Re: Oceanis 45 saildrive questions
I have the Oceanis B45 with a saildrive. Before reading the fine print on the MaxProp manual mine did whine. The solution was to momentarily put it in reverse after engine shutdown. The whining I did hear was because the saildrive was spinning in neutral.
Just for testing, put the gear in reverse to see if the whining stops. I believe the Beneteau policy for fixed props is to leave the drive in reverse, not positive though. Your dealer should check it out and advise.
