Opinions on the wakesetter 247 rx?

Our local dealer has a 2008 247 rx with 200 hours and is priced pretty well. We like the layout and the boat is in great condition, the only concern is the surf wake. We test drove a 23 LSV with surf gate, and it was an awesome wake. We were told that the 247 would obviously be not as good due to the center mounted engine and no surf gate. But, how bad will it be? Is it going to be surf-able with no rope? We just started surfing but would like to get into it more so I just wanted to make sure that the wake is good enough with this boat. Also, it has the hydrallic powerwedge and a bow, center, and 2 rear ballasts. Oh, last thing, if the wake is indeed pretty poor, are there any aftermarket surf gates you can get? If not I saw a couple homemade ones which saw some good results.
