We took off out on Runway 13L; Kennedy One Departure - Canarsi Climb; with gusty winds and behind a B747. We waited two minutes for separation and max power was used. After takeoff at 400 FT LNAV was selected and a left turn direct to Canarsi VOR was flown. During the climb we experienced some turbulence and we overshot the Canarsi VOR and the speed below 10;000 FT. We corrected our speed and returned to join the departure. No involvement or query by ATC; the flight continued uneventfully.
Air carrier First Officer encountered possible wake vortex departing JFK that resulted in course and speed deviations.
