The 8.6L 540 features a CNC machined cylinder block packed with Mercury Racing designed components 
 
The naturally aspirated engine replaces the veteran 8.2L 525 EFI. Digital throttle and shift provides the operator with an intuitive control experience, including a balanced crankshaft, forged and shot-peened I-beam connecting rods and forged aluminum pistons. A carburized hardened camshaft is used for enhanced durability. Performance cam profiles, combined with larger valves, flow more air through the engine for greater power and torque. Increased displacement, combined with enhanced airflow, results in unprecedented mid-range punch and consistent pull through the engine rpm range. Closed cooling and twin-walled stainless steel headers protect the engine from the corrosive salt water environment
 
The 540 complies with EPA emissions requirements. CARB (California Air Resources Board) emissions compliant models are available upon special request.
