The Mercury 400XXXL White Verado V10 is a high-performance four-stroke outboard motor, featuring the industry’s first naturally aspirated V10 powerhead, finished in a Cold Fusion White color for a sleek, modern aesthetic. Designed for large offshore boats, center consoles, multi-hulls, and heavy vessels, this 400 HP motor with a 35-inch ultra-long shaft delivers exceptional power and efficiency with a 5.7L (349 cubic inch) displacement and a maximum RPM range of 5800-6400. It includes Digital Throttle & Shift (DTS) for smooth, instantaneous control, electric start, and power trim/tilt. The Advanced MidSection (AMS) and under-cowl noise management reduce vibration and noise, making it 45% quieter than competitors at cruising speed. A 150-amp alternator, the highest in its class, provides four times the output of competitors at cruise, supporting heavy electronics loads. The hydrodynamic gearcase with a large-diameter Revolution X™ propeller enhances high-speed efficiency and low-speed handling. Advanced Sound Control allows toggling between a quiet exhaust or a sportier tone. Built for durability, it uses advanced alloys, corrosion-resistant coatings, and a freshwater flush system for saltwater reliability. Calibrated for 87-octane fuel with Advanced Range Optimization (ARO), it offers superior fuel economy for long-distance runs.

4 reviews for Mercury 400hp White Verado V10 35″ Shaft | 400XXXL
best engine i’ve ever owned by far reliable, smooth, and plenty of torque the white finish looks great and the power delivery is flawless got it at a solid price too
runs like a dream, the 35” shaft gives me the depth i need for serious fishing trips super quiet and strong motor highly recommend this model
this white verado 400hp v10 is pure power smooth as silk and crazy responsive handling is top-notch the 35” shaft fits perfectly on my boat very happy with it
impressive motor with strong acceleration quiet for a 400hp but fuel consumption is on the higher side took some time to get used to the weight but overall a beast
