My steering cable was froze up in the tilt tube and after freeing it up and cleaning and lubing the tilt tube my steering is kinda stiff so I believe its time for a new steering cable. I have a Morse Cable and there is no replacement, so I will have to replace the helm and cable. What is the best way to go? I have rack and pinion but I've heard some like the rotary better. I'm running a 50 hp so its no speed demon. Thanks for your help.
