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.
Highlights
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.Key Features
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.Specifications
