The problem started with the steering frozen and the engine locked in position. I removed the idler arm connecting the 90 HP Mercury engine to the steering rod eyelet. The engine moved freely. I proceeded to connect a puller to the steering rod eyelet to see if I could free the steering rod and cable without success. The steering rod was frozen in position. After removing the steering cable nut from the tube the eyelet end of the steering rod remained in place and the steering rod itself extended about 10 inches before hitting a solid metal dead end and will not extract from the steering tube. I have held the rod with vise grips and jerked against the rod without success thinking it was corroded. The cable was supposedly replaced by the original owner about 3 years ago without incident. This is my first boat and motor so please advise.
