Will the EV-150 core pack drive my existing ST5000 plus hydraulic pump. The pump works fine and is already plumbed in so it would avoid the need to re-plumb and bleed the system.
Welcome to the Raymarine Forum mzuralow,
You will need to examine the currently installed autopilot hydraulic pump to determine whether it is a 12VDC Type 1 Hydraulic Pump. If so, then a T704071 Evolution EV-150 Power Pilot Core Pack may be used with the currently installed autopilot hydraulic pump.
