Thanks for this Graham and great to talk earlier

Looks like I’ll be dismantling the rack and pinion and trying to lube the troublesome cable 

I’ve also sent an email to Amel on the very slim chance they still have a few buried in stores somewhere or as you suggested the Super Maramu cables and cable ends are the same just longer!

Failing that I might post a separate thread on the forum to see if anyone has had experience of sourcing new cables. 

Thanks again for your help

NMEA 0183 wire color?

Duane Siegfri
 

I plan to connect the NMEA TX wires from my B&G Zeus 3 MFD to the Raymarine S3g Course Computer.  It's a bit confusing though, since B&G outputs to TX_A and TX_B and Raymarine has NMEA0183 connections noted "+" and "-".


I have one NMEA 0183 reference and they do not use + and - for wire designation since apparently there is no battery negative wire in the system.


Does anyone know if the TX_A wire connect to the "+" or "-" terminal on the S3g?

Hi Pat  I had the same thought as you, i.e. remove only one side.  Didn’t work, the “grip” of the car is so close tolerance that it can’t be rotated enough to slide off laterally from the remaining side of the “T”.  I incrementally whittled away at the sides of the “T” and found that only about 1/32 to 1/16th inch of the “T” top could be left in place on each side of the vertical web portion of the track.  

Don’t forget to protect the gel coat & metal parts from slips of the grinder.  I used an angle grinder for bulk work & Dremmel tool cut off wheels & grinding bits for closer tolerance work, finishing off with hand files.

Re: [Amel Yacht Owners] Volvos.......

Ian,

 The diesel engine governors that I am familiar with mechanically limit the engine RPM to a preset level by reducing the throttle setting.  If you are getting full revs. in neutral but not under load, I doubt that the governor is your problem.  I am sure that you will get more specific help here from others with the possible causes of your low revs.

Best of luck,

Will the engine run at 2800 rpm unloaded (in netural)?

If NOT, the answer is not fuel starvation (because that would take very little fuel) but a possible problem with the injection pump or speed governor.

If YES, then...  I am not sure...

Hi Nick,


That's very  interesting, and I shall follow it up--but I don't think my Volvo has a sensor like yours---it's 18 years old and no computer has been near it in that time !

In neutral the revs are fine.

It runs at 2000 revs happily even with the Onan on at the same time, so I don't think there can be any problem with the fuel supply being blocked.  It must be something on the engine.


The fuel injection pump was checked by Bosch in December 2016, 300 hours ago and was passed fit. Everything certainly worked as it should last season.


I am beginning to wonder it there is something wrong with the governor. On the 78hp Volvo  in the SM Amel govern it down to 60hp.  I assume that a governor works by limiting the supply of fuel. In neutral, you only need a small supply of fuel to exceed 2800 revs so the governor doesn't reduce the revs in neutral. However, under load, 2800 is tops.


Needless to say, trying to get an answer out of a Volvo agent in Athens at the beginning of the season is turning into a saga of its own.


Anyone who has sailed in Greek waters have any suggestions for a mechanic who knows what he's doing ?

Hi,

I had a similar  problem on my Amel 54 with Volvo 110hp turbo. Thought it was the turbo but it turned out to be the sensor  which measures turbo boost pressure. It is located on starboard side on the Volvo and 5 minute job to change but expensive part 350 euros. Problem solved. I had to get a Volvo technician to diagnose the fault with his computer though as I was unable to diagnose the problem.

Do you have an EVC  computer thing giving boost pressure? If that is stuck the EVC will limit the rpm. Sometimes these modern engines can be too clever! You could also check the turbo is sucking and the little arm goes back and forward. If it is stuck just work it with some WD40. If the boost pressure does not come up then I think it is the sensor.
Can you get 2800 in neutral? When I had my problem i could get 2800 in neutral but not under load.

Hi All,

I thought this subject had been reviewed so many times that there was nothing else to know. However.....

Last year our 78hp Volvo was partially rebuilt by the Volvo agent in Hyeres. Not a happy experience, but we did end up with an engine performing as it should. With a clean bottom and prop  the rev counter went up to 2800 with a top speed in calm water of about 8.4k, much the same as when the boat was launched 18 years ago. We are pretty rigorous about opening the throttle to max every 12 hours or so.

We put about 290 hours on the engine and then left the boat ashore till this month. I changed the oil and fuel filters. We have twin Racors before fuel reaches the engine.

Having launched, with a spotless bottom and Autoprop, we  motored for about 12 hours at no more than 1900 revs.
Performance was perfect- up to 7.1k at 1800.    I then opened the throttle but with the lever full ahead the revs would not exceed 2100.  At 2000 revs we do 7.3k and at 2100 7.7k, what I would expect. But nothing above 2100.

More than that, on four occasions when I have tried full throttle the revs have fallen back  suddenly to about 1500, on one occasion stopping the engine.

I should mention that the refit included a new turbo , injectors and exhaust elbow and the fuel pump was sent off to Bosch who confirmed that it was fine

Diving on the prop shows that it is still spotless.

My thoughts are that there must be a fuel shortage when I open the throttle; that there is sufficient flow up to 2100  for the engine to perform correctly but above that there is fuel starvation.  I have changed both the engine and the Racor filters again, in case some fuel bug had grown over the winter and blocked them. The ones I took off were spotless and the fuel they contained was also spotless.

Anyone got any thoughts ?

Thanks for this Bill. 
It gives me confidence to have a go at dismantling the rack and pinion unit. 
Looks like the SM has a very similar steering system
Another idea from James is that the clutch on the autopilot is not disengaging properly which would be an easier if potentially costly fix.

Does anyone know if and how the morse steering cables them selves are lubricated? 

Thanks again?

Hi Bill:  

Yes I considered amputating the track but there are two anchor screws in the track aft of the bolt and I would have been left with discolored gelcoat and screw holes where the amputated track was. Additionally, I wondered if Amel knew something that I didn’t regarding structural strength so I chose to be minimally invasive.  Still it was an emotional challenge to cut into my boat like this.
I am thinking of trying to use some clear Alodine treatment on the raw edges of the aluminum for corrosion control.

Steering stiffness (but not from rudder) ?

smiles bernard
 

Hello there group

I’ve been wondering about the source of the stiffness of my steering`

Following good advice from this forum I removed the Morse steering cables from the rudder quadrant

Once disconnected the rudder turned really freely so the stiffness must be in the morse steering cables or in the rack and pinion/steering wheel assembly itself

Rather hopefully I added some grease via the grease nipples on the rack/pinion. Sadly this did not help reduce the stiffness 

I’d be interested to hear if anyone on the forum who has experience of somehow reducing friction in the steering cables and/or taking apart the rack and pinion for service. 

Or has any thoughts about the likely stiffness and any things i could try

I assume the next step is to unbolt the rack n pinion and take it apart but I’m a little concerned about how easy it’ll be to put back together again!

I’ve attached a pic of the rack/pinion assembly on my boat in case its the same as others on the forum...I’m not sure if this system is also used on the super maramus?

Any thoughts or advice very much appreciated

Does anyone have any experience of replacing the steering cables? If so i'd be really interested in how this was carried out and where the cables were sourced from 

Many thanks in advance

Hello Amelians- Would love to get advice, so please indulge me. Situation: I'm in Martinique, three weeks from heading to Bonaire for hurricane season.........then Aruba, Columbia, Panama, and through the canal......i.e. about to head away from the island chain and abundant technical support.


Through owning L'ORIENT (SM2K #422) for 8 years (and being cheap), I've become fairly technically competent with the boat and haven't paid for a technician in years.........and owe a lot to the posts I've read here for that. While not every repair has been smooth I've found the answer is always in this site. In maintaining the boat, I try to balance opposing cliches......."don't fix it if it isn't broken"........and "you can't be afraid of your boat".


So, the other day I decide to test the engine and attempt to get the revs up while motoring...........can't get above 1900 RPM. No big deal........it must be a dirty prop, like always..........so I dive on the prop and find some peach fuzz and a few smalll barnacles but not enough (in my estimation) to cause the loss of revs (this has happened to me before quite often when I lived at Miami Beach Marina for 2 years).


So after cleaning the prop I test the boat again and am able to achieve 2800 RPMs without vibration or problem (a bit of additional exhaust smell maybe but I think that was wind direction). This still leaves me uncomfortable since I feel like there should have been more fouling on the prop.


I have in my spares 4 new fuel injectors, guides, fuel line, etc........everything I need to change the injectors; however this is a project I've never done before. I'm normally decisive in this situation but don't really have a direction figured out yet. So, what now ?


1) do nothing......engine has only 2600 hours and things seem OK now. Also, it might not even be the injectors !!!

2) pay a guy to change the injectors and test the engine (hate this option)

3) change the injectors myself (my uncle, the former chief mechanic for a major US city thinks I'm a wimp to even consider paying someone else.........says he could do this in an hour while drinking 3 Buds).


My hesistancy to reflexively go to the "do nothing" option is that if the problem re-emerges in someplace less saturated with potential help I will wish I had dealt with it now.


Thoughts ?




Re: [Amel Yacht Owners] Raymarine AIS not working on Furuno Chart Plotter?

greatketch@...
 

I can not comment on Furuno comparability specifically, but our Raymarine AIS works just fine with our B&G instruments. It did require a special cable adapter to connect the proprietary “Seatalk” connectors into standard NMEA2k system.

AIS data transmitted on the NMEA bus protocol should be completely comparable across manufacturers, especially since the unit sold by Raymarine is an industry standard AIS with Raymarine labels and connectors.

The Raymarine AIS unit on our boat was installed by the previous owner, and he had only interfaced it via 0183 to his laptop. When we bought Harmonie she had no NMEA2k network. Other than the cable adapter, the AIS was very much plug n’ play.

One of the reasons I have avoided Raymarine in general is their attempts to close off their system as much as they can. The whole point of a NMEA2k system is so different manufacturer’s equipment can play well together.

Gary, I also need to remove my cars and I guess this is the solution , I can now stop scratching my head , I was going bald. Do you think the car could be remove if I only removed only one side of the rail ? I was wondering if you could pick up one side and then slide it over and out. It may be too tight of a fit to allow it to be angled up. I guess I can answer this for myself when I do the job . Thanks for the source of the bearings.

Hi Chris:

I just undertook removal of my jib sheet cars on my SM 2000 #335 for two reasons.  1. one of the plastic sliders was broken on the port side and 2. there was hurricane damage to the toe-rail on the starboard side.  In my opinion, Amel made an error in extending the track too far aft.  You never need the car back that far and even if you are able to remove the "stopper" bolt that is about 6 inches from the end of the track, the car will not come off the track as it hits the chainplate/lifting ring.   I was able to remove both of the bolts on my tracks, but then was still unable to remove the cars due to that interference.  So, I used an angle grinder and very carefully cut the top of the "T"  of the track on both sides of the vertical member for a distance of the length of the jib sheet car.  I radiuses the forward ends of the cut and dressed and filed the track for a finished look.. & nbsp;Now removal of the car is accomplished by removing the "stopper" bolt then sliding the car to the narrowed area of track and lifting upward.  I hope that makes sense.  It was a tedious project and I recommend placing protection of the fiberglass and areas of track you don't want to damage as slips with the angle grinder are bound to happen.

Re: [Amel Yacht Owners] Low Revs.........

 

Don't underestimate the power of a single barnacle. A single barnacle located in just the right spot on a single prop blade on an AutoProp can cause that single blade to bight the water at a deeper angle, causing vibration and a loss of RPM.

AutoProp is the best all-round propeller for your SM, but does require meticulous cleaning for optimum efficiency of operation.
