The Mercury Verado 400hp V10 outboard represents a new era of high-horsepower marine performance, blending raw power with unprecedented refinement. It harnesses a 5.7-liter V10 powerhead – Mercury’s first-ever V10 – to deliver 400 horsepower with ease. Boaters will feel the punchy acceleration and strong midrange pull that the large displacement provides, ideal for swiftly getting on plane or confidently overtaking when needed. Yet what truly sets the 400 Verado apart is its remarkably smooth and quiet operation. Building on the advanced legacy of the Verado family, this engine features Mercury’s refined Advanced MidSection (AMS) mounting system, which virtually eliminates vibration by suspending the powerhead away from the transom. Coupled with extensive noise-reduction innovations – tuned intake, injector noise shields, and more – the V10 Verado runs whisper-quiet, up to 45% quieter at cruise than its closest competitor, so conversations on board remain easy even when you open up the throttle.
Mercury packed the 400 V10 Verado with cutting-edge features to elevate your boating experience. The Digital Throttle & Shift (DTS) controls deliver instantaneous, precise throttle response and buttery-smooth shifting, with zero hesitation. For multi-engine configurations, an optional integrated electric steering system further enhances control, reducing steering effort and drawing less power. The Verado 400 also introduces Mercury’s exclusive Advanced Sound Control, which lets you choose between a virtually silent idle or a throatier growl at startup and low speeds – tailoring the engine’s sound to your preference. Meanwhile, Adaptive Speed Control automatically adjusts the engine to maintain set RPM when conditions or loads change – climbing large swells or carving sharp turns is handled gracefully, without constant throttle adjustments.
Despite its high performance credentials, the 400hp V10 is designed with efficiency and ease of ownership in mind. It runs on 87-octane fuel and features a closed-loop fuel system along with Mercury’s Advanced Range Optimization (ARO) to maximize fuel economy on long runs. An easy-access oil check door on the top cowling takes the hassle out of routine maintenance – you can check or add oil without removing the entire cowling, and all service points are clearly marked for simplicity. Plus, with premium corrosion-resistant coatings and heavy-duty components, the V10 Verado is built to withstand the harshest marine environments, ensuring many years of reliable performance.
- Ideal use cases: Luxury offshore center-console boats, large RIBs, and cruising yachts (approximately 8–10 meters in length) that demand high power combined with ultra-smooth operation and low noise. Also well-suited for twin or triple installations on larger sport boats and yachts where precise handling and quiet performance are paramount.
- Recommended for: Owners and operators seeking top-tier performance and comfort – the Mercury Verado 400hp V10 is an outstanding choice for high-end marine applications, including sportfishing, fast cruising boats, and government/rescue vessels, where the blend of power, refinement, and advanced technology delivers an unparalleled boating experience.
