From the website:
"There are two kinds of boaters. Those who have had steering problems and those who will.
Cable steering failures are rarely caused by the front part of the cable. Unless a cable has a "suicide bend" in it, failures at the helm end are caused by strain created at the aft end, where contaminants can enter. Even with a stainless steel tilt tube, the carbon steel cable begins to rust and expand inside the sheath. As friction increases, more pressure is placed on the entire cable, including the gearbox at the helm."
