I'm a newbie to the boating world,i just picked up a 1996 skeeter everything looks great but the trolling motor will not go. I know there power to it cause when i switch to continous it will run,but only if i give the prop a spin by hand, it will also shut off when commanded. When i switch it manual position i dont get any movement.Wondering if i could get a few tips, it woud be greatly appreciated.
