This is not going to help Azimut's reputation regarding electrical systems at all. Not that I feel for Azimut, they sell plenty of boats. But if someone can't locate a fuse box...I can imagine on a 80' boat there are more than one "fuse boxes" anyway. Sorry I am not able to assist. Azimut is in business and the hull number and phone call or email to them is your best bet, hopefully. I did learn more about Cyprus by looking up Larnaca though, cool spot.
Some of the Mut owners may know thru their experience. Sadly, I doubt the factory knows exactly where anything is. A good question from us would be; Fuse box to what failed device??
