![]() Take it to the Limit No outboard gets from zero to wide-open quicker than a Mercury Pro XS, now with V8 4.6-liter and V6 3.4-liter muscle. This is performance that will rocket your rig out of the hole and to the next hot spot in a blur. 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. |

TorqueMaster GearcaseThe 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. |
Adaptive Speed ControlAdaptive 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. |
Performance-Tuned ExhaustExhaust 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. |
Transient Spark TechnologyTransient 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. |
Extra Charging PowerA 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. |
