Narrative:
Departing ewr on newark 7 departure; ny departure control instructed us to climb to 6000 ft turn right to 240 degrees and intercept the col 350 degree radial inbound. Aircraft was on autoplt; climb power. At about 5600 ft I hit some wake turbulence either from departing B747 in front of me or other crossing aircraft; wind was light 140 4 on surface. Autoplt disengaged due to turbulence and before I could level the aircraft manually smoothly the aircraft had passed 6000 ft and I stopped the climb about 6340 ft. Departure called and reminded us to level at 6000 ft. We acknowledged and there was no further conversation. We were then handed off to ny center. There were no conflicts with any other aircraft.

Title: CE560 CAPT RPTS ENCOUNTERING WAKE TURBULENCE DEPARTING EWR APCHING 6000 FT THAT CAUSES THE AUTOPLT TO DISCONNECT. THE ACFT EXCEEDS THE CLRED ALT BEFORE THE FLT CREW CAN REACT.
Narrative: DEPARTING EWR ON NEWARK 7 DEP; NY DEP CTL INSTRUCTED US TO CLB TO 6000 FT TURN R TO 240 DEGS AND INTERCEPT THE COL 350 DEG RADIAL INBOUND. ACFT WAS ON AUTOPLT; CLB POWER. AT ABOUT 5600 FT I HIT SOME WAKE TURB EITHER FROM DEPARTING B747 IN FRONT OF ME OR OTHER CROSSING ACFT; WIND WAS LIGHT 140 4 ON SURFACE. AUTOPLT DISENGAGED DUE TO TURB AND BEFORE I COULD LEVEL THE ACFT MANUALLY SMOOTHLY THE ACFT HAD PASSED 6000 FT AND I STOPPED THE CLB ABOUT 6340 FT. DEP CALLED AND REMINDED US TO LEVEL AT 6000 FT. WE ACKNOWLEDGED AND THERE WAS NO FURTHER CONVERSATION. WE WERE THEN HANDED OFF TO NY CTR. THERE WERE NO CONFLICTS WITH ANY OTHER ACFT.
