Incredible power, combined with light weight, gives you mind-blowing performance.

Ideal for freshwater bass or multispecies - and saltwater flats or bay boats.

Standard Features
  • Phantom Black
  • 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.
  • 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.
  • 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.
  • Repower Financing.
    With Mercury Repower Financing, you can easily power up everything from fishing boats, to runabouts, to cruisers with flexible financing on the engine. You can also choose to finance rigging, gauges, controls and even labor. Mercury Repower Financing offers low rates and low monthly payments to fit a boater's budget.
