RedactedNarrative: WAS PULLING A WAKEBOARDER  AND WE WERE 30 YARDS FROM THE NEAREST VISIBLE DREDGE PILE.  SPEED WAS 25-27 MPH.  ALL OF A SUDDEN THE DEPTH FINDER WENT OFF AND THEN WE HIT AN UNSEEN DREDGE PILE.  I IMMEDIATELY STOPPED THE BOAT AND PULLED UP THE TRIM.  GOT THE WAKEBOARDER OUT OF THE WATER, IN WHICH THE WATER CAME UP TO HIS UPPER SHINS.  LIMPED THE BOAT BACK TO SHORE AND PULLED IT OUT OF THE WATER TO SEE THAT ALL THREE PROPELLER BLADES HAD BEEN BROKEN AND DAMAGED AS WELL AS THE PROPELLER HOUSING HAD A HOLE IN IT WITH GREASE LEAKING OUT OF IT.
