Ballast: The stock ballast is 1,000 pounds — 250 in each rear tank and 500 in the center. Recreational wakeboarders will be comfortable with the mellow, rounded wake at this setting. To really serve up "the meat," it's essential to have the 14x14.25 OJ propeller and biggest engine upgrade (8-liter). We also notice a lot more weight added when we're in the boat judging the Pro Wakeboard Tour, or out riding with Rusty Malinoski. Then the MasterCraft X-Star delivers what many riders agree as the best wakeboarding wake and double up in the world. It's a very mellow, yet meaty ramp that makes you wait on all of your moves, delivering a very consistent and comfortable pop. The MasterCraft X-Star is also the flagship for the most progressive double up contest in the history of wakeboarding, Parks Bonifay's Double Or Nothing.
