I have a 25 ft Sportcraft with a 5.0 Volvo/penta outdrive and power steering..5 years ago I put a raymarine sportpilot on it ..the drive motor mounts on your steering wheel,came with compass,computer and control head..i installed it myself,not too bad ....I got it from Raymarine factory outlet store online for around 1500 bucks...you can call them and they will tell you exactly what you need..mine is a X-5 but they might have something newer now..mine works very good and I haven't had any trouble with it....good luck
