Lubricating Teleflex Steering - How?
 

They make an aftermarket endcap with the zurc fitting built in that
threads into the tilt tube, but like everyone else said its probably
crap in the middle, one remedy that worked for me is taking the cable
out and giving it a few smacks on the ground. if you don't use the boat
much then you'll prolly have to buy a new one. UD
