Err no it doesn't, the grease nipples you see on the saddle (front of the engine) just grease the sadle bearings. There is a tube that runs through these which the steering cable then passes through. Grease will not get to the steering cable from the saddle grease nipples.
Greasing a steering cable is difficult and since its quite an important part of the boat why not just replace it, they last about 5 years with normal use then just go ove the winter period through lack of use.
