Description
Why the Mercury Racing 400R Sets the Gold Standard
-
Supercharged Turn-Key Power: Unlike naturally aspirated engines that rely purely on displacement, the 400R utilizes a water-cooled supercharger system. This packs cool, dense air into the cylinders to generate immediate, linear torque across the entire powerband—giving you a neck-snapping hole shot and relentless mid-range acceleration.
-
Low Hours, High Longevity: At just 500 hours, these motors are in the prime of their operational life. They have been lightly enjoyed and strictly maintained, offering their next owner a massive discount compared to the cost of a brand-new pair from a dealer.
-
Sport Master / 5.44″ Heavy-Duty Gearcases: Engineered to handle the massive stress of high-speed surfacing conditions, the robust lower units provide maximized hydrodynamic efficiency, reducing drag while transferring every ounce of horsepower cleanly to the water.
-
Stunning Clean White Aesthetics: Finished in Mercury Racing’s ultra-premium cold fusion white with sharp graphics, these outboards instantly modernize the look of any boat transom, giving it a commanding, aggressive slip presence.
-
Advanced SmartCraft Integration: Fully compatible with Mercury’s high-tech digital ecosystem, allowing seamless pairing with Digital Throttle & Shift (DTS) controls, VesselView multi-touch screens, and automated active trim systems for an effortless driving experience.
Condition & Maintenance Notes
These engines have been pampered by a meticulous boat owner from day one:
-
Fully documented routine maintenance, including regular impeller, spark plug, and gear lube changes.
-
Thoroughly flushed with fresh water after every outing to prevent any salt or mineral buildup within the cooling passages.
-
No docking scars, deep gouges, or sun fading—the fiberglass cowlings and factory paint retain their deep, brilliant showroom gloss.
