fester,Like Larry S., I too have installed hydraulic steering on a high-horsepower engine...it's wonderful. JimH and LHG have prepared an excellent reference article, and you should check it out.
However, no steering system can correct or overcome problems with the engine's ability to "turn." You need to be sure your engine can move freely. Simply disconnect the tiller arm connector from the steering cable. With the engine in an upright (running) position, you should be able to easily swing the engine from side to side, without resistance, binding or other "catches." If you cannot, that problem has to be addressed first. If you can, then installation of a new system can proceed. I'm concerned about what your dealer is telling you could be a $1k repair. It's difficult to imagine what that could be.
Folks tend to think that because steering cables are made of corrosion resistant materials they'll last forever; they don't. And most should be replaced much more frequently than they are. Over time the degradation in performance is gradual, but one day you notice it's taking a pair of "come-alongs" and superman to turn your wheel.
Both hydraulic and cable systems are built to standards that allow them to be installed on any motor you should select in the future. Too, standard, straightforward installations should not require expensive adaptors, modifications, parts etc.; so beware of the salesman/installer who tells you so.
If you choose cable, do get the 4.2, nfb system. If hydraulic is feasible for you, get it...you will never regret it. Generally speaking (I don't know your skill/tool levels) you should be able to install either of these. Mind Larry's advice above and read instructions several times before begining, and cut-and-paste his caveat on "patience." Stick this caveat on your forehead.
Most importantly, we have to remember that these systems are not maintenance free. They require regular inspection and preventative maintenance.
