JimmyB,
Welcome aboard. I bought a first boat 2 years ago which is very similar to the boat you are looking at. Mine is a 2005 210 horizon which is the same boat as your 220. They changed their naming system in 2006. I also have the 5.0 gxi with sx outdrive. I love the boat. It has been perfect for my family and I. I use it for water sports 90% of the time. Wakeboarding, water skiiing, slalom skiing, tubing. We have pulled wakeboarders with 10 people on board, 6 adults (5 in boat, one one end of rope) and 4 kids 10 yrs old and younger. The boat performed perfectly. I am a novice wakeboarder, but to me, the wake size is fine. I'm sure that dedicated wakboard boats throw a more sculpted wake; I guess it depends on how you will use it.
Here is a link from Four Winns' website that gives specifications and performance info on the 220 (among others):

As far as power is concerned, I have had absolutely no problems with the 5.0. I'm not running WOT all the time. 98% of the time I'm under 35 mph, so I'm not concerned about hitting 50. I do plan to change out my stainless 3-blade prop for a 5-blade this spring to give a stronger hole shot and better speed control when towing.
We have loved our 210. Great storage. Great layout for my family. I have gotten tons of compliments on the boat from everyone who has come aboard (even other boaters). It was a great choice for me.
