The new base of the Elite series the holes if centered on the ram mount plate are not even on the plate. So if i were slide the lowrance mount either foward or backward the best i can do is two of the 4 holes to hit the ram mounting plate. The bolt pattern of the lowrance bracket is in a square, while everything else in the world is a rectangle.

Did that make sence? I will at work make an adapter plate, it was an inconvience that i did not anticipate.
