Starting in 2010 MasterCraft Wakeboard Boats would be offered with the ILMOR 5.7-liter, ILMOR 6.0-liter, and ILMOR 6.2-liter motor option. By 2012 ILMOR has become the exclusive motor supplier for the company. When MasterCraft started to build the all new 2012 X-Star they knew more power would be needed and worked with ILMOR to develop a monster 7.4-liter motor. The 2013 Next Generation X-Star does not disappoint with a jaw dropping 522HP. ILMOR did not only help MasterCraft increase raw power but they have also allowed riders to add more ballast without having to worry about problems with the boat not being able to plane out.
Most MasterCraft X Series boats come from the factory equipped with the OJ 522 14.75x15.5 prop. From wakeboarding, wakesurfing, or just cruising across the lake this prop will do everything equally well. When our customers are running more than 2000 lbs. of ballast or are riding above 3000 feet in elevation we would want to consider lowering the pitch. By decreasing the pitch there will be a more efficient power transfer to the water. Recently a lot of customers have been inquiring about upgrading to an OJ 5 blade prop. We offer two options for the spline shaft on MasterCraft Boats. For X Series boats with the small block motors the OJ 5 Blade 1936-2 is the way to go. If you have a newer MasterCraft with an ILMOR big block motor the OJ 5 Blade 1936-4 is the kittens' mittens delivering unparalleled performance.MasterCraft Propeller Guide
