Installation was quick and easy. It works exactly how it is advertised. Slowed me down to perfect trolling speed and the speed is adjustable with the throttle. The only suggestion I would have is to put an indicator tab on the plate to make it easier to see when the plate is up or down. With my I/O it is difficult to see the plate with my swim platform on the back of the boat. I will probably put a small rod on the plate and color the end of it to be sure the plate is horizontal before moving the boat.
