Pro XS 175-300HP
A New Era in Performance
Mercury Pro XS® outboard motors are designed for boat owners who demand the highest level of performance—competitive tournament anglers and speedboat enthusiasts who crave speed and acceleration. Special components and settings deliver the highest level of performance in all Pro XS models, allowing you to push the limits.
TorqueMaster Transmission
The Lightweight TorqueMaster transmission (available on select V8 models) features a 1.75:1 gear ratio and a sturdy 1.25-inch diameter propeller shaft designed for half-surface, high-speed applications.
Adaptive Cruise Control
Adaptive Speed Control maintains the desired revolutions per minute (rpm) without requiring any adjustment to the throttle lever, regardless of changes in load or conditions—a first in the outboard motor industry.
Performance-tuned exhaust
The exhaust tone has been finely tuned to deliver a powerful, performance-inspired sound that is noticeable in the water, yet offers a smoother sound quality than competing high-output engines.
Industry-Specific Battery Management Technology
When the battery voltage is low, the motors automatically increase the idle speed to boost the alternator and charge the batteries to the appropriate level. This protects the batteries and electrical devices from draining during fishing.
Large Amount of Load Output
FourStroke models feature a powerful alternator that provides 20 amps of net charging output at idle and 30 amps at maximum speed.
Unrivaled Power and Speed
Superior Fuel Economy
Advanced Range Optimization increases fuel savings at cruising speed by automatically adjusting refueling so smoothly that the operator will not feel or hear it.

Pro XS Advantages
Top-Level Performance
No outboard motor can accelerate from zero to high speed as quickly as the Mercury Pro XS with its 4.6L V8 and 3.4L V6 engines. This performance will propel your equipment forward quickly and get you to your next destination in no time.
Tournament-Winning Torque
More displacement brings more torque, and Transient Spark technology optimizes ignition timing to increase this torque at startup.
Converting Fuel into Performance
The Mercury V8 and V6 Pro XS models convert every drop of fuel into performance, providing excellent fuel economy at cruising speed and maximum speed.
Smart Charging
The powerful alternator provides a net charge output of 20 amps at idle and 85 amps at maximum speed. At idle, the charge battery management system automatically increases the idle speed to boost the alternator output and recharge low-level batteries.
