Re: steering question
There is nothing wrong with cable/pulley steering if installed correctly. First, the geometry must be right, but that is another question. Second, like any other system, the parts must be in good condition. Thirdly, the dangerous part: The pulley straps should be through-bolted to the hull, no wood screws. And there were some pulleys made with brass hooks that were just peened over where they go through the U-strap on the pulley. Sometimes those things would pull out. Not good. Lastly, the cable itself: If it is discolored in spots (wire inside is rusted), or the plastic is disintegrating, replace the cable. You can get it at hardware stores or Home Depot.
Actually, that motor was designed for cable/pulley steering. You CAN retrofit with a Teleflex push-pull system, but that itself has fit-up problems. If it were mine, I'd stay with cable/pulley.
