The Mercury Racing 250R delivers unrivaled performance for lightweight, single-engine sport, bass and bay boats. The 250R outboard has the muscle to lift a heavy tournament boat out of the hole plus the deep-breathing power and high-performance components required to reach outrageous speeds, with confidence. Run with the Mercury Racing 250R on the transom and run out front.
“Only Mercury Racing could deliver this level of V8 performance in the 250 class.”

Strong and rock-steady, the Mercury Racing tri-ram midsection features solid lower engine mounts and a high-durometer upper mount for enhanced stability and handling at high speeds, critical for confident control in the fastest, single-engine applications.
Mercury Racing has tuned the 250R outboard model to produce the perfect combination of low-end grunt and high-winding horsepower. A performance-tuned intake runner helps pack more air through the deep-breathing 32-valve dual overhead cam valve train to squeeze more power from the V8 4.6-liter engine. Mercury Transient Spark Technology optimizes torque output for stronger hole-shot performance.
The race-proven Sport Master surface-piercing gearcase is designed specifically for speeds greater than 85 mph and features low water pick ups and a crescent leading edge to maximize efficiency and velocity. Use a selection of Mercury Racing propellers to dial-in performance.
The dual muffler system of Advanced Sound Control offers the option of a deep sport tone with a stirring growl on start-up.

To squeeze more power from less fuel, naturally aspirated Mercury Racing V8 outboards feature Advanced Range Optimization (ARO), a closed loop fuel-control system that utilizes electronic sensors to precisely adjust the fuel mixture for the best-possible efficiency at all speeds. Mercury Racing 250R is engineered to be reliable and durable. A rugged midsection is designed to handle all the high-performance abuse the water can dish out. Superior protection against corrosion begins with the industry’s lowest-copper aluminum alloy and exclusive, comprehensive finish treatments. These high-performance outboards are tested, tested and tested again – in the lab and on the water – in a never-ending quest to exceed the highest expectations.

Enhance high-speed control and all-around comfort with optional Mercury electro-hydraulic power steering. Smooth and precise electronically actuated throttle and shifting matched to manual controls eases re-power installations and enables easier installation of a foot throttle.
The Mercury Racing 250R delivers a reliable, powerful performance punch on readily available 87-octane fuel.
Exclusive Idle Charge battery management helps prevent battery drain on boats loaded with power-hungry fishing electronics and audio systems. When Idle Charge detects low battery voltage it automatically increases idle rpm to boost alternator output until batteries are recharged. An 85 amp belt-driven alternator is designed to run cooler and maintain peak charging performance in the most-demanding conditions.
SmartCraft® Integrated Marine Technology with Engine Guardian® monitors vital engine sensors for early indications of problems and takes corrective action to reduce the risk of engine damage. Critical engine data can also be displayed on a SmartCraft System instrument or a compatible display screen.
