Pro XS 175hp

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. 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. 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. 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. 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. 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. 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. 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.
