Steering Rack Adjustment
Stephen Davis
We are just finishing up with final adjustments after replacing our steering racks, pinion, and steering cables, and have a question about how tight the racks should be. The racks are held together by 2 threaded studs with 2 cap nuts facing the galley. Should these 2 cap nuts be tightened enough so the racks do not move at all, or be a bit looser which allows the racks to scissor back an forth a little? I can't find anything written about this, and I'd appreciate it if some of you could look at your steering racks and let me know if they are a little loose, or if you are unable to move them. My vote is for very tight with no movement, but would like to know how they are adjusted on some other boats. Thanks in advance for your help. Steve Davis Aloha SM 72 Ko Olina, Hawaii

Thanks to the person who linked my post to the appropriate conversation. Yes, they are marine deep cycle flooded lead acid batteries. Bill, thanks for what I am taking home from this: no need to look further for problems with the cells or system and keep the terminals tight. Mark Isaac SM391, Lulu South Freeport, Maine

Re: Generator exhaust
MIchael,
Are you installing a name brand generator (Onan, NorthernLights,etc) or are you putting together components yourself? If name brand the installation instructions should certainly cover this clearly and it depends on the genset size. For example, the older NL 6/4.8kw (which has a Kubota 10hp engine) calls for 40mm throughout and the exhaust elbow is 40mm (the new 6/5kw model has 38mm). Their 12/10kw with a 20hp engine has a 51mm elbow. In general, though, you don't want to introduce a reducer. If the exhaust elbow is 50mm, then carry that through, unless the manufacturer specifically calls for the reducer (to increase exhaust pressure - unlikely).

Can anyone help with the reasons why the hose is reduced in diameter? The generator supplier advised to have a 50mm hose going on the water lock outlet. Thanks

Re: [Amel Yacht Owners] New ultrasonic DST sesnor from AIRMAR
dbv_au@...
Hi Bill, [sorry, the earlier message 'got away' from me before I could properly complete.] When our Sonic Speed failed, we regained Boat Speed by replacing the preexisting depth-only sensor in the underfloor compartment outside the forward head with a paddle-wheel DST800. The DST800 uses a 51mm (2") form factor, and was a drop-in replacement. The UDST800 is also a 51mm (2") fitting. Noting however that the UDST800 processor requires a separate power supply, and the specs sheet says that this is 12VDC. Cheers, David Perigee, SM#396 Spanish Water, Curaçao

Re: [Amel Yacht Owners] New ultrasonic DST sesnor from AIRMAR
Alan, Interesting. I cannot remember...is the SM Amel-installed B&G Depth Transducer 2" as this combo is also 2"? If so, this is an excellent option when the sonic speed sensors fail.

Re: Ebersprecher. Heater
If I were you I would select a Webasto diesel heater. They are virually the same devices as the Eberspächer but from what I recall the electronics on the Webasto are at bit better. Also they have a more spread dealer network. On our boat Amel installed a Webasto Air-Top 5.5 kW heater. These things are a pig to install after the boat has been build as you need a lot of cables, hoses and (isolated) ducts. So careful planning is required. I would ask a fellow Super Maramu with a factory installed heater about the exact routing of the ducts to avoid inventing the wheel twice.

Re: Battery Compartment Explosion
greatketch@...
Mark,
Sorry to hear about your excitement, but glad the only damage was to the boat. I assume you have standard flooded lead acid batteries--if not--then things are strange... Just from normal charging, hydrogen is being generated by the batteries. It would be a bad assumption that a passive vent is sufficient to ALWAYS keep the battery box hydrogen concentration below the level that will ignite--given a spark. The problem is that hydrogen has such a very low flammable limit in air, between 2% and 6% depending on how you define it. Certainly local concentrations of H2 in the box could get that high in normal operation. And a loose battery cable certainly can create the needed spark... Moral of the story... battery cables need to be kept tight, and any kind of equipment added inside the battery box need to be ignition protected--or better yet mounted outside the box.

Clothes dryer on a A54
For those who are interested.
I just removed the dryer from the forward head. This was because it tripped the RCD breaker because of some grounding fault. Removing is quite the puzzle. The shelf that sits on top is screwed down with two screws in the back and is velcro-ed to the top of the dryer. However loosening this does not mean you will be able to remove it. The nice piece of wood that decorates the shelve prevents it from getting out. By feeling the vinyl at the back you can spot two screws that are underneath the vinyl. These hold the wood. By pushing a screwdriver (Pozidriv) though the vinyl you can unscrew them. Then the wood is only retained by some double sided sticky tape. Now also remove the small shelf in the back. It's held in place with two (visible) screws. Next you need to go under the sink. There is a access hatch held in place with two screws. You can just move this to the back to gain access. Now you will see (when you dive deep enough) the airhose and the two knurled knobs that hold the thing in place. Remove the knobs and the hoseclamp. Now put a thick blanket over the sink to protect it. You can just tilt the dryer foreward to have it lean on the sink. It helps to remove the tap first. Now you can access the innards from the back and top by removing a lot of screws. Do not remove the back panel itself, only the smaller cover that sits on the back cover. You cannot remove the dryer from the heads altogether unless you take it completely apart. Both the hatch and the door opening are too narrow. Amel actually cut the lower back corner off the dryer-housing to make it fit the space available. They also re-routed the hose from the back to the bottom. Quite the creativity there. I found the heating element to be busted, it had a short circuit between the poles and the housing. I think the dryer brand Minea is no longer sold but it is also sold as "White Knight" model C39AW. This is still for sale in the UK. On Ebay you can find loads of heating element replacements for this thing. I'm going to order two of them just to be sure the first one does not break down anymore. Regards, Arno Luna A54-121

Re: Generator exhaust
greatketch@...
Michael,
I can not give you an authoritative insight into Amel's reasons for reducing the size of the hose, but... The total volume of the exhaust hose is a design criteria for the water lock. The box needs to be able to catch and hold at least one hose full of water without overflowing back to the engine. If the hose run is long, then they might have needed to neck it down a bit to keep the volumes matched. If the horsepower of your new genset is equal or less than the original installation, then I would match the exhaust system as originally designed. If your new genset engine has higher horsepower rating than the original, I'd have an expert on engine installations look it over to be sure the exhaust system is sufficient.

Re: [Amel Yacht Owners] Re: Sunbrella
In our part of the world, ordinary domestic bleach now contains not only sodium hypochlorite but also sodium hydroxide...this is the same formulation as another product called Exit Mould that sells for something like 5 times the price of "bleach"
This product has to be the ultimate mildew killer...we use it for cleaning the cabin top, acrylic fabrics, the "blue floors"....wonderful... Cheers Alan Elyse SM437 Port Havannah, Vanuatu

Re: [Amel Yacht Owners] Anchoring in deep water in the S Pacific.

Hi, Agree with Bill’s comments. We have anchored out in steady 30 kts plus with gusts over 40 kts without difficulty. Our only addition is a long nylon snubber of 10 to 15 m to ensure maximum benefit of chain on the sea bed. Mike & Peta Solitude SM 2K 461

Re: Battery Compartment Explosion
Well that will be the case because if you have a bank of series connected batteries each battery will discharge into the other and eventually they will equalise and all will read the same.
You probably have 6 parallel banks of 2 x 12v batteries in series ? (standard Amel setup) However if you charge the whole system and then immediately disconnect each battery you may well find that they are not all the same. We have 6v batteries..4 in series and three of those banks in parallel. We had serious issues with battery failures 12 months after the new batteries were installed, probably caused by the slightly different internal resistance of each battery in the series chain. Some batteries were being more charged than others. We replaced the failing batteries (under warranty..hard to believe, but it happened) and installed battery balancers on each bank....they make sure that each battery in the series chain receives the same voltage Since then ... 2 years..we have had no battery failures and our 660Ah house bank is still 100% capacity. We monitor and log voltages vs capacity on the Link 10 compared to actual discharge...we never go below 80% and so far all the measured parameters are consistent. BTW our batteries are AGM .. so limited gassing issues and almost no possibility of explosions ! We have 600W of solar with a Victron MPPT controller A D400 wind generator that seems useful in gale force winds, but o'wise...PITW 100A Victron charger 30A Pro Mariner charger 175A Leece Neville engine alternator coupled to a Next Step II regulator AND they are all set for the same (batt Manfr rec.) voltages, absorption times etc And so far ...it all seems to work ! Hope that helps Cheers Alan Elyse SM437 Port Havannah, Vanuatu

Re: Sunbrella
rossirossix4
We use the 303 products as well having made our first application to the exterior (only) when the bimini was 2 years old. Note that they make a multi cleaner as well as a fabric guard (keep the Fabric Guard off any clear vinyl or wipe it off immediately).
Regarding the prevention of mildew we regulary and thoroughly rinse BOTH the exterior and interior with fresh water on a regular basis. We don't scrub it, just use a moderate fresh water spray. Frequently it is the organic material in salt water spray that supports mildew growth while the salt keeps things moist. Looks kind of unusual spraying the inside of bimini (and enclosure) but this gets salty as well. If you have a canvas dash/wheel cover and helm seat cover it makes this process a bit easier.
