Remove the factory nut. This nut can be as large as 1.5”, so have a large wrench available. Since this nut is likely to be discarded, if you don't have a wrench that large a set of channel locks may be used.

NOTE: It is not necessary to remove the factory nut if at least three threads are already exposed. The Steersman can be threaded onto the tilt tube alongside the factory nut.

NOTE: If when turning the factory nut the threaded tilt tube rotates, it may be necessary to secure the tilt tube from the starboard side of the outboard, where the cable is attached, to keep the cable from twisting. One good way is to tighten the two nuts on the cable side against each other and hold them with another wrench while the factory nut is removed. If your factory nut is “welded on” with rust, you may need to use penetrating oil.
