Auto-pilot questions

[FishingFool34]

So im looking at buying a larger boat This year. A couple boats I have come across have autopilot systems in them (raymarine ev100 has shown up on 2 of them). I don’t know much about auto pilot systems but I do know big carbed V8 I/O motors aren’t good on fuel. If I wanted to install a kicker on a boat with autopilot is it as simple as connecting the kicker to the main via tie-bar system and the autopilot will basically steer the kicker? If the boat has hydraulic steering will the AP even work with the main motor off?
