Re: frozen steering
Unless that cable has been changed it is most likely time. Oil, grease, etc. (never recommended for steering or any other cables) at best will just slightly prolong the use of said cable by lubing the worn and damaged spots inside.
Well, Mine was 2 years old when it jammed up, and replace was several hundred dollars. (Dual NFB) The cleaning and oiling restored it to new, and now, 2 years later, you can still turn the helm with one finger. The cable will fail for one of 3 reasons. Lack of lubrication, contamination, and jacket failure. Pressure cleaning and lubrication will repair the first 2. Proper maintenance will then prolong the life of the repair.
I removed and chitcanned the grease zerk on the front steering rod tube. That helps a lot.
BTW, the guys over on Scream and Fly mostly drive boats that will eject you, sometimes
through real hard boat structure, if the steering fails at speed.
On replacement. Usually you have to swing the engine from a sky hook of some kind to get the cables out of the tubes. You can then usually pull them out from the helm end, pulling in a rope at the same time. New cables then are pulled in from the helm to the stern, hooked up, and the engine re-mounted. Use the proper lifting eye on the engine to avoid damage or injury.
If it's an original Teleflex dual cable (likely) the cables are no longer available. You then have to replace the entire system, about $500.
hope it helps
