The All-New Ilmor Marine MV8 7.4 L

Ilmor Marine MV8 7.4 LAfter successfully launching the Ilmor Marine MV8 engine line in 2010 the company began to look ahead for the next exciting project. Our team of engineers wanted to harness, calibrate and package more power and torque to create the largest wakes ever seen on a water sports boat. They wanted the engine to produce High-Performance horsepower as well offering low emissions.

Most importantly, it had to be durable, reliable, and fuel efficient like the existing engine line. Decades of successful automotive race engine development and production, as well as nearly ten years of High-Performance marine drivetrain design, made them uniquely suited to take on this challenge. After months of design, development, and vigorous testing, Ilmor had the answer: the 522 horsepower MV8 7.4 L – the most powerful catalyzed production marine engine available today.

The MV8 7.4L is entirely unique to the water sports world. Every component was manufactured using superior materials, like forged steel, for long-term durability. During development, engines were rigorously durability tested both in boats by MasterCraft’s professional athletes, and on dynamometers to ensure performance reliability.

The company also chose to apply variable valve timing, unusual in engines over 500 hp, 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, 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 a game-changing 7.4 L engine that produces monster wakes and huge power in an incredibly reliable package.

The 7.4 L is available in limited MasterCraft models. For more information about the MV8 7.4 L, including technicial specifications, click here.
