Intuitive, Innovative Features

• TORQUEMASTER GEARCASE: The lightweight TorqueMaster gearcase (featured on select V8 models) has a 1.75:1 gear ratio and a robust 1.25-inch-diameter prop shaft designed for semi-surfacing, high-speed applications.
• TRANSIENT SPARK TECHNOLOGY: Transient Spark Technology electronically adjusts the ignition timing of the engine as needed. This subtle, automatic change produces additional torque for faster hole shot and acceleration.
• ADAPTIVE SPEED CONTROL: Adaptive Speed Control maintains a desired rpm regardless of changes in load or conditions without adjustments to the throttle lever position – a first for the outboard industry.
• EXTRA CHARGING POWER: A powerful alternator provides net charging output of 20 amps at idle and 85 amps at wide open throttle. Idle Charge battery-management technology automatically increases idle rpm to boost alternator output and recharge low batteries.
• PERFORMANCE-TUNED EXHAUST: Exhaust tone has been fine-tuned to provide a brawny performance-inspired sound quality that’s unmistakable on the water yet quieter than competing high-output engines.

Pro XS Advantage

• EFFICIENT ALL-AROUND PERFORMANCE: A host of efficiency-enhancing features such as Advanced Range Optimization (ARO), a closed-loop fuel system and a hydrodynamic gearcase optimize fuel economy so you can get more done on every tank.
• SQUEEZING SPEED FROM FUEL: Mercury V8 and V6 Pro XS models transform every drop of fuel into performance to deliver excellent economy at cruising speed and wide-open throttle.
• TOURNAMENT-WINNING TORQUE: More displacement delivers more torque and Transient Spark technology optimizes spark timing to boost that torque during hole shot.
• SMART CHARGING: A powerful alternator provides net charging output of 20 amps at idle and 85 amps at wide open throttle. Idle Charge battery-management technology automatically increases idle rpm to boost alternator output and recharge low batteries.

Pro XS Performance Data

• UNMATCHED POWER AND SPEED: The V8 and V6 Pro XS outboards perform like no other, with a dual overhead cam design that delivers instantaneous throttle response and immediate power.
• SUPERIOR FUEL ECONOMY: Advanced Range Optimization improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly the operator won’t feel or hear it.
• LIGHTWEIGHT HEAVYWEIGHT: 4.6L V8 and 3.4L V6 Pro XS outboards offer a combination of ample torque and less weight – ideal for heavier loaded boats.
