Overview

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.

Features
  • Drivability: Feel like you’re driving a modern luxury car with the smoothness and ease provided by Digital Throttle and Shift, a Mercury Racing exclusive
  • Torque: The bored 8.6 liter V8 provides unmatched low-end and mid-range torque to get you where you want to go…FAST!
  • Durable: The 540 valve train provides exceptional longevity with limited service intervals to keep you out on the water longer
  • Bling: Polished stainless steel headers give the engine more breathing room and a look that screams high performance
  • Corrosion Resistant: Closed cooling and twin-walled stainless steel headers protect the engine from the corrosive salt water environment
