Well don’t but an auto pilot motor. It’s a $200 addition that doesn’t work. What you want is a Minn Kota powerdrive with the Copilot addition. I bought my powerdrive motor online at walmart for $311 plus shipping and taxes. It’s a 40# thrust, plenty for your boat and it has a foot control that pretty much sux. The remote control feature (co-pilot) is the coolest thing ever invented for trolling motors and it can be bought separate for $149 at BPS or Cabelas or Ebay. <<<<Buy an extra remote for it>>>> There $40.
It’s a big investment but let me assure you, you won’t ever regret it. I own two Minn Kotas and have had good service from them both. Shop around you might get a good deal but I couldn’t beat Wally Worlds price when I was shopping. I’ll be buying another on pretty soon.
Should you decide to buy a cheaper motor don’t buy anything but a composite shaft for river fishing. A metal shaft will get bent first time you run up on a shoal in current and jam it in the ground, been there, done that….
