Mercury 400XL 400HP Verado V10 25″ Shaft Outboard Motor

Mercury 400HP 400XL Verado V10 Extra Long Power

Featuring a 5.7L V10 engine family, the Mercury 400HP 400XL Verado serves as a high-torque solution for US offshore boaters requiring a prop-rated propulsion unit with superior thermal stability. This 400HP four-stroke technology utilizes a naturally aspirated 10-cylinder architecture and Advanced MidSection (AMS) to maximize mechanical efficiency and torque density for heavy offshore vessels and premium center consoles. The 25-inch extra-long shaft design provides an optimized center of gravity, while the Digital Throttle and Shift (DTS) ensures immediate, reliable ignition across diverse inland and coastal environments.

Operational longevity of the 400XL Verado model is secured through a specialized pressurized lubrication system featuring a high-capacity gearcase and SmartCraft digital monitoring to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a sophisticated multi-port EFI system paired with a 150A high-output alternator, while the Mercury XK360 alloy science utilizes a multi-layer finish to mitigate oxidation in high-salinity waters. With a 3-year/300-hour service interval and whisper-quiet operation, this fuel-efficient outboard provides superior ownership value for boaters seeking professional-grade displacement and unmatched refinement.
