A side story for you. I have a 21 foot Northwest jet boat with a Hamilton 212 pump on it. We had it up at a lake one day with a large group of people with boats. Some of my freinds wanted to water ski behind it. Long story short, when you yell "hit it" behind a jet boat with a standard length rope... you get blasted right out of your ski's ... After we figured out that you need at least 100 ft of rope, it worked fine. However, sking inside the wake feels like sking on gravel or something. I thought about this because the boat has a kicker and had down riggers on it at the time as mentioned in an above post.
