MERCURY
 
optimaxproxs175-1.jpg
PRO XS - the strongest family of direct injected engines in the industry.
OptiMax Pro XS blows away the competition when it comes to power, durability, performance and fuel efficiency. The new 200 and 115 Pro XS models deliver better speed and greater acceleration.

IMPROVED DURABILITY AND RESPONSE
Only OptiMax Pro XS features Carbon Fiber Reeds to control airflow into the engine crankcase. Carbon fiber reeds produce improved performance and efficiency because they are more durable and responsive than stainless steel or other fiber materials.

TOUGHER GEARCASE
The durable Torque Master Gearcase (225/250 Pro XS) features a heavy-duty propshaft and Mercury-patented dual water pickups on the front end of the torpedo for a constant flow of cooling water. The asymmetrical skeg delivers superior handling by countering the torque created by prop rotation.
 
MORE HORSEPOWER
The Pro XS offers a Higher Wide-Open-Throttle RPM Operating Range, giving you more propeller options to maximize the performance of your boat.

PRECISE HIGH-SPEED HANDLING
Controlled handling at all speeds is essential, so we outfitted the 250 Pro XS with Solid Billet Aluminum Mounts to keep the engine from turning or twisting under high torque (20-inch models only).

EXCELLENT EFFICIENCY
Exclusive Dome-Shaped Pistons efficiently direct the fuel/air charge to the spark plug, producing excellent running quality, fuel economy and low emissions.

SUPERIOR PERFORMANCE
The OptiMax Two-Stage Direct Injection System produces consistent performance and unmatched throttle response by providing a constant supply of atomized fuel and air.
