ST 5000 updrade to EV 100 T70154

The HC5345 has a RAM capacity of 8.34 Cu/In, which is on the high end of the EV-100 system. Being on the high end of capacity, I always recommend going to the next higher capacity system because of operating the autopilot in heavy seas and longer life. This autopilot would be the Type 1 hydraulic, EV-200. You have supplied the ST5000+ control unit information but nothing on the drive used in the system. I am assuming it is a Type 1 pump, M81120/M81190, please advise.
