PART THE WATERS AND PUT THE POWER DOWN

Ilmor is MasterCraft’s exclusive partner for recreational marine engines.

Built on decades of high performance innovation that wins Indy Car championships, Ilmor’s engineering team works closely with MasterCraft to design powerful, purpose-built powerplants. Why it matters to you: the most responsive, robust, and reliable engines means more time on the water doing what you love. Welcome to world class.

THE WARRANTY
NOBODY CAN TOUCH

Rest easy knowing Ilmor is relentless when it comes to precision-made, rigorously tested, and continuously improved engines. And backing that trust up, Ilmor engines have an unprecedented seven year, 1000 hour, factory backed warranty—the most comprehensive in the towboat industry. This is the gold standard.

LEVELED UP
WITH MORE LITERS

New for 2020, MasterCraft is boosting the base engines across the board: More liters means more power, and you will feel the difference in our 380 horsepower 6.0L MPI engine, standard on the NXT, XT, and ProStar models. X Series models along with the XStar feature a silky smooth 430 horsepower 6.2L GDI. The torque and gearing ratios are all designed to give you a power curve with tractor-like towing muscle in a boat filled with ballast, but also plenty of glorious top end when you want to open up and blow hats off heads. And for those seeking saltwater, the super tech 5.3L GDI has a close-cooled aluminum block for maximum efficiency, running 365 horsepower at higher RPMs gives it outstanding top end performance, while still pulling wicked holeshots.

REAL WORLD RELIABILITY

The benefit of working with a racecar engine maker is Ilmor knows how to engineer simplicity and reliability. From fewer hoses and clamps, to an engine power distribution module (e-PDM) which eliminates the need for physical fuses and lets you reset, right from the dash. A worry-free crank-mounted raw water pump on the 6.0L, 5.3L, and 6.2L engines eliminates common failure points, and allows longer time (two seasons/125 hours) between routine impeller servicing.

MEAN AND CLEAN

Ilmor produced the first marine engines in the world to exceed the standards of the EPA, the EU, CARB ultra clean ratings, and single/twin BSO certification. Wider band oxygen sensors optimize air-fuel ratio and fuel efficiency, so you are on the water longer between fill ups. All this innovation is better for the planet, and better for anyone behind the boat.

DOUBLE VOLTAGE

With all the modern electronics on board paired with a high output engine, it’s essential to have your power covered. 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.

*When you fuel your MasterCraft boat having an Ilmor engine, please be certain that you do not use a
fuel blend that exceeds 10% ethanol, or which contains any methanol. Doing so could damage your
engine and void your engine warranty.
