Then of course, you have to walk the fine line between thrust and cavitation! Too shallow a pitch and the prop will rip through the water and not gain any forward traction for the force applied. It's like everything else, it's a trade-off between holeshot and top speed. As previously mentioned, whale-tails make a huge difference in holeshot at the expense of top-end. They also help make slightly smoother wake for wakeboarders and the like.
