No windshield. I love the wind in the face. Part of the bassboat experience.
To cover the hole in the dash I just bolted a piece of aluminum over the hole and attached the ram mount to it.
Heres how I have it set up. I bolted a piece of stainless to cover the hole from my x28. I painted it black, sealed the edges, and bolted the ram mount on it. Its doesnt flex at all and holds my 997si in place when I tighten down the ram mount.
