Mercury 400CL 400HP – Verado V10 20″ Shaft Counter Rotation DTS in Black

Mercury 400CL 400HP Verado V10 DTS

The Mercury 400CL Verado is a monumental 400HP FourStroke outboard featuring the industry-first naturally aspirated V10 architecture for the US offshore boating market. Built upon a 5.7L Dual Overhead Cam (DOHC) powerhead and weighing 695 lbs, this engine redefines high-performance through sheer displacement and digital precision. This 20-inch shaft model is configured for counter-rotation, making it the ideal port-side companion for dual-engine high-performance center consoles. Our dependable outboard propulsion systems is designed to support the vibration-free performance and electrical capacity required for premium coastal navigation. Operational peak performance for the Mercury 400HP V10 is aggressively maintained within the 5800 to 6400 RPM range, supported by a class-leading 150 Amp alternator. The 2.08:1 gear ratio translates the 5.7L torque curve into hole-shot acceleration and top-end speed on high-performance hulls. Manufactured in the USA, this corrosion-resistant marine engine incorporates SmartCraft Digital Throttle & Shift (DTS) and an integrated High-Output Electric/Hydraulic power steering system to helps support a silky-smooth, cable-free experience across turbulent offshore swells.

5.7L V10 Naturally Aspirated Power

The Mercury 400CL 5.7L V10 platform leverages a naturally aspirated DOHC design to provide the smooth, reliable torque that offshore Boaters use. This “displacement over forced induction” philosophy translates to durability, instantaneous low-end grunt for hauling heavy fuel loads, and incredibly smooth power delivery during high-speed offshore runs in the American saltwater environment.

Integrated High-Output Power Steering

Mercury’s integrated electric/hydraulic power steering system removes the need for external steering rams and hoses. This digital drive-by-wire steering provides captains with, precision control, which is vital when precisely docking large multi-engine center consoles in crowded American marinas or navigating high-speed coastal transits.

150A high-pressure Alternator

Equipped with a 150 Amp alternator, the V10 Verado provides unprecedented charging power. This robust output is essential for modern offshore boats equipped with multiple high-definition displays, radar, and complex entertainment systems, ensuring your battery bank remains fully charged even during long periods of idling in the open ocean.

Mercury 3-Year Protection

Every Mercury 400HP Verado V10 outboard is backed by a comprehensive 3-Year Limited Warranty for American owners. This factory-level protection helps support long-term peace of mind and grants access to genuine parts through a vast nationwide marine dealer network.

High-Performance Offshore Match

This Mercury 400CL 20-inch counter-rotation V10 outboard is a practical port-side power solution for large offshore center consoles and high-speed deep-V hulls. It provides the sustained high-end thrust needed for navigating difficult coastal tidal flows while offering digital maneuverability and whisper-quiet operation.

Maintenance & Longevity

Maintaining clean oil in the 8.0L integrated wet sump system is vital for preserving the V10’s tight engine tolerances. Always flush the cooling system with fresh water after every saltwater outing.Pro Tip from the Shop:Utilize the exclusive Top Cowl Service Door for daily oil checks and verify the SmartCraft NMEA Gateway health to helps support your high-output alternator and steering systems are communicating perfectly with your digital helm before every high-speed run.
