Mercury Pro XS® outboards are engineered for those boaters who demand ultimate performance – anglers competing on the highly competitive tournament trails and powerboaters who simply crave speed and acceleration. Exclusive components and tuning extract every ounce of performance from each Pro XS model so you can take it to the limit.
Pro XS Advantage
Ultimate Performance: No outboard gets from zero to wide-open quicker than a Mercury Pro XS with 4.6L V8 and 3.4L V6 muscle. This is performance that will rocket your rig out of the hole and to the next hot spot in an instant.
Tournament-Winning Torque: More displacement delivers more torque and Transient Spark technology optimizes spark timing to boost that torque during hole shot.
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.
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.
TUNED TO PERFORM
On freshwater or saltwater – compact bass rigs or flats1 skiffs, pontoons or multi-species boats – four-cylinder Mercury Pro XS models are tuned to take mid-size boats to the limit. Engine controls are calibrated for stronger hole shot and higher rpm. Stiffer high-performance motor mounts on the 150 deliver better highspeed handling. It’s the look and performance of a champion, with bold Pro XS graphics.
The lowest weight and highest displacement in the category contribute to unmatched hole shot on a wide variety of boats. The 150 Pro XS features new Transient Spark technology to optimize spark timing and boost hole shot torque, as well as a higher gear ratio that transmits more torque to the prop shaft.
Intuitive, Innovative Features
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.
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.
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.
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.
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.
