Winning acceleration

No outboard gets from zero to wide-open quicker than a Mercury Pro XS, now with V-8 4.6-liter and V-6 3.4-liter muscle. This is a performance that will rocket your rig out of the hole and to the next hot spot in record time. These Pro XS models feature generous displacement in a performance-tuned powerhead with a deep-breathing double-overhead-cam design and long-runner intake tract that delivers instant throttle response at any speed.

More displacement delivers more torque, and new Transient Spark technology optimizes spark timing to boost that torque during hole shot with a 1.75:1 gear ratio and a robust 3.2-centimeter-diameter prop shaft is designed for semi-surfacing, high-speed
applications. Specific performance calibration takes rpm to 6200 at wide-open throttle for more flexible prop selection.
Squeezing speed from fuel
Mercury V-8 and V-6 Pro XS models transform every drop of fuel into performance to deliver excellent economy at cruising speed and wide-open throttle. Advanced Range Optimization (ARO) calibration utilizes closed-loop fuel control to precisely adjust the fuel mixture and deliver the best possible efficiency
