Bold new Mercury Racing graphics, emphasizing the horsepower rating and the latest Racing word mark, provide a powerful new look for our classic 250 XS and 300 XS outboards. They continue to show steady demand amongst performance enthusiasts from performance bass to catamaran hulls.  In addition, their combination of high power and torque with ultra-light weight make them excellent for repowering older performance boats. Both models are well proven with documented success as performance leaders in their respective categories.

Record Breaking Speed

 

The 250 XS holds a colorful past. The low-emissions 2-stroke was a game changer the moment it was released. It outperformed competitive 250 horsepower engines in a variety of categories including fuel economy, mid-range acceleration and top speed. The 250 XS also holds an APBA Pro Stock Bass World Kilo Speed Record.

250 XS models come exclusively with the legendary Sport Master gearcase. Designed for lighter weight hulls capable of speeds in excess of 85 mph, the Sport Master features a crescent leading edge housing with low water pickups. This enables the 250 XS to run at elevated transom heights for maximum engine rpm, hydrodynamic efficiency and top-end speeds.

Versatile Performer 

The 300 XS is our most successful 2-stroke consumer performance outboard. Not only does it outperform all competitors at the same horsepower node – it does it no matter what the application.

Models are available in 20-inch, 25-inch and 30-inch mid sections. A custom designed exhaust adapter plate with built-in appendages for mounting after-market steering wing plates enable the 300 XS to be used safely on high-speed multi-engine catamaran and vee-bottom boats. Offshore models come standard with a heavy-duty swivel/clamp bracket assembly and trim cylinder. The race-proven remote mounted trim pump provides a quicker trim-out speed and enhanced durability.

Gearcase Options

A multitude of gearcase options are available for virtually any application. Models fitted with the 20-inch mid-section are available with the Torque Master II and Sport Master gearcases. Both feature purpose-built housings packed with race-proven heavy-duty components. Applications include single-engine bass, flats and bay boats as well as catamaran and vee-bottom sport boats. The Torque Master II is designed for use on heavier hulls that rely on power trim to generate extra lift.

The Torque Master II and Sport Master gearcases are available with 1.62:1 or 1.75:1 gear ratios. The Torque Master II, designed for single engine applications, is available in right-hand rotation only.

New for the 2017 program year is the adaptation of the 1.75:1, Verado 4.8 gearcase. The gearcase, standard on 25” and 30” offshore models, is designed to withstand the rigors of the tough salt water environment and is ideal for performance center consoles. 300 XS models fitted with Verado gearcases are available in right-hand and left-hand rotation.

Performance Propellers

Performance Propeller Manager Scott Reichow has a variety of propellers designed specifically for 250 XS and 300 XS applications. Popular performance props include the Pro Max, Lightning E.T., Bravo I XS, Bravo I OC.

The low emissions 2-stroke 250 XS and 300 XS outboards continue to prove their durability and reliability. Both are backed with a two-year standard factory warranty with three years of optional MPP (Mercury Product Protection) coverage available.
