It almost looks like that engine was once rope steered.....
So, remove the red cap form the Starboard end of the big tube that it tilts round. Stuff the steering cable through there, and tighten the big captive nut on the cable to secure. (if there is only one cover, might be worth pushing a cleaning rag through first on the end of a long screwdriver)
Then use the connecting (link) bar that you hopefully also have to connect the free end of the cable to the vertical bolt on that bracket poking out the front of the engine. (remove the U- shaped thing that is there already). You may wish to turn the bracket so it sits inside the "handle" - that way it both doesn't poke out as much and will give you slightly more responsive steering.
And if that didn't make sense post back and I'll post a pic of my old suz that has a remarkably similar bracket.
