Mercury 300XXL 300HP – Verado Cold Fusion 30-Inch Shaft

Mercury 300XXL Verado 300HP V8 Cold Fusion

The Mercury 300XXL Verado is an 300HP FourStroke V8 outboard featuring the premium Cold Fusion White finish and Advanced MidSection (AMS) for a practical offshore experience in the United States. Built on a 4.6L 32-valve DOHC architecture and weighing 612 lbs, this engine redefines refinement through integrated electro-hydraulic power steering and vibration isolation. This 30-inch ultra-long shaft model is configured for maximum propeller immersion on offshore high-transom multi-engine offshore vessels. Our dependable outboard propulsion systems is designed to support the digital precision and silent operation required for premium coastal navigation.

Operational peak performance for the Mercury 300HP Verado is aggressively maintained between 5200 and 6000 RPM, supported by an high-pressure 115 Amp alternator. The 1.75:1 gear ratio, paired with the Advanced MidSection, translates the V8 torque into exceptionally smooth acceleration and high top-end speeds. Manufactured in the USA, this corrosion-resistant marine engine incorporates SmartCraft DTS technology to helps support a silky-smooth, cable-free shifting experience across turbulent saltwater swells.

Technical Specifications of Mercury 300XXL Verado

• The 4.6L V8 32-valve DOHC architecture delivers unparalleled displacement and strong low-end torque for heavy offshore loads.
• Advanced MidSection (AMS) provides a cradle-mount system that virtually eliminates engine vibration and noise in the vessel’s cockpit.
• Standard right-hand rotation optimized for primary single-engine or starboard-side multi-engine installations.
• Integrated Electro-hydraulic power steering offers, automotive-like handling even in rough coastal conditions.
• A 115 Amp alternator delivers 1449 Watts of charging power, the highest in its class for marine marine electronics.
• Digital Throttle & Shift (DTS) provides instantaneous helm responsiveness without the friction of mechanical cables.

Advanced MidSection (AMS) Technology

The Verado series is defined by the Advanced MidSection, which isolates the powerhead from the transom using specialized mounts. This engineering provides a significant reduction in vibration, ensuring that offshore cruisers enjoy a whisper-quiet ride during long transits through the American saltwater environment, even at high cruising speeds.

Cold Fusion White Aesthetics

The exclusive Cold Fusion White finish is a high-durability coating designed to withstand the harsh UV rays and salt spray of the US coastal environment. This aesthetic choice complements modern offshore yacht designs while providing the same legendary corrosion resistance as traditional Phantom Black models.

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 center consoles navigating unpredictable coastal waters.

115A High-Output Charging

Equipped with a 115 Amp alternator, the Verado provides class-leading charging power. This robust output is essential for modern offshore boats equipped with multiple high-definition displays, radar, and gyrostabilizers, ensuring your battery bank remains healthy during extended offshore transits.

Mercury 3-Year Protection

Every Mercury 300HP 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.

offshore High-Transom Match

This 30-inch Verado outboard is a practical power solution for ultra-high transom offshore boats and large walkarounds. It provides the sustained high-end thrust needed for navigating difficult coastal tidal flows while offering digital maneuverability and silent operation.

Maintenance & Longevity

Maintaining clean oil in the 7.0L integrated wet sump system is vital for preserving tight engine tolerances over time. 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.
