Hubbard, 39, of Atlanta, had pleaded not guilty to all charges, including first-degree homicide by vessel.
Killed in the incident was 11-year-old Kile Glover, stepson of R&B singer Usher.
Glover and his father, Ryan Glover, were vacationing at Lake Lanier when Hubbard crashed a personal watercraft into the boys' inner tube July 6. Kile died at the hospital July 21st.
Regarding the injuries suffered by Glover's friend, Jordan Shepp, Hubbard was also found guilty of serious injury by vessel, reckless operation of a vessel, unlawful operation of a personal watercraft and a boat traffic violation.
