Mercury Pro XS® outboards possess the ideal combination of lightweight engineering and high displacement to maximize power, torque and overall performance. Whether running compact bass rigs, flats skiffs or multi-species boats – on freshwater or saltwater – Pro XS is unmatched muscle for midsized boats.
 

Mercury Four Stroke outboards offer everything you need for a boating experience that exceeds expectations: Power. Speed. Efficiency. Reliability. Low cost of operation and ownership. And the kind of quiet confidence that comes when you know everything is working as it should.

The main difference is that the Mercury 115 Pro XS is a higher-performance version of the standard 115 FourStroke. The Pro XS is tuned for better acceleration (hole shot) and higher top speeds by having a higher redline (\(6,300\) RPM vs. \(6,000\) RPM) and more aggressive engine mapping. It also includes a higher-output charging system that can increase idle speed to maintain battery charge. 

Smooth & Quiet

Optimized from the cowl to the mounts to minimize noise and vibration, Pro XS outboards won’t wear you out on long runs to faraway fishing holes.

Light & Powerful

Mercury 115 and 150hp Pro XS outboards boast the highest displacement and lowest weight among high-output engines in their class, for unmatched hole shot on a wide variety of boats.

Quick & Fast

No other competitive outboard can match the top speed and acceleration of a Mercury 115 or 150hp Pro XS outboard.

Intuitive, Innovative Features

Performance-Inspired Gearcase

The 150hp Pro XS gearcase is optimized for fast hole shots, top speeds and enhanced control at wide-open throttle. The 115hp engine can be paired with the Command Thrust (CT) gearcase. It’s designed to turn a larger pop, providing greater acceleration, better handling, awesome maneuverability and superior control.

Tiller Handle

If you run a tiller boat, you can still enjoy the speed and exhilaration of a performance-tuned Pro XS engine. The tiller handles for both the 115 and 150hp engines are available with integrated Troll Control rpm-based speed control. The Big Tiller, available for the 150hp engine, can be paired with Mercury power steering.

Transient Spark Technology

Transient Spark technology (150hp model) electronically adjusts spark plug timing to optimize low-end power. The result is performance you can feel – greater torque, faster hole shots and sensational acceleration.


IMPORTANT NOTE:

All new Mercury outboards are required by Mercury Marine to have a certified technician PDI (Pre Delivery Inspection) the engine after installation to have the warranty activated.  This not only ensures the product is set up to the manufacturer's specifications but also allows us as a dealer to ensure that the installation was done correctly.  If the engine is purchased and installed by us, it is standard procedure for us to perform the PDI.  If the engine is purchased and is installed by the consumer or non-dealer, the engine must be taken to another authorized Mercury dealer or to us to be inspected and registered to have the warranty activated.
There will be a small fee associated with the purchase of the engine if we are not doing the installation and if the consumer decides to have us register it.
