Mercury 350XXL 350HP – Verado Cold Fusion 30-Inch Shaft

Mercury 350XXL Verado 350HP L6 Cold Fusion

The Mercury 350XXL Verado is a specialized 350HP supercharged outboard designed for offshore high-transom offshore vessels in the North American maritime sector. Boasting the premium Cold Fusion White finish and a 2.6L Inline-6 architecture, this 702 lbs engine delivers unparalleled acceleration through advanced supercharged induction. This 30-inch ultra-long shaft model is configured for standard rotation, making it a premier choice for large multi-engine offshore platforms. Our reliable marine outboard engines provide the mechanical dependability and aesthetic excellence required for high-end coastal center consoles.

Maximum operational performance for the 350HP L6 occurs between 5800 and 6400 RPM, supported by Sequential Multi-Port EFI for optimized fuel delivery. The 1.75:1 gear ratio helps support the engine translates its supercharged boost into immediate heavy-load acceleration and steady hull planing. Proudly manufactured in the USA, this corrosion-resistant marine engine incorporates SmartCraft Digital Throttle & Shift (DTS) to helps support an incredibly smooth ride during long-range saltwater transits.

Technical Specifications of Mercury 350XXL Verado

- Supercharged 2.6L Inline-6 24-valve powerhead provides high-density torque for hole-shot and top-end performance.
- 30-inch ultra-long shaft helps support deep propeller immersion for specialized high-transom offshore deep-V hulls and walkarounds.
- Sequential Multi-Port EFI paired with a water-cooled supercharger provides instant boost and thermal management.

Supercharged Induction Advantage

The L6 Verado platform leverages a water-cooled supercharger to provide instantaneous boost. This eliminates the lag common in large naturally aspirated engines, providing the strong low-end grunt that offshore Boaters use when navigating strong tidal currents and unpredictable offshore winds in the American saltwater environment.

Ultra-Long 30-Inch Propulsion

The 30-inch ultra-long shaft is purposefully designed for offshore high-transom vessels requiring maximum propeller depth. This configuration prevents cavitation in large offshore swells and helps support consistent forward thrust on the heaviest deep-V hulls navigating unpredictable coastal waters, even under heavy supercharged loads.

Cold Fusion Aesthetics

The exclusive Cold Fusion White finish is more than just an aesthetic choice; it provides a premium appearance for modern offshore yachts. This high-durability coating is designed to withstand harsh maritime conditions while maintaining a clean, professional profile and providing legendary corrosion resistance.

Mercury Factory Warranty

Mercury Marine protects this 350HP L6 Verado outboard with a comprehensive 3-Year Limited Warranty for US owners. This factory-backed coverage helps support access to genuine replacement parts and certified technicians, reflecting a deep commitment to long-term maritime reliability and supercharged performance.

Maintenance & Longevity

Maintaining clean oil in the 8.0L wet sump lubrication system is vital for preserving engine tolerances under high boost. 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.
