23 schrieb Brent Cameron <brentcameron61@...>:

Re: Foredeck dinghy cradle
Hello all,
I concur with some on this issue. It reminds me of all those (mostly US) long keel yachts I used to see with jerricans of fuel and water, as well as surfboards and other junk, tied to the stanchions. Holy moly, if they ever got serious green water over the boat, all that would be lost, as well as the stanchions and the lifelines. I can't count the number of times Elyse's foredeck has been awash with the sea in tough conditions, and been so glad that everything was stored below. We are not quite in that situation now. We used to have an inflatable floor Avon which we always packed up and stowed before heading out. Now we have a Highfield RIB which clearly we cannot stow. We travel with it strapped upside down on the aft cabin roof with a cover on it and wide webbing straps to hold it in place. It's not perfect but MUCH better than having it on the foredeck I'm sure. Cheers Alan Elyse SM437 |

Re: battery balancers /A54/ Victron AGM
Thanks Paul,
that's right, AND all the +ve and -ve battery cables should be the same length, otherwise there will be voltage differences which will work against the balancing effect. Cheers Alan Elyse SM437 |

Re: Fuel Tank Leak
James Alton
Dennis,
According to the measurements I took of my seeping fuel tank and from the posts of others that have removed the Maramu fuel tank it is apparently possible to remove the fuel tank with minimal interior removal. In my case, I found some cracks in the metal/welds on the forward end of the tank, one of which was seeping. The only areas where I had cracks were at or close to the welds, the rest of the tank looked excellent. I drained, flushed and cleaned the tank with solvents. Vented to remove the solvent fumes. Then detached the tank and moved it into the center of the pass thru to the aft cabin, letting it sit on a couple wooden blocks an added some lines to keep the tank upright. The tank is awkward but really not that heavy, maybe 150 pounds? I was able to move it around in the area of the pass thru by myself with a little ingenuity. In my case, moving the tank to the middle of the pass thru fully exposed the cracks in my tank and they were welded which has so far cured the seeping that I had. Before reinstalling the tank, I replaced all of the carpet that the tank was resting on and removed the foam that had absorbed fuel. I inspected the interior of the tank where possible by the way and found no corrosion inside at all.
Best of luck,
James

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.
