Prepping Onan for short-medium term non-use?
Scott SV Tengah
We have the Onan 11kw on our A54 and after fixing the solar wiring (bad install), we are finding that we don't need to use the generator anymore here in sunny Maui.
In the 6 weeks since we have been stationary, the generator has not been used at all despite running the dishwasher, washing machine, water maker, water heater, icemaker, etc. daily. Given Covid - I have no idea how long we will be here. At what point do I need to consider preparing the generator for non-use / wintering? Since we bought her, we have lived aboard full-time save for one month last summer, so we haven't really had to winterize anything yet. I considered running fresh water through the SW circuit, but wouldn't that passivate the heat exchanger zinc? Thoughts on how long we can just leave the Onan unused without active winterization measures? -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com

Re: Mizzen furler
Danny and Yvonne SIMMS
Hi Pat, before you start any disassembly try this. Lower the sail and flush the swivel with copious quantities of fresh water. Despite the fact it is at the top of the mast it will have salt in it and this is a common cause of the symptoms you have. As to the manual mizzen furler gear box mine was getting so tight I feared causing damage while turning the winch handle.. I took the fiber collar off the input shaft and squirted fresh water in vigorously. I then did the same to the gearbox top and bottom. I left the gearbox and the swivel to dry out on a sunny day and then sprayed both with silicon. Now the mizzen launches with a tug on the out haul line. No turning of the gearbox by hand the sail goes out brrrrrrrrt. The swivels on the main and head sail need the same treatment. Because they are operated electrically we are not so aware of the friction. Breakers popping during operation can be a symptom, as is the foil on the mainsail fracturing. Likewise bending of the horns on the headsail furler although there are other causes for that as well. Kind Regards Danny SM 299 Ocean Pearl

Talked to Jonas and he think that the mizzen and the one on the main is similar. But it sounds like you have managed to take it down now. Regards to Diana! Regards Ann-Sofie & Jonas S/Y Lady Annila SM232, 1998.

Re: Need help in Palma
Doug Smith
Thanks, I appreciate the ideas. I searched the SSCA, of which I am a member, and there are no hosts in Palma. A couple of hosts in the Canaries, but no one in the Balearics. Don’t post on Tran-ocean.org. This is a pretty fluid situation, and I spoke with the crew a few minutes ago, and have them staying another 24 hours. The shipping company is telling me the ship is upright and they have unloaded most of the ships. I am hopeful for more clarity by morning local time. We are most concerned that if we change out crew, it will mess up the loading and customs for the ship transport. If there was a fellow owner, stuck in Palma, it would make sense to switch out crew, but trying to identify and find a new crew on short notice (hopefully) might be worse.

Re: Converting my Amel 54 to lithium batteries: what I did, what I like and what I don't like (after one year of full time live aboard use)
Scott SV Tengah
Jamie,
Good to hear it's working out for you. Have you tried to run AC all night on battery yet? We draw 25-35% if we run just aft AC overnight. For your Mastervolt alternator regulator, I had the same problem and solved it with a solid state relay and two Hella relays. See #50689 We charge with 200amps nominal (120a Quattro + 80 a Skylla) and only see high temperatures at the very end of charging (95% SOC +) or if one of the cells is severely imbalanced relative to the rest of the cells in the battery. Note that this imbalance shows up as a voltage difference, but due to the flat charge/discharge curve of lithium, you won't notice it until 90%+ SOC. Can you monitor cell level voltage? With the Victron batteries, you can connect via bluetooth and do just that. Also I'm surprised you can't change charging current via VictronConnect on your PC. I typically connect to my Quattro using ethernet, but I connect to my solar controller via bluetooth (from my Mac) and can change everything via bluetooth. Keep in mind that you will need to revise how you think about SOC and longevity. Lithiums do NOT like being kept anywhere near full. I try to cycle mine between 40-85% (ideally no more than 80%) SOC and then charge it up to 100% once a month to balance out the cells, since balancing only occurs on the Victrons when they're nearly full. Independent literature indicates I'll get over 5000 cycles doing this. I know some who take it between 10-100% SOC daily and have been fine for a few years, FYI. Monthly charging to 100% also resets the BMV-712 battery monitor. Not sure which BM you have, but don't forget to change the settings on it to match lithium. Of course, you MUST set all the chargers to lithium profiles otherwise you will kill the batteries very quickly. So you've been thinking about charging cutoffs - how do you deal with low voltage cutoff? As mentioned in that post, I opted not to use the BatteryProtect, which would disconnect loads when there's a cell low voltage condition, but rather I'm trying to get the Victron charger/inverter to trigger the generator to start when cell low voltage and/or low SOC is encountered. Sounds like you're an engineer - want to help figure that out? :) -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com

Re: Mizzen furler
Patrick McAneny
Gary, I have removed the gear box and with the swivel in hand it will only rotate to a point and then there is resistant and requires effort to get it past that point,once past it turns freely almost 360 degrees and stops again until I force it by the spot. It must be an internal problem ,probably a bearing ,don't know what else it could be. I am just going to give the gearbox a good soak and spray some lub into it.
Thanks,
Pat

It is unclear to me what you are referring to when you say, "the problem is in the swivel part of the fuller". Are you unable to crank the winch handle drive more than 360 degrees?

The most common cause (in my experience) for difficulty turning the mizzen furling is due to "crud" build up of salt and debris on the winch handle drive-shaft within the bore of the mizzen mast. When I was re-assembling the mizzen gearbox (having discovered that dis-assembly was completely un-necessary) I found that if the gearbox shaft (item #10 in the exploded parts diagram in my file noted above) wasn't completely seated then the bevel gears would bind. Perhaps your shaft has backed out slightly causing this binding effect. I doubt that, but it is worth investigating. THERE IS NO GREASE IN THE MIZZEN FURLING GEAR BOX!!! I suppose it is possible that there is broken tooth on the bevel gears that might lock things up but you can inspect for that by viewing the gears through the mounting bolt hole on the side of the gearbox (where the bolts that hold in the mast go). Look at the file, separate the foil from the gearbox to assure the foil isn't binding, remove the gearbox from the mast taking care to note the order of the washers and spacers, inspect for broken teeth on the gears, remove, clean and re-install the shaft for the winch handle and only then if you still have trouble disassemble the gearbox. That disassembly is a huge job and will yield minimal results (watched Brian on Delos do that job and destroy the end of the gearbox, requiring new parts to be machined).

Hello Doug, If you don't mind I could post your message in trans-ocean.org . This is a german / international organisation with more than 5000 members. We have many people all over the world who could help. Membership is only 60 € per year and many marinas will give you 10% rebate. Seeing the pictures I expect a delay for you for weeks. You may perhaps think about of sailing the Med. and sail to US next year. My situation is opposite to yours - can't get to Fort Lauderdale from Germany and sail her back to the Med.

Need help in Palma
Doug Smith
Hey Fellow Amel owners. My wife and I are the new owners of Aventura, Amel 54-113. We purchased in Nov 2019, and began moving from Greece to Gibraltar and planned winter crossing in Feb/March to US. As many of you have also faced, we were restricted on traveling, and remain locked out of Europe. Our boat was in Gibraltar for 5 months, and so we arranged for a shipping company to transport her to US, which was scheduled to begin this week.
Since we were also unable to get into Gibraltar, we hired a crew to move her to Palma where loading would occur on a transport ship. Unfortunately, or fortunately, we were about an hour from loading, when the transport ship lost electrical power and its compartments on the starboard side flooded. The ship needed tugs to keep it from flipping over in the harbour. I am just glad we were not already loading, or tied up next to one of those massive ships, crushing ours. The problem now is I have a paid crew just sitting in Palma and cost about 1000 pounds per day. I am wondering if there are any fellow Amel owners in Palma, who could assist with moving the sailboat Aventura across the harbour, which would allow me to relieve the crew. I am not sure yet when they will allow for loading, but am hoping it will be in the next 48 hours. But that is still up in the air, since currently, the tugs are still keeping the transport ship from flipping. Even if you know of a captain who lives in Palma, that would lbe helpful. Looking for any assistance, Thanks, Doug Aventura, 54-113, in Palma, very far away from me.

Re: Mizzen furler
Patrick McAneny
Ann-Sofie, I am guessing that is the same one documented in Bill's book and it was the furler/swivel for the genoa .I saw that and thus saw that a plug needs to be removed allowing the bearings out in order to separate the parts . It appears that the mizzen swivel is of the same design. Diane and I met you and Jonas probably five or so years ago in Prickly Bay ,hope you guys are doing well. Diane showed me your new interior,looks great.
Thanks ,

Re: Mizzen furler
Patrick McAneny
Courtney, I assumed that the gearbox would have grease inside ,I know it would not be easy to open up,if it proves difficult ,I will just flush it out. However my problem is with the swivel part of the furling system,as it rotates it catches at some point and will not rotate without forcing it pass this point ,then rotates freely until catching again. I assume it must be a bad bearing or something inside causing a problem.
Thanks,
pat

Re: YANMAR 4JH3-HTE Diesel Engine RPMs drop and then it quits
James Alton
Paul,
toggle quoted messageShow quoted text
Most of the vacuum gauges that I have seen used on filter installations show a yellow band starting at around - 6 psi but that is not engine specific, just general. In my experience, with clean filters the drop should be almost nothing with the size engines we have and the correspondingly relatively small fuel flow. I have replaced a number of these vacuum gauges that were not functioning properly so I don’t actually have much faith in them. I do think that you are likely on the right path and are getting very good advice here. An air leak or a restrictive filter can certainly cause the symptoms that you are describing but there are other possibilities, a plugged fuel pick up tube, bad injection pump etc. . If changing the filter and trying to fix the air leak does not help, consider bypassing as much of the fuel system as you can to see if that corrects the problem to narrow things down. Running the engine from a jug and a short fuel line connected to the fuel pump can sometimes help reveal the true problem and to determine if the problem is with the engine or the fuel system. Best of luck to you. James SV Sueño Maramu #220

Re: SM 2000 head backflow and holding tank leak -second attempt
Hi MIke,
Although ours is an SN, without the notorious SM corroding copper sleeve, I plumbed my aftermarket holding tanks with 1 1/2" PVC pipe 20 years ago. Annual or so doses of HCl keep the interior mineral build up at bay and rubber flexible couplings at the deck and through hull fitting eliminate vibration issues with the rigid glued pipe structure. Imho, far superior than even the most expensive hose that sewage permeates with smells after a few years. PVC never permeates odors (well, at least for the last 20 years). Good luck with your project. Craig

Re: YANMAR 4JH3-HTE Diesel Engine RPMs drop and then it quits
Hi Michael & Robyn, This won't be new info, but will reinforce Bill's thoughts. I've had similar problems twice in the last 11 years if ownership. The first time was very much like your problem. It turned out to be a very small leak in the fuel line that never dripped fuel, but sucked air when rpm got over 2K. After I ran out of ideas, a mechanic bled the injector connections and saw a few bubbles. It took going through the entire fuel system to find the problem. I wonder now if I could have pressurized the system and found a leak. The second time the Yanmar only died when we were motoring and running the Onan to use the microwave. The Racor fuel filters inspection bowls looked clean and free of water. I opened the second Racor and voila, problem solved. I cut the offending Racor open when we got to port, and found the filter material disintegrating. Before that I changed the Racors only every few years. Now the get changed at least every year and before a passage. Good luck, let us know what you find. Kent SM 243 Kristy
