Like C-B said, post a pic of the seat hole(don't be imagining anything) for the post, there are a few variations. Transducers cost anywhere from $45-80 depending on model and features, again we need the Fishfinder brand name and model # to send you in the right direction. If you're towing the boat right now, motor down, full speed ahead, make like a snowblower...just kiddin. Tilt up, lay to one side, tie off the steering at the front. There could be a tilt/lock mechanism on the motor(right side from rear) to prevent the motor slamming back down. Some guys will say, motor down, I don't like leaving prop marks on the roads.
