To properly lube the steering cables, they must be removed from the
engine on a regular basis. The bend in the cable makes that difficult,
but not impossible. Something to keep in mind, do not ever kink the
cable. Use care in removing and replacing the cable in the mounting
tube on the outboard. If you have any doubts about your ability to do
this, take it to your favorite dealer.

Crud tends to build up around that area. Clean it. Use a good
penetrating lubricant to help loosen things and ease removal. Something
like PB Blaster or Marvel Mystery Oil. WD-40 is almost a waste of time.
Be sure to remove all necessary hardware on the engine to get the
cable free. It should pull out of the tube and you can shorten it's
length by turning the wheel one way.

Once removed, turn the steering wheel the other way and extend the
cable. You will find the cable inside of a double sleeve arraignment.
It's inside that gets all corroded. Where you cannot normally see it or
lube it. Clean it well, inspect it, replace if necessary. Once clean,
lube it with a good quality marine grease for that purpose. Lube all
exposed cable and sleeves.

Re-install and perform this function at least annually. More often if
used more or anywhere near sal****er. Yes, hydraulic steering is really
nice with no more cables to lube.
