I have a World Cat 230cc 2018 It has a SeaStar HC 5343 Ram I caled Sea star and they said it has 8.13 cu. in. (133.2cc) will a ev100 work with it? I see two diff things one says up to 150cc and another says 110cc. I think the ev100 was upgraded to 150cc. TY for your help
Welcome to the Raymarine Forum boatman2,

here to view a FAQ addressing this subject. As indicated therein, an hydraulic ram having a cubic capacity of 8.13 cu. in. would require a Type 1 Hydraulic Pump, which in turn would be interfaced to an ACU150 (for boats having a 12 VDC power distribution system) or an ACU200 (for boats having either a 12 VDC or a 24 VDC power distribution system). The T70330 EV-150 Hydraulic autopilot combines p70Rs, EV1 Sensor Core, ACU-150, Type 1 Hydraulic Pump, and Evolution Cable Kit within a single package. Similarly, the T70157 EV-200 Hydraulic autopilot combines p70Rs, EV1 Sensor Core, ACU-150, Type 1 Hydraulic Pump, and Evolution Cable Kit within a single package.
