I'm new to the skiff world and have purchased a Towee River Master 16 for my local rivers and lakes here in TN. I would like to put a trolling motor on her and was looking at the Minn Kota Power Drive V2. My question is how much thrust should I get? I know what the charts say which would indicate I should be fine with 45lbs since the boat is only 16' and I don't think, all in with boat, motor, people and gear, it would weigh more than 1500lbs, but the guys at BassPro said I should get 55lbs. Any sage advice for a newbie? Thanks for you time!
