So trick worm witch place did you get it from Walmart or Bass Pro I just recently purchased an Ozark Trail model ET 44 and it came with extra prop and I was thinking the same thing what good is a prop without a nut also I see why they give you an extra prop they are made out of plastic where is Minn Kota feels more like a composite resin now the tightening tool on the Bass Pro site looks more like the tightening tool that came with my Ozark Trail which is I believe like everybody is saying is a rebranded MotorGuide. pictures are of the two kits and my tightening tool.
Here's mine it looks more like the one at Bass Pro
