I was a Minn Kota guy up until a few years ago and bought a boat with a Garmin Force and after selling that boat I didn't even consider another trolling motor for my current boat. Brushless is the only way to go especially if you do any type of trolling and Garmin's customer service has always been top notch the couple times that I've called them and it's 24 or 36 volts just depends on how you want to hook it up.
