Jason is correct about the number of ullage motors. What you're thinking of, ka9q, are the retro motors on the S-IC stage. There were normally eight of them housed in the F-1 engine fairings. On Apollo 15 the number was reduced to four, however this was increased back to eight starting with the very next mission.
