Re: I'm a tiller guy, not really a wheel guy...
I have never seen hydraulic steering on a sailboat, but my understanding is it is much like the hydraulic steering systems I dealt with way back in my Heavy Duty Mechanic days.
If I am correct, then you essentially have a hydraulic pump attached to the steering wheel which transfers hydraulic oil from one side of a hydraulic ram to the other. If the seals are failing in the pump or there is air in the system it may not be moving as much oil, and therefore it may take more turns lock to lock. 5 turns sounds rather excessive!
Another thought; could it be related to linkage between the hydraulic cylinder and the rudder? Presumably the ram connects to a tiller bar. Can the ram be connected to the tiller closer to the rudder, thus requiring less travel lock to lock?
Of course I could be wrong, and 5 turns could be normal! I'm just throwing ideas out there!
I can't imagine there is much helm feel with hydraulic steering.
