Raytheon 5000 was my choice
I installed a Raytheon 5000 unit on my dash but I installed a Winlock drive in the pedistall because it has more power. The motor is large enough to hold the ship on course in heavy weather. The 5000 is hocked up to the rest of the instruments (wind direction and speed, depth, radar, boat speed and GPS). If I want, I can sail the wind direction or the GPS waypoints. Winlock is sold by PYI who sells Max Props.
