Measuring

A: To know the width area of where you will be mounting your aqua step, measure underneath your add-on platform between the mounting braces. If you have an exhaust in this area, include it in your drawing with the width diameter of the exhaust.

B: To know the depth of your platform, measure all the way to the back of your transom. Note: If your platform is not flat underneath (some have a recession or lip) you need to draw that in diagram B below, also give us the flat area measurement all the way back to the transom.
