With a rack and pinion your steering
ratio is not adjustable. In automotive rack and pinions we can build in a non linear ratio across the rack. That is one of the key reasons they're universal in cars now. I havent seen any marine
rack and pinions that are non linear.
You might like to try varying hydraulic displacement
, not pressure.
You don't mention what brand or model hydraulic steering
you have. It might be cheaper and simpler to start with a variable displacement steering
pump. That way you can vary the effective ratio from lock to lock. There will be a sweet spot in terms of ratio that you are looking for.
