Mercury 350CXL 350HP – Verado Four Stroke Counter Rotation 25-Inch

Mercury 350CXL Verado 350HP L6 Supercharged

The Mercury 350CXL Verado is a high-performance 350HP outboard featuring the legendary supercharged Inline-6 architecture for the US offshore marine market. Utilizing a 2.6L 24-valve platform with charge air cooling and weighing 668 lbs, this engine is engineered for strong acceleration and high-speed transit. This 25-inch extra-long shaft model is configured for counter-rotation, making it the appropriate port-side companion for dual-engine high-performance hulls. Our dependable outboard propulsion systems is designed to support the mechanical intensity and digital precision required for rigorous coastal operations.

Operational peak performance for the L6 Verado occurs between 5800 and 6400 RPM, utilizing a water-cooled supercharger to maintain consistent intake density. The 1.75:1 gear ratio translates the supercharged torque into hole-shot acceleration. Manufactured in the USA, this corrosion-resistant marine engine incorporates SmartCraft Digital Throttle & Shift (DTS) and electro-hydraulic power steering to helps support a hyper-responsive, cable-free experience across turbulent offshore swells.

Supercharged L6 Engineering

The 2.6L L6 Verado is defined by its supercharged induction system, which provides instant boost regardless of atmospheric conditions. This technology helps support that American offshore anglers experience zero lag during acceleration, delivering the high-revving performance required to maintain speed in heavy following seas and choppy coastal inlets.

Charge Air Cooling Precision

To maintain peak thermal efficiency, the supercharger is paired with an advanced charge air cooler. This system reduces the temperature of compressed air before it enters the combustion chamber, preventing knock and ensuring that the 350HP output remains consistent during long-range offshore runs in high-temperature maritime environments.

25-Inch Offshore Propulsion

The 25-inch extra-long shaft helps support the propeller operates at the optimal depth for maximum hydrodynamic grip on large offshore transoms. This design prevents cavitation and maintains consistent forward thrust on mid-sized deep-V hulls navigating through unpredictable coastal chop and strong tidal flows.

Mercury 3-Year Protection

Every Mercury 350HP L6 Verado 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 Center Console Match

This counter-rotation supercharged outboard is a practical port-side power solution for high-performance offshore center consoles and deep-V walkarounds. It provides the sustained high-end thrust needed for competitive angling and rapid transit while offering digital maneuverability.

Maintenance & Longevity

Maintaining the 8.0L integrated wet sump lubrication system is vital for preserving the engine’s tight mechanical tolerances under supercharged loads. Always flush the cooling system with fresh water after every saltwater outing.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
