is the LQ9 engine needed for the 05 Xstar?

Hi guys,

I'm in the process of deciding between either an 05 X2 or an 05 Xstar. What I'm wondering about is whether or not I would need the LQ9 in the Xstar or if the MCX would be enough for the boat. Either way, I think I would at least get the MCX for either boat just wasn't too sure about the LQ9. Any thoughts or reccomendations?

thanks
