Got a Tracker XT-17 with a 12 v 43 lbs motorguide and thinkin bout goin 24 v with a much largert thrust. Is this a good idea (yes/no) and if so, what would you guys recommend I look at. Old at fishin, but relatively new to crappie boats. All help and harrassment is appreciated. (Sensitivity class week I learned that 'harass' was actually just one word - go figure???)
