They retrofit Yorktown in 3 days instead of 3 months. The Japanese thought Yorktown was a different aircraft carrier-they could not imagine such a fast retrofit.

It was 2 days, and they thought it was a different ship because they thought the Yorktown was sunk in the previous battle, not because they didn't think it could be repaired that fast (although that's probably also true).
