2026 Mercury Racing 250R

PERFORMANCE PERFECTED
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.

Tri-Ram Midsection
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.

Long-Runner Intake
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.

SPORT MASTER GEARCASE
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.

Feel the Power.
The dual muffler system of Advanced Sound Control offers the option of a deep sport tone with a stirring growl on start-up.

GO FARTHER, FASTER
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.

Power Steering Option
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.

87 Octane
The Mercury Racing 250R delivers a reliable, powerful performance punch on readily available 87-octane fuel.

Idle Charge
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 Technology
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.
