Take my picture for example. Thx

No problem. A SeaStar Hydraulic helm is simply a pump pushing fluid to a reacting ram. The bigger the pump in volume per turn equals more fluid to move the ram farther per turn. Lower volume out put helm like a 1.4 or 1.7 take more turns and less leverage to turn the motor. Higher volume pumps like a 2.4 push more fluid per turn and require less rotations of the wheel to move the ram just as far. If you are moving more fluid per turn the energy or effort needed to turn the wheel is increased and you will likely need the bigger diameter wheel to compensate for the effort unless you are Chuck Norris. Chuck Norris's boat doesn't have a helm.... If he wants to turn he just spins the earth until he is on course.
