Do you have a jack plate? If so, most are mounting there. If you mount on the transom just make sure you follow the instructions and get it the proper distance from the prop and level. If its not level, then the side that is high will show up dark on the display. Also make sure it is below the water line but not too low or you could rip it off. I would definitely check out the Side Imaging Forum. There are several installation pictures there. Side Imaging Forum Heres the link to a lot of installation pictures.
