Re: Prepping Onan for short-medium term non-use?

Hi Scott;

 

It is nice to hear you have had such success with the conversion to Lithium. We will be doing the same in the next battery change.

 

I would consider running the generator periodically under 80% load (I would say once a week) for about an hour. Although winterizing is helpful in extending the life of a diesel engine and all related mechanical components, while in storage, lack of operation can be very detrimental to the longevity. Running the engine helps to lubricate the internal components and prevent rust and corrosion.

 

Also, when on any type of passage, Amel recommends running the generator and the engine at least once a day, to prevent sea water from working its way back into the cylinders through the exhaust.

 

Happy Sailing;

Subject: [AmelYachtOwners] Prepping Onan for short-medium term non-use?

 

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?

Danny , Its not the top swivel that is the problem, its is the swivel/car which pulls up the sail that is having a problem. I suppose I will first flush it out well before I take it apart and see if that helps.

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

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? :)

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

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.

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.

Mizzen furler

Patrick McAneny
 

I have a problem with the mizzen furler not able to rotate 360 degrees. I have determined that the problem is within the swivel part of the furler. It will rotate freely ,but then binds up and needs to be forced to be able to rotate. I need to take it off and separate the two parts , I assume the bearings have degraded . When I slide it down and off the foil will ball bearings fall out ? How are the parts separated ? Has anyone done this before. I will also try to disassemble the gearbox to clean and grease it while it is off.
Thanks,
Pat

Paul,

   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.

Could I ask for some clarification on the use of the Racor filter gauge. My understanding is that this is a vacuum gauge and the higher the reading the more fuel blockage there is. Reading below runs counter to this interpretation. So how does one read this gauge and at what reading should I be concerned enough to swap filters?

Thank y'all for the suggestions and the link.
This morning I rechecked the probe I took from the engine fuel filter. It was sitting overnight in a small glass jar with a sealed lid.
In daylight I was able to spot a ~3mm diameter water bubble at the bottom of the jar.
I took probes from both Razor filters. The unused one was clean and no water. The other one had a bit of dirt and added a few more very small water bubbles to my jar.

Bill,
you asked why I didn't switch to the other Razor filter.
First the filter didn't look dirty from outside shining a flash light against it. Second the pressure gauge was showing no significant low pressure. 
And in case of dirt in the fuel I wanted to keep the second filter as my last reserve for a docking under engine maneuver.

We ran the Onan Gen-set last night again for an hour.
Today I did bleed the fuel with the manual pump again. Cleaned the air intake filter, which did not really show significant dirt.

I started the engine and it would run for a few seconds without load except the alternator. I tried several times. It would start at the second attempt and run for 10 to 20s and then drop RPMs. Putting the throttle forward made the engine speed up. But it would not last and die. One could hear that it was running on one or two cylinders.
I ran the Gen again for an hour to keep batteries charged. Then a few more attempts. When the RPMs where dropping I put throttle forward.
Finally I succeeded trying to keep it at 1500 RPMs. After 10 to 15 min it sometimes speed up to 1625 ... 1650 RPMs.
After 30 min it run constant at 1650 with the initial throttle setting that gave 1500 RPMs. One could occasionally hear a missed ignition. After a total of 45 min the engine ran fine still at 1650 RPM. Since batteries where charged to 90% I reduced to idle for a few min and the engine ran smooth at 850 RPM until I shut off.
We will see how it behaves tomorrow.

I observed a small puddle of diesel fuel at the rim of the manual pump which I had hit by accident diving for probing the razor filters. 
My current assumption is that I have a small air leak in the fuel lines, maybe the manual pump itself. Or the air was introduced when the mechanic checked the razor filters.

To Giovannis point, 
I had pushed the manual prime pump to help the engine start.

Will send an update tomorrow how it went.

Thank you and kind regards
