Description

The 540 features a CNC machined cylinder block packed with Mercury Racing designed components, 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. The 540 complies with EPA emissions requirements. CARB (California Air Resources Board) emissions compliant models are available upon special request.
