Hello Volker, unfortunately you will have to change the seals to remedy this problem.
Normally when we change the seals we also change the wearable bushing. All available thrue Amel S.A.V. Santorin where produced with 2 différents Amel transmission, one small in aluminium or the same as SM in cast Iron. You need to know before ordering parts.

Dear Amel Owners,

I bought my Santorin (027) 3 month ago and getting her ready for the first move - from the port I bought her to my home port in Langkawi/Malaysia. Its a trip of approx 1200 Nm - but round Singapore where authorities are very particular.

I checked many systems already and mostly they are in working order, however the C Drive reservoir has signs of water in it,so its obvious that the seal on the shaft has not doing well.

I have 2 questions at the moment:

1. what oil is needed for the C Drive - I presume ATF?
2. any idea to reduce the water/oil mix and top it up with clean oil? - there is NO possibility to haul out the boat where she is and I need to move her in this condition..... l hope the wind is with me and I do not need to run the engine too much...but there is a big chance that my luck is not always with me....

Any suggestions are most welcome!

Hi Volker,

Amel uses now SAE90, 15/40 is also ok, but no ATF!  ATF is used for the gearbox, not for the drive.

Alan,  good video! thx.

SSB installation and troubleshooting is sometimes tricky. I made my engineer's degree in electronics and telecommunication and are an active HAM radio user since many years, but - even beeing a kind of professional in this area - it took me some time to get my installation working fine. There are quite a few factors that might influence transmitting, also outside the active HF elements (e.g. compressor of the fridge...:-) ).

most important - imho - , if the ground is ok, are "connections", good soldering at the connectors and the right cables, and understanding that the antenna starts at the tuner :-)

fair winds, herbert, SN120, OE3HLA

Hi Arnold,

thanks for the Info! 

So far my plan is to suck out as much as I can from the reservoir and/or gearbox and refill with clean oil....

Wish me luck for good wind so the engine will not been used that much,

cheers ,

Hallo Volker,

attached you will find the manual and drawing for the C-Drive!!
The oil is the same as for engine 15/40!!
You must lift out for repair the seal.

I would test the SWR (stand wave ratio) of your system. It tells you how much energy which is going out is reflected. With a device like this: (there are others which can do the same)

https://www.radioworld.co.uk/daiwa_cn-101l_meter_1_8-150mhz

And by the way: do you speak loud and clear when you transmit, and close to the microphone... ? 😉

Did you mention what type/brand of SSB you have?


Re: SSB Ground

Herbert Lackner
 

Joerg, 

* what cable did you use for connecting the antenna with the tuner? should be a GTO-15 and no coax / copper cable. This is sometimes the problem.
* make sure that this cable is away from other metallic objects and that it is as short as possible, it is already part of the antenna - and the area where most of the power is transmitted
* connection from this cable to the antenna (and tuner) is critical! minimum resistance necessary!

checking/measuring/testing the system (standing wave ratio etc.) needs some specific technical HAM radio knowledge.

Re: SSB Ground

Joerg Esdorn
 

Thanks very much everyone for responding.  I had thought I would disconnect the tank from the common ships ground and connect it to the SSB ground.  I have been checking my connections since the boat was new in 2016 and replaced the cable from the transmitter to the tuner, replaced the antenna cable from the tuner to the whip - connection to the whip was not good, replaced the cable connecting the Dynaplates to the tuner with copper tape.  All these things have made a difference between nobody hearing me to people now hearing me ok some of the time.  But as I said in the original post, I still often  have the situation where I can hear another boat quite well yet they cannot hear me.  This indicates to me that my transmission isn’t as good as that of the other boat.  I have been told that the whip antenna is not as good as the insulated backstay on most boats in low frequencies - the MedNet mostly operates on the 6 MHz band.  So that may be one reason.  Dave, many thanks for sending the troubleshooting articles.  What instruments do I need to test the system?

Hi Frederic,

Did amel supply these parts for you? I'm hoping to replace the same mounts in the coming weeks as the engine is out of our Mango.

Thanks,

Re: SSB Ground

HF shall do no harm neither to the Amel bonding system nor to all connected metals, even if transmitting with high power. It is the DC connection that has to be avoided, and this DC connection will be created by attaching tuner ground to the bonding system. To avoid that this connection has to be "DC separated" by capacitors (HF coupling capacitors, bunch of them soldered together), then the bonding system can be used as a nice HF ground without negative impact.  Only if there is no dynaplate!

herbert, SN120


Re: SSB Ground

Dave Ritten
 

Hi Joerg I believe that it is hard to improve on a direct connection system using dynaplates. If the connections are good and the dynaplates are relatively clean then I am not sure that extending the ground by adding capacitively coupled (internal foil) or bulk (tanks/engine) will increase performance. A while back I came across an article (which now I can't find!) which was doing a relative test of a KISS counterfoil and other options, they found that a simple connection to a bronze through hole gave very good performance.  I would first be focussing on power to the radio, cabling connections and condition, antenna etc. No doubt you have been through those tests but I attach a useful article that gives some guidelines about trouble shooting marine systems. Having a good SWR meter and a dummy load are invaluable tools in working through a process of elimination. In my experience bad connections due to crimp only PL251 connectors and corroded terminals/cable often is a problem on TX. All PL251 connectors must be soldered. Replacing the ATU/antenna connection and checking that it's routing is clear is also another gotcha. Antennae also fail - try the antenna test in the article. When trying to fine tune a system the biggest issue is measurement - how do you actually know that your system is underperforming when there are so many variables like propagation conditions etc. You have to rely on distant boats to call out what your transmission is like and that is very subjective based on their opinion, location and their receiver etc. I discovered a neat trick recently - there is a global network of enthusiasts who run software defined radios (SDR) that you can connect to over the internet. These SDR's were developed in NZ and known as the kiwisdr. Basically you fire up a browser on your laptop, connect to one of the kiwisdr hosts like https://ve3sun.com/KiwiSDR/  and then you can select an active receiver close to you and tune it to whatever HF frequency you want. You can then listen on your laptop to what that receiver is picking up. You then setup to transmit on that frequency and away you go - you can listen to yourself, as received by that site. This allows you to make incremental changes to your system and see if they make any difference. You can change frequencies and start running really definitive tests. You can change receivers to see how far you can transmit! For example you could attach a temporary strap to your fuel tank and see if that makes a difference, or get a sheet of copper and hang it over the side of the boat. I hope that this helps, at least I am sure that you will find it interesting to play with the kiwisdr network as it is fascinating to listen to what you can pick up on radio receivers scattered around the world.

Re: SSB Ground

Hello Joerg,

all the metal parts of your AMEL 55 (including your fuel tank) are connected together with the green/yellow wiring net and with the zinc anodes of your rudder EXCEPT the SSB ground-plates, tuner and transceiver.

DON'T CONNECT the SSB ground plates to anything else, especially the general zinc ground circuit !!!

You would then send a lot of power to all these metal parts while transmitting (moreover if you speak loud!).

The HF-SSB radio system must absolutely be isolated from anything else, including yourself (don't touch the antenna while trasmitting).

Moreover, connecting to something which is not in contact with water (your fuel tank) would not dispatch more power (the purpose of the ground plates is to dispatch the excess of power while transmitting).

You'd better:
- check all your connections on the SSB system
-clean the ground plates thoroughly (with some acid stuff in order to remove the scaling)
-check the continuity (0 Ohm) between the ground plates and the copper strap in the lazarette and the transceiver ground terminal
-check the good contact on your whip antenna

Good luck and be prudent with electrics.

Olivier.

Heinz,

I believe most of that area in an SM is a false floor that is glassed in above the actual hull.

On my boat 90% of Electric and electronic Problems are Connection Problems. This also applies to the SSB radio installation. I would check all the connections from start to end for corrosion and weak contacts.

And remember: the antenna starts with the wire from the tuner to the whip antenna (or isolated stag): no contact or approximity to other wires.

If not done already, check the SWR (stand wave ratio) of Your installation with an appropriate device. It gives you a hint of how much of the radios Energy that should go out is reflected.

If Nothing helps, open the tuner and check whether everything is ok or there are signs of Burning.
