Mercury ProXs V8, 300HP EXLPT EFI DTS Outboard Motor

The Mercury Pro XS V8 engines of 200, 225, 250, and 300 horsepower are built for maximum performance, aimed at competitive anglers and those who seek speed and rapid acceleration. The technical base is a 4.6-liter V8 engine, with an induction system optimized for high RPM power and a specific calibration for sporty performance.

Advanced Range Optimization technology efficiently manages fuel consumption without compromising power, while Adaptive Speed Control maintains steady RPM even under variable load conditions. The electronic multiport fuel injection system (EFI) and Digital Throttle and Shift (DTS) provide instant response and superior operational precision.

Pro XS engines are designed to be lightweight and durable, using a casing design that reduces noise and vibrations. The high-capacity alternator ensures continuous power supply to onboard equipment, and the SmartCraft system allows advanced engine performance monitoring.

With a sporty line and Phantom Black finish, Mercury Pro XS is the ideal choice for those who demand uncompromising performance, whether in competitions or in high-speed fishing adventures.
