It's always puzzled me that Honda do not quote a torque figure for the final drive drain plug on the 700 Deauville.
I have just been changing the final drive oil on my mates 2019 1800 Goldwing and noticed the drain plug (and washer) is exactly the same as the one on my 700 Deauville, same part numbers as well.
The torque figure quoted in the manual for the Wing final drive drain plug is 9 lb/ft or 12 Nm so I guess that would be appropriate for the Deauville as well, seeing as the plug and washer are the same.
