Pro XS 175 - 300hp

A New Era in Performance

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.

Intuitive, Innovative Features

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.

Automatic Two-Speed Transmission

The two-speed transmission makes easy work of transferring 600hp to the gearcase. It doles out maximum torque and acceleration in first gear then silently shifts to second for efficient cruising and thrilling top speed. No shift clunk. No limitations. Only smooth, impressive power.

Independent, Steerable Gearcase

Electro-hydraulic controls allow the steerable gearcase to react instantly to driver commands. With no movement from the engine above water, there are no distractions – only precise maneuverability around docks and smooth, effortless handling in open water.

Contra-Rotating Propellers

A new series of dual props were expertly crafted to harness the full potential of 600hp. Designed to run in a contra-rotating configuration, the new propellers power the boat on plane swiftly and efficiently, while delivering exceptional handling and fuel economy at midrange speeds.

Exceptionally Smooth & Quiet

A more rugged, more refined next-generation Advanced MidSection (AMS) mounting system cradles the powerhead to isolate noise and vibration, while careful tuning dampens induction sounds and nearly eliminates injection noise. 600hp never sounded so quiet.

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 Optimisation improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly the operator won’t feel or hear it.

Superior Fuel Economy

4.6L V8 and 3.4L V6 Pro XS outboards offer a combination of ample torque and less weight – ideal for heavier loaded boats.
