Normal
My short shaft jet outboard sits 2-1/2" above the transom to tuck properly into the jet tunnel. I've just run most of my boats the way they were set up when I got them so I never paid close attention. With this jet tunnel boat, the previous owner had a prop motor on it which I sold when I got the jet. I had to make multiple adjustments to get the height for best performance and least amount of spray back. I also had to add transom wedges to get rid of porpoising. With a clamp on motor, I'm not sure I would want it mounted too high, but I've never had a clamp on so I might just be over cautious.
