No, they can transmit a LOT farther than that. The signal could be heard for several kilometers through water, and the black box is supposed to withstand depths of 6000m under water.
It's still going to be hard to find, but it's not like a ship has to be directly over it to hear the beacon or if it's a few hundred meters away they'll miss it. Unless the box fell into a canyon with steep sides that block the ultrasonic beacon.
