Steering problem

Hi all,
Question: Can you advise me how to free up/lube my cable steering on my bass
boat? (It is the sealed cable type w/ a rack or flat geared surface at the
wheel...which I was able to lube.) I also lubed the arm at the engine)

It has apparently rusted on me over the winter and I cannot seem to get it
lubed.

I tried to remove it and see if i could get the cable out but to no
avail...all I could manage was to turn it around and around while loose
which freed it some.

I'm stuck here...any help or advice would be appreciated.

Thanks in advance,

Suthern
