It does rev freely in neutral.. Prop has had no service in two years

Ben, everything you describe points to a dirty prop and hull. Heavy marine growth particularly on the prop can virtually stop engine. Does it rev freely when in neutral? 

The correct running temp. is 80C around 175 F easily checked with a laser temperature reader to confirm validity of your gauge.

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 would agree with a lot of that but receiving a simple text message can also be easier if you are in a low bandwidth situation.

 

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. If that can be made to work then it would seem an ideal offline tool to have a local copy of the forum messages and would be very useful when away from Internet access. I note also that the creator offers a bulk discount - I wonder if they would give forum members a discounted price.

 

Also it looks like it exports all the messages and attachments in SQLLite format so it should be technically possible to transform this into a format that could be migrated to another forum.

There is only a breaker for the bow thruster control circuits on the main panel above the Galley - there is no breaker for the motor itself as currents can get to over 400 amps

Richard,

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.

I will check into this as well. I'm a programmer by trade and would be happy, if needs be, to write something to transfer the data. I've been wondering if there was a way to "archive" this group for times of need in the middle of the ocean anyway!

I would hope there will be a reasonable amount of time before anything drastic happens to yahoo groups.

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.
