Unscrew throttle knob, sell boat, replace with boat with larger engine. Sorry. But modding the MCX for more power is going to be crazy expensive and probably impossible due to software restrictions. The advertised hp is supposedly a little on the high side. And by "a little," I mean a lot.
But as mentioned above, repropping is probably your best bet in your current setup.
