Thank you Bill for this final and extensive clarification. Now, everything is clear.

Thierry BALLARD is a good man and a valuable resource to Amel and Amel yacht owners. I like him a lot, but if he told you this, it is not the practice of the Amel yards and it is not what is specified in an Owners Manual which was written at the time that Amel switched.
About the time that Amel began producing the 55, Amel yards began using 80/90 gear oil that Amel specified in the Amel 55 manual for the C-Drive (photo below). I personally audited Amel employees servicing an Amel 54, changing the C-Drive seals, wear bushing, and oil. They used 80/90 gear oil (photo below). I specifically asked about this and they said they were instructed by Amel to use 80/90 gear oil for all C-drive models. Two years later, I audited them again, and again the same 80/90 gear oil was being used by Amel. I took the below photo of the oil being used by Amel. Note the red circle to the left. There was a PVC pipe, valve, and hose attached to this container. The Amel technician placed the container on the cockpit floor, ran the hose to the C-Drive reservoir, and opened the tap. The exact amount of oil was in the container. I apologize that I did not get a better photo of the PVC pipe and hose, but I am sure that you get the idea.
The following is a page from the Amel 55 manual:
Bill, I thought that was only for the bow thruster , now for the C-Drive as well? I have still been using 20-40.

About 4-5 years ago Amel revised the type of oil for the Amel C-Drive to 80/90 Gear Oil

locked down home and out of reach of the boat, currently on the dry, and of my owner’s manual, I must instruct a technician about the change of oil of the Amel Z drive. Can anybody remind me the grade or type of oil and quantity?
Many thanks in advance
