This is my first boat (2008-Challenger SE-430hp), but for what its worth, it is truly amazing. My wife grew up with lake boats and my dad always had river boats. Being from Northern Alberta, there are a lot of skinny rivers to explore. Mine won't see a river but its the best of both worlds. No props to worry about when the kids are off the back.
I've only had it on 4 different lakes, but it always turns heads and now that I'm comfortable driving it, it does things a 23 1/2ft boat just shouldn't do. Try grabbing reverse at 40-45mph and cranking the wheel over in a stern drive boat! Most of my friends have wake board boats (Mastercraft, etc.) which are very nice inside but they are always impressed with the interior room and the performance of my boat.
The top indicated speed I've been able to get out of it was 57mph with 3 adults and 4 kids, 1/2 a tank of fuel and a slight chop on the lake. Again this was indicated and I don't know how accurate the speedo is. I'll use GPS next summer, as its put away for the winter now.
Two things to remember, these love to carve but you have to be on the throttle. The more power you give it, the harder it turns. And secondly, when you are reversing the boat, you still turn the wheel in the direction you want the front end to travel. It was a bit of a learning curve getting it on and off the trailer, but like anything with some time and patience, you get used to it.
The stock stereo (200W Jensen) leaves something to be desired and will be changed out over the winter (I'm still taking suggestions on this one!), plus an infinity sound system added up top on the tower, plus some lights.
I would also like to have a heater on board, which I guess you can get with the 230 wake. Not sure why I couldn't get it on my boat. The only other complaint I have is accessing the engine bay. You need a second person to pull the release cable so you can pull up the back platform.
I had wanted an all around boat that we could ski/tube/board with as well as throw a line over the bow with my boys while mamma reads a book. I'm very happy with it. Of course this year, they upped the horse power to an available 510! Speaking of, does anyone know if this was just a change in boost? If you'd like to know anything else, feel free to ask.
