I was on Part 135 flight as a First Officer. During the departure and the climbout we had a strong jolt to the left of about 60 degrees. We first thought was a wind shear; but now believe was wake turbulence. We initially [were] given the BEKOL3A departure; but because of that; we were unable to fly the assigned course. The Captain tried to get the plane to straight and level flight; but we were already off course. After that we [were] given vectors to intercept and we were asked by the Controller the reason we didn't fly the profile. My immediate answer was that we encountered wind shear and the Captain tried to fly the plane safely and that we had the terrain in sight at all times. On my side; I did not have any control of the situation; except to support the Captain and respond to the radio calls.
