“The unveiling of these powerful, high-horsepower Pro XS models culminates a process we began in 2016 to comprehensively elevate the entire Pro XS brand with engineering that delivers higher performance, better fuel economy, uncompromising reliability and durability in a light-weight four-stroke design,” said John Buelow, Mercury Marine vice president of global category management. “We now have a complete family of top-performing Pro XS outboards from 115-300hp that competitive anglers will love.”

“I need to go fast and maximize my time out on the water,” said Kevin VanDam, Four-Time Bassmaster Classic Champion. “These engines are so light, fast and quiet – it’s stunning. Mercury has raised the bar with every aspect of this engine


New V-6 3.4L 175hp Pro XS

The new 175hp Pro XS model is built on the NMMA Innovation Award winning 3.4-liter V-6 platform that Mercury introduced at the Miami International Boat Show in February. Upholding the Pro XS hallmark of ultimate performance, Mercury engineered this large displacement engine to deliver higher maximum RPM at full throttle, while retaining the Mercury V-6 platform’s peerless light weight (470lbs for the 175 Pro XS) and fuel economy. This is the perfect engine for the angler who wants to get to the fish fast.

New V-8 4.6L 200-300hp Pro XS

The new 200-300hp Pro XS models are built on Mercury’s new V-8 engine platform and boast a class-leading 4.6L powerhead that delivers phenomenal torque while weighing just 505 pounds. During performance testing, the 250hp Pro XS set new standards for high performance, outpacing the leading competitor by 20 percent for heavy load 0-20 mph acceleration and one mile-per-hour faster top speed all while delivering up to 16 percent better fuel economy at cruise. This means unrivaled performance for the elite fisherman and an engine that provides the confidence necessary to ensure a championship weekend of fishing.

The 200-300hp Pro XS models also feature a robust 1.25-inch diameter prop shaft and are available with a next-generation Torque Master gearcase that offers a 1.75:1 gear ratio and low-water pickups on the nosecone for added mounting and trimming flexibility.
