Without sounding rude, can I ask what the purpose of the splash guard is? Is it to keep water from coming over the transom when letting off the gas or something? I don't know on your boat, but if I had that thing installed on my Rogers I wouldn't be able to get to the water filter, msd box or diverter pump which are all located on the inside of the transom.
Without one on mine, I'd have undoubtedly sunk it a few times now.........

Most boats, like Moo, have a lot more free board, (Hull sticking out of the water on the back half) and the design on the transom gets it up and over your own wake if you lift and stop. Never had a problem with water over the transom or sides if you spin out or lift, etc.
Pickle? Forget it! Wakes from wakeboard boats, stopping suddenly or stalling, and my own stupidity have almost swamped it a few times as it is! That splashguard is a life saver on that thing! I also see why this thing has 2 bilge pumps! They are only mounted to the inside edge of the gunnels/transom, should still have access to all the stuff on your transom.
