Bill, 
It's been six months since anyone looked at bottom .. I'm doing so today.  I did find that prop fittings have not been greased in two years

The most common low rpm cause with an AutoProp is a dirty/fouled AutoProp.

It does not take much fouling to cause the blade(s) on an AutoProp to dig too deeply in the water causing low RPMSs. When was the last time you or someone else dove and inspected the prop.

Hello Ben,


I have a Volvo TDM 22 but diesels are diesels…

I encountered these symptoms on another boat… badly crusted propeller…

Other cause might be a faulty turbocharger.  Generally, we tend to baby our engines and this is not good.  I try to run at 80% or more power for 1 hour out of every 24 hrs of engine time.

Third possibility = a collapsed air filter.  BTDT.

Good luck.. at least the trouble shooting should be easy.

Re: [Amel Yacht Owners] Front opening refridgerator

I do not know if your reefer is mounted like mine. However Bill posted instructions as to how to remove it.

I will recap from memory to the right of the refrigerator under the sink there is an Amel black knob.- Remove it.

If you reach under the floorboard in front of the refrigerator  (from the bilge) you will find a black knob holding the floorboard in place . remove it and the floorboard.

Under the refrigerator there is a face panel fastened with a few screws. Remove the face panel. The refrigerator should then be loose. You might have to remove the front door to completely remove the reefer.

Hello!

I have two questions:

- I like to remove the front opening refrigerator on our SM#259 from 1999 to clean out behind it and clean around the compressor, but I can't find whats securing it, doe's anyone know how to pull it out?

- I think of changing the compressor to a water cooled unit and also the evaporator to save energy and reduce the sound from the fan, does it make sense to do that? I hesitate to buy the new units with drawer as they are very expensive.

I download and tried the yahoo forum offline tool - http://www.personalgroupware.com/index.htm - The trial version fairly quickly downloaded 4000 or so messages - I will try and leave it running and download the rest in the next day or so - the file and photos download didn't seem to work though.

Isn’t that for the control circuit of the thruster?

The bow thruster is , I believe 10 Horsepower which would be 7800 watts or a 700 Amp breaker figuring a 100% safety factor.

That would be one heck of a circuit breaker.

Re: Prop Shaft Electrolysis

jjjk12s@...
 


Is this a case of PREVIOUSLY the risk was so small, and the disandvatages significant, that the AC generator ground - neutral connection was not made, whereas nowadays, with readily available galvanic isolators and a more litiginous society the small risk overcomes the disadvantages and it should be connected. So it would be sensible to modify older designs that may have been correct at the time where circumstances have moved on. Amels have always evolved so modifying an older Amel to mirror a newer Amel's systems seems totally in order and not messing with Cpt Henry's concepts.

Re: [Amel Yacht Owners] Re: Engine Problems Amel 54

I think that the big problem with volvo marine engines, is the move to the common rail design. Remember that their marine engines are a small part of their buisness, so their supply of base engines are now probably all common rail. Even in road vehicles there has been major issues with this type of engine (I know of one Toyota with a common rail engine, which had 2 engines changed under warranty and I've had to change one fuel pump in my BMW).  So I'm wondering if the common rail engines are really suited to a cruising boat with the added problems of the marine enviroment. If not, is there a  more traditional aspirated or turbo 110Hp engine alternative.

Kent,  It may be the electronics , not the basic engine that is the problem. With all the Volvos out there, it seems odd that parts aren't available , I have heard they are expensive, fortunately I only remember buying an oil pressure sender and a timing belt. I guess I have been lucky ! It was great seeing you again when you stopped by in Oct. , maybe next time it won't rain for three days.

Hi Pat.  I don't know if older Volvos have more problems than Yanmars.  I do know how difficult it is to find mechanics who like working on Volvos, and how parts are often not stocked in the Caribbean, and seem outrageously expensive.
The newer Volvos have a lot of electronics designed to make them more efficient and "green", and troubleshooting them is apparently very difficult.  If Yanmar is doing the same thing with their new engines, I'd guess that they will have similar problems.

My experience has jaded my thoughts about Volvos, but it also says something that the Volvo guru in Puerto Rico recommended that I repower with a Yanmar if I was going to cruise in isolated corners of the globe.

I have been told that the Volvo was a Perkins, and that they have proved to be very dependable engines in cars and trucks in Europe.

Kent, I think you (plus war stories from others) have convinced me to ditch the Volvo. I can fix most anything if I study it long enough, but not this engine. I and many others have tried now for more than 5 months to identify the problem(s). Not being able to get service is beyond frustration. I have been through 7 different "experts" including the local Volvo tech for the area, who just sat in the cockpit for an hour philosophizing. Plus parts are absolutely ridiculously expensive.

I just don't want to take it apart any further to investigate. While it is not the end of the world to take off the head, putting it all back together will be time consuming, even if I do find a simple solution (not likely). Toast or not, I do not want to have to pull out the engine as a bunch of parts. And it would still be a Volvo.........!

I know that a much more mainstream Yanmar will be easier to service and get parts, and it will certainly be less expensive. I had one on my old boat and it was very reliable. Lots of folks who can help if need be. Right now I am waiting for proposal options.

I am on the hard and fortunately I don't have the kind of problem you had with the prop. I have figured out all the various Amel electrical systems (thanks to all who have warned me about the DC isolation relays Amel has installed), and I agree with your advice about the install. I will be here 125% of the time, doing whatever I can to minimize labor, while still ensuring warranty in the future.

Thanks again,

Make sure you understand the Amel electrical system completely and don't let them work on it while you aren't there!

In spite of all my trials and tribulations, I LOVE "Yanni", my new Yanmar.  I will NEVER own another Volvo!

Danny, I sure hope you are wrong about the installation costs. A new Volvo Penta D3-110 engine is about $21K, plus any hoses, fittings, muffler, etc. that might be necessary. I cannot see the install costs being more than about $4K to $5K. While granted a bit lighter, I had a brand new Northern Lights generator (with sound shield) "shoehorned" into a very tight space in my old boat, where there was none before, and the install costs (mounting, alignment, exhaust) were less than $3K (I installed the electrical systems and the raw water intake myself). I am budgeting about $30K for the job - that sure hurts just writing down that number. I could have a new truck for that!

There really is not that much to do if I go with the same engine - not sure if I will though. There is lots of work area in the engine room and access is excellent. A different brand would be more work of course. Plus I plan to ready the old one for haul out in advance.

I recognize that an overhaul would be less, but certainly close to half the cost of a new engine, and I will still have a questionable engine, even if I do get it running. While the parts would be much less, I feel that the labor to overhaul would definitely be more than that to install a new one. If I am going to do this (I feel I have no real options at this point), it needs to be done correctly, so I can rely on the engine if I travel with the World ARC in 2018. At least that is my goal.

I will be getting proposals, so we shall see.

If  a reputable engine reconditioner was available a full overhaul head and block is likely to be a whole lot less than a new engine. You have already replaced a number of expensive accessory items. Removing the engine for overhaul does not require the removal and replacement of all the electrical, electronic accessories and instrumentation. There is a bundle of these to the panel by the steering station. I have heard it stated that for budgeting purposes the installation costs of a new motor are generally about equal to the cost of the new motor.

Jamie,
 
Are you sure you want to rule out taking the head off and inspecting/trying to repair it? Even if you still end up getting a new engine your old one will be worth something second hand and the cost of that work may be recoverable eventually, especially if you get the engine running. Maybe you find any damage is limited to the head? I'm not familar with that engine but any chance it has cylinder liners that can be changed?
 
Maybe also consider getting the engine running or putting the new one in and straight away measure the exhaust back pressure. If it is indeed too high then you also have a reference for how much you can reduce it with changed muffler/shorter hose/larger diameter hose. I haven't read all these posts but maybe part of the problem might be the previous owner leaving the boat for extended periods without running the engine and the problem won't re-occur with more regular running and monitoring?
 
Regarding isolation, some engines are permanently grounded and others have a relay that activates via the ignition otherwise isolates them when they're not running.
