Probably not, on the black box, but the crash analysis of the aircraft pieces being assembled as we type in a warehouse hastily-rented by the NTSB somewhere close to the crash site, will tell us.
Look, the engine mounts were probably designed to shear off with the forces of a water landing. I’m thinking that things worked as designed, and that this is one of many elements that led to this event having such a good outcome - a very experienced pilot who did the right thing, engines designed to shear off, many boats in the water nearby, passengers acting and crew acting coolly to get everyone off, etc.
