Do you have any pics of your boat from the side in the water? Set them on something up towards were you plan to mount...take a pic an compare. Mine are mounted bout 1-2 inches off the water and they are even with water when I sit on them. Some will install to be even when boat just sits in water. I used a floor jack and a level to get my hull level to install square to hull. I also used some 1/4 x 2" aluminum back plates to ensure they are solid as I am bout 240lbs. Post some pics of what you have...boat and steps.
