There is a reason that the helm ratio is the same. If the helm turns without a response, then you may have air in the system. Have you checked the fluid level? This needs to be checked regularly, just like the engine oil...
There is no option to change out the helm pump or hydraulic ram for the BayStar, as there is for the more robust SeaStar. The kit comes for an engine of less than 150 hp with 5 turns lock to lock steering.
You need to find out if your helm goes more than 5 turns lock to lock. You could adapt a different pump from SeaStar, but the tubings and fittings are different.
What many of use is a "Suicide" (also known as Brody, necking, steering knob), Edson makes a nice one which clamps on the wheel, and is what I use. For example when backing the boat, I will stand in the isle, looking aft, with left hand on the "knob", and use that to steer. I would not want more sensitive steering...
