The panther t4 or t5 utilizes the threaded tilt tube on your outboard/kicker. There are no holes too drill just screw it on and attach the steering adapter to the front of the outboard frame, a very simple and straightforward installation. I know several people who have the t4 and are happy with them. You must have a threaded tilt tube for them to work though, I suggest searching panther electro steer and view the videos to find the unit that would best work for you. The T5 is made for a more confined space.
