Roll over a callout or click the arrows to rotate the engine.

Cooling System

Featuring a belt-driven raw water pump, allowing a better match of pump speed to engine speed, increasing cooling effectiveness and equipment longevity.

Easily-Accessible Service Area

The oil filter, fuses, relays and circuit breakers are designed and positioned for easy access.

EControls ECU

Supports a wide range of speed control options, and offers precise control of fuel delivery, ignition, and drive by wire throttle, as well as excellent idle quality. It also integrates seamlessly with ZeroOff, Perfect Pass, and MasterCraft cruise functions.

Exhaust Manifold

Uniquely designed cast iron, water cooled and catalyst equipped, thermostatically controlled exhaust manifolds provide superior corrosion resistance and durability.

Intake Manifold and Plenum

The intake manifold is unique to marine engine design, tuned by Ilmor to tailor the power/torque curve for maximum performance.

Oil Cooling System

The “tandem” engine and transmission oil cooler provides increased performance at high loads for extended intervals.

Remote Mount Thermostat

The Ilmor-designed remote thermostat keeps the exhaust manifolds warm, reducing catalyst damaging condensation.

“True” Serpentine Auto- tensioning Belt System

The serpentine belt system is designed to increase overall efficiency and simplify serviceability.

Variable Valve Timing

The dual-equal hydraulic cam phaser adjusts camshaft timing at same rate for intake and exhaust valves; advancing cam timing for low end torque and retarding cam timing for high RPM horsepower (exclusive to the 6.0L).
