Re: Opacmare - replacing sensor
Actually the sensors are Hall-effect sensors.
Those plastic covers on your passerelle are non-existent on ours. The big problem is that the water gets to the top of the rotational actuator where the “seam” is between the stationary part and the rotating part. In our case after replacement of the actuator I put an stainless disc on top of the actuator and put a huge load of lanolite grease between the actuator and disc. I also drilled some drain holes in the frame that screws on top of the actuator to avoid standing water and to make sure it drains away from the actuator. Regards, Arno SV Luna, A54-121 |

AMFA bilge pump spare part
ianjenkins1946 <ianjudyjenkins@hotmail.com>
I have the original AMFA bilge pump. For the second time in 21 years ( I make no complaint--would that everything lasted that long ) the plastic cogged wheel that connects the motor to the pump has broken.
I have emailed Reya, the French group that now owns A. M.F.A. in the hope that they still carry spares. My recollection from last time is that they sell you the motor attached to the wheel.
Not cheap, but a sound of great comfort when it works.
Has anyone recently had to get this spare part ?

There are several ways to remove the companion way slide. I am not familiar with the details of the way an SN is assembled, all my comments apply to the SM.

Re: Opacmare - replacing sensor
Wolfgang Weber
Hello Arno , these sensors are induction nearing sensors from Pepperl and Fuchs. They have all datasheets on the Webside available in many languages. My up/down sensor was labeled NBB4-12GM30-E2 . Switching distance is 4 mm , so I adjusted them very near to the sensing metal which gives the right position to turn the gangway in to resting position. As you mentioned the big problem for the gangway is saltwater between the stainless passarelle and the rotating actuator. You see on my picture that I cut the white nylon-cover and pressed grease in each screw-hole . For this procedure all screws had to be loosened for 3 mm and fill one screw-hole with WD40 and later grease, fasten the screw and by the time grease will come out at the borders. I hope this will keep me away from buying a new rotating part for 6k. The opacmare company was no help ! Now answer a lot of contacts by email. The man who works for opacmare service in La Rochelle told me that they often change the hydraulic oil due to rusty ironparts from the rotary actuator and that these parts may block the mechanical switches.

Re: Fresh Water Leak At Aft Head
Hi Kent,
I think the answer is here.... " There has never been water found in the bilge until a boisterous sail last night, tacking into a 20kt wind. Found at least 10-12 liters there. It's only barely salty to taste." I had exactly this scenario on the way to Tahiti some years ago. Water sloshing around in the space under the aft head. I tried and almost convinced myself that it wasn't salty, but it was...... Where did it come from? The seals on the rudder shaft. We were on starboard tack in big seas for quite a while and the water pressure from the pounding forced water up past those compressed rings. It then worked its way along the port side under the aft bunk and went to the lowest point under the aft head. Tightened up the nut and that stopped it temporarily. Permanent fix was to replace the shaft sealing. All the best Alan Elyse SM437 |

Height of the SM Mizzen Mast
Richie Whyte
Gentlefolk,
A quick question for anyone who has done this recently. I am ordering a new AIS and need to tell the supplier how much VHF cable I’ll need. I’m presuming the black box AIS will be mounted in the Nav Station area. I can measure the circuitous route to the bottom of the mast (in the aft head panel beside the mirror) but I can’t get a figure for the height of the mizzen mast of the Super Maramu anywhere. Anyone got any ideas? Richie Richie Whyte ‘Why Knot’, SM2K#261 Kos Marina, Kos Greece |

Hi Andrew,
I had to remove the rudder in the past weeks for a succesfull repair. From what I saw the nylon bushing is just water lubricated. Those 2 screws on the side hold the bushing in place. Olaf Bauer made a description of the rudder removal which may help you too: https://amelyachtowners.groups.io/g/main/files/AMEL%20SM2K%20Rudder%20Removal/Rudder%20removal%20at%20a%20AMEL%20Super%20Maramu%202000.pdf Best regards, Stefan Jeukendrup sv malaka Queen SM2k #348 @ Northern Ireland |

Re: Opacmare - replacing sensor
Hi Paul, Actually I have been considering to enhance the system using an Arduino controller or similar. But builing something like that and also making it reliable takes time and I had other priorities. The passerelle has several flaws, not only the electronics. I don’t think the sensors themselves are bad design. The connectors and wireing is more of a problem. The current control system is crude but does the job. If improvements are made it would be in adding sensors and automate the closure/opening sequence a bit more. In the end it would add a fairly limited amount of functionality. For me it would be more a challenge to do so then a solution to a problem. So maybe I will take it on at some point but not now. The main problem with the thing is the ingress of salt water in the rotational actuator. I had to replace mine at 6k$ cost. Protecting it totally from seawater is not so easy.

Re: What to do with LiFePO4 batteries when the boat is layed up?
Matt & Michelle
For what it is worth....
Michelle and I just received our shipment of Victron 200Ah LiFePO4 batteries. I measured all six of our batteries as received, and they are at an identical 48.2% SOC. I purchased the batteries from PKYS (shipped direct from Victron). Peter Kennedy (great technical guy to work with) ensured I purchased a small Victron battery charger to fully charge each battery individually prior to install. To Scott's point, Victron is not going to have inventory age and expire in storage as an ongoing money making enterprise, and the SOC matches what all those boring peer reviewed studies say. Just another data point worth considering. If anyone is considering doing a LiFePO4 conversion, I would strongly recommend you read Scott's write-up, Bill Kinney's post, and then the peer reviewed papers. The lithium conversion world is the wild west right now, with multiple companies selling silly "drop-in" full conversion batteries. You are ultimately changing the power distribution architecture of your boat which has significant life safety risk. Finding the right experienced technical resources has been challenging for us. One can easily see why insurance companies are nervous, and I suspect redneck engineered conversions will be a fun new topic of new used boat sales in the near future.

You are such an intelligent guy I wonder as to whether you have considered re engineering this marvel of Italian engineering into a more reliable solution.

I forward you the solution that Robin from SV Carré d’As sent me. He had the same problem and me too. It is actually very easy. Best, Lior "We found the solution:
find the cable that comes from the pump in the 230V Tableau in the galley and connect it to the side where there is always power - secure it with a 5 amp fuse and you are done!

Re: SM & A54 Main + Mizzen manual furling gear boxes - seals, o-rings, dust cover … + source(s) ???
Vladan SV PAME
Bill,
the extra seal number 5 is 45 x 58 x 7 It’s difficult to check size of the motor seal without taking off motor. For sure shaft coming out of motor is 45 mm so it can be. Also as I see Danny is mentioning slightly different size of seal so could it be that not all manual furlers installed through production line were same? Best Regards, -- Vladan A54 #157 SV PAME |
