Re: C Drive lower prop shaft seals for 1992 Super Maramu

The three seals are 45x65x8 double lip seals as supplied by Amel.
The bronze wearing out bushing is custom. Most prop shafts and therefore inner diameter of the bronze bushing are 40mm, mine is 35mm. The outer diameter, where the shaft seals ride, is 45mm.
The o-ring inside the bushing is generic (mine is nitrile/buna 2x35mm). Most are 40mm in diameter to match the 40mm prop shaft.
Regarding oil type, I can share what was told to me directly by Amel in November 2021:
"The recommended oil for the C-drive is 15W40 and you need 8 liters. It is not recommended to use a thicker oil on this system. It is true that there are some confusing discussions about this issue especially on the different social networks."
My C-drive is the older aluminum style unit, which is different from the one in the original photo of this thread and the majority of Amel C-drives out there (which are iron).
When in doubt, ask sav@... directly. Share photos of the parts. Be polite and say something pleasant before starting into your questions and parts requests.
Hope this helps.
