Incredible power, combined with light weight, gives you mind-blowing performance. Mercury's new 115hp Pro XS FourStroke redefines outboard performance.

Choice of Champions.

Pro XS is the best-selling tournament fishing outboard in the world, and has powered more competitive anglers to victory than any other engine. Run with the same confidence professional tournament anglers have – trust Pro XS.

Keeps your battery charged.

The Idle Charge feature monitors your battery’s voltage state, and will increase the engine rpm in order to provide up to 48% more battery charging at idle. This supports the greater power demands of today’s sophisticated marine electronics and accessories, letting boaters and anglers safely stay out on the water longer.

Performance.

Incredible power, combined with light weight, gives you mind-blowing performance. Optional larger Command Thrust gearcase delivers even more control for boats that sit lower in the water.

Exclusive Versatility.

Two exclusive features give the 115 Pro XS the versatility to outperform on a wide range of applications.

Available in two shaft lengths – 20″ and 25″ – this engine is an ideal option for a wide range of freshwater and saltwater boats.
    
The Command Thrust model, compatible with Mercury’s larger-diameter propellers, helps quickly lift heavy boats onto plane and hold them there at lower speeds.
