We are hauled out at Gulf Harbour, Auckland, because of caramel C-drive oil....and some keel scrapes that need attention. I've done the C-drive, now waiting on the keel.
Amel recommendation to change the C-drive bague d'usure, seals and oil is 800 hrs / 2 years.
Trust this of help.
Where in NZ is your Amel ?
Avec mes salutations les meilleures
