New member here. I have a Wards Sea King 510 12v trolling motor. A neighbor gave it to me along with a small sail boat that is now gone. I never used it and now that I sold the small boat, I would like to sell this trolling motor. I hooked it up to my mower battery and put the motor in a bucket of water to test the function. It appears to work fine. It has a twist throttle control. I don't have a battery to sell with it so the price is just for the trolling motor. It has the boat mount attached to it. Any idea as to how much I should ask for it? I want to sell it face to face so i'll probably list it up on craigslist but I have no idea how much its worth.
