Why Buy the Mercury 115 HP Pro XS from Outboard Motors Shop
The 115 Pro XS isn’t just an ordinary 115-horsepower motor; Mercury tuned it specifically for speed and aggressive acceleration. Built on a 2.1-liter, eight-valve, single overhead cam design, it boasts the highest displacement in its category while remaining surprisingly lightweight.

Real-World Boat Engine Performance and Fuel Economy
Out on the water, the difference between a standard four-stroke and a Pro XS is night and day. Thanks to its lightweight engineering—weighing in at just around 359 pounds—this motor delivers an unmatched power-to-weight ratio. You get the punchy torque drivers usually associate with traditional two-strokes, combined with the whisper-quiet, smoke-free efficiency of modern four-stroke technology.
Whether you run a bass boat, bay boat, or deep-v aluminum vessel, the fuel economy on this engine lets you stay out longer without constantly eyeing the fuel gauge. For independent marine safety guidelines and performance tips, consult the U.S. Coast Guard Boating Safety Division.

Getting the most out of your 115 Pro XS comes down to matching it with the right propeller. A standard aluminum prop might get the job done for cruising, but switching to a stainless steel prop (like the Mercury Fury or Enertia series) unleashes its true top-end speed and grip during sharp turns.
