Ilmor is MasterCraft’s exclusive partner for recreational marine engines. A Penske Company, Ilmor has more than 30 years experience in automotive racing. Enjoy more time and more fun on the water with the industry’s most responsive, robust and reliable engines.
REAL WORLD RELIABILITY
Ilmor knows how to engineer simplicity and reliability. From fewer hoses and clamps to an engine power distribution module (e-PDM), eliminating the need for physical fuses and allowing resets right from the dash, you'll experience unrivaled reliability. A crank-mounted raw water pump on the 6.0L, 5.3L and 6.2L engines eliminates common failure points, allowing longer time (two seasons/125 hours) between routine impeller servicing.
LEVELED UP WITH MORE LITERS
More liters mean more power, and you'll feel the difference in our 380 horsepower 6.0L MPI engine, standard on the NXT, XT, and ProStar models. The XStar S and X models feature a powerful 430 horsepower 6.2L GDI, and can be upgraded to the Ilmor 6.2L Supercharged engine, with 630 horsepower. For those seeking saltwater, the 5.3L GDI has an efficient closed-cooled aluminum block, running 365 horsepower at higher RPMs giving it outstanding top-end performance.
MEAN AND CLEAN
And consistent with our philosophy of Making Boating Better, Ilmor engines meet the strictest environmental requirements of not just the EPA, but also CARB ultra clean ratings, single/twin BSO certification, and EU-RCD standards. The Ilmor GDI class engine is one of the top 5-star emissions rated gasoline marine engines in the world.
DOUBLE VOLTAGE
Ilmor has incorporated new Mechman alternators offering 180A of peak current output (double the previous generation). So plug in and play loud, knowing your boat’s electrical system has top-of-the-line power.
WORLD-CLASS WARRANTY
Ilmor engines have an unprecedented 7-year, 1,000-hour, factory-backed warranty—the most comprehensive in the towboat industry. This is the gold standard.
