250R
V8 FOURSTROKE
Never Look Back
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.
Under the Cowl
4.6L V8
The 250R is part of the Mercury Racing V8 FourStroke outboard lineup, designed to be high-winding, rugged and reliable. It's loaded with advanced design elements and Mercury Racing technology to go quicker, faster and farther than previously imagined.
Long Runner Intake
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.
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.
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.
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. A 85 amp belt-driven alternator is designed to run cooler and maintain peak charging performance in the most-demanding conditions.
Go Farther Faster
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.
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.
