Have read several complaints about the Ultrex cable.
I've now installed 3 for myself and some friends. Two of them have already broken the hood cover where the cables enter the steering box. IMO its because the hood is thin and brittle and the sheath is stiff.
On one of the units the cables were so twisted inside the sheath there was no way to make it lay on the deck.
There are several replacement covers available that will flex a lot easier. Some have Velcro to make for easy installation. I chose a heavy duty braided sleeve that requires taking every thing loose to install. Was more work, but glad I did. After removing the original cover it was evident why some cables are so twisted.. The steering cables were intertwined with the wires and twisted twice in one direction and once the other. Have not gotten to use it yet but so far I believe it will be worth the effort.
