It came with a used boat I bought this spring, it was still in the box. Finally got a chance to hook it up and use it yesterday, as soon as I connect to the battery the prop starts spinning. Doesn't matter if the tiller selector is "off" "forward" or "reverse" It spins the same direction and at a constant slow speed regardless of the speed or direction selected.
Any ideas on what to check? I called MinnKota and they said take it to a service center and pay to have it looked at since I didn't buy it myself.
