An outboard's swivel bracket allows it to turn port and starboard as well as tilt up and down. Included in this section is the trim/ tilt motor and sensor if fitted, otherwise tilting is manual as with in the video below. With forward steering boats, the hydraulic ram or push-pull cables also run through the centre of the tilt tube. The swivel bracket attaches the outboard to the transom of the boat either with clamps, bolts, or both. Steering and trim-tilt problems are diagnosed by looking here.
