MasterCraft and Ilmor Marine Unveil All-New High Performance 7.4L

September 15, 2011

Vonore, TN – On the heels of the 2012 X-Star launch, MasterCraft and Ilmor jointly announce the official release of Ilmor Marine’s latest power plant, the MV8 7.4L.  After successfully launching the Ilmor Marine MV8 line in 2010, Ilmor’s team of engineers was challenged by MasterCraft to develop the next revolutionary engine.  The result?  The high-performance 522 horsepower MV8 7.4L -  the most powerful catalyzed production marine engine available today that also offers low emissions with the durability, reliability, and fuel efficiency of the existing MV8 line.

Decades of successful automotive race engine development and production, as well as nearly ten years of High-Performance marine drivetrain design, made Ilmor uniquely suited to take on this challenge.   The MV8 7.4L is entirely unique to the water sports world.   Every component is manufactured using superior materials, like forged steel, for long-term durability.  During development, engines were rigorously durability tested both on dynamometers to ensure performance reliability and in boats by MasterCraft’s professional athletes. 

Travis Moye, the famed wakeboard tournament driver and owner of the Boarding School, is completely sold on the MV8 7.4L.  “I have been running the 7.4L Ilmor all summer and I have been blown away by the pure power of it,” says Moye.  “But, more than the power, I have been amazed by the efficiency. Whether unweighted or fully ballasted, I am running such low rpm's that I have noticed a huge improvement in gas consumption. Anyone who says a performance block isn't the way to go hasn't used this one.”

Ilmor also chose to apply variable valve timing, unusual in engines over 500hp, for overall enhanced performance, providing increased lower end torque and high RPM horsepower. Additionally, the 87-octane compatible, naturally-aspirated engine architecture causes less wear-and-tear on internal engine parts in a fuel-efficient package.

Though not required for emissions compliance, Ilmor elected to deploy an exhaust system equipped with three-stage catalysts on the MV8 7.4L.  In fact, the engine produces nearly 70% lower Carbon Monoxide emissions than engines of comparable size and purpose, a major benefit to boarders and surfers behind the boat. 

Finally, Ilmor is all about the details.  The MV8 7.4L engine is hand-built in the same shop and to the same standards as the racecar engines which have won over 250 IndyCar races and 17 Indy 500s.  The result is the game-changing MV8 7.4L engine that will provide huge muscle in an incredibly reliable package and will confidently power MasterCraft boats no matter how much weight aspiring wakeboarders want to throw at it.
