i have robalo with twin 150's. i bought used. it has a hynautic steering system with seperate reservoir. i noticed after fishing all day that the pressure in the reservoir had bled down to 0psi. steering still worked fine. i found a leak in the shrader valve on top of reservoir. here is my question. i thought this system would not work without pressure. if it does work then what is the purpose of pressurizing the system? other than that it has worked fine since i bought it.
thanks
