🔍 Model Background

The Mercury Verado 400 HP V10 outboard (2023–2024) represents the next generation of high-performance marine propulsion, built for offshore anglers, luxury center consoles, and performance craft. Introduced in late 2022 as a 2023 model, the 400 Verado marked Mercury’s first use of a naturally aspirated V10 5.7L powerhead, offering a powerful alternative to the older supercharged inline-6 models.

With its 350–400 HP range, the V10 Verado delivers exceptional acceleration and top-end power while maintaining smooth, quiet operation at cruising speeds. It features dual overhead cams (DOHC), electronic throttle and shift (DTS), integrated electro-hydraulic steering, and compatibility with Mercury’s Advanced MidSection (AMS) for reduced vibration and noise. Notably, it’s also compatible with Mercury’s Pro XS Sport Master gearcase and Joystick Piloting systems.

The Verado 400 V10 was designed to reduce weight and improve fuel economy while enhancing serviceability with features like a top-mounted oil filter and no-cowl service door. Built for heavy loads and harsh saltwater environments, it reflects Mercury's commitment to pushing innovation in the outboard category. As of 2024, the 400 V10 sits near the top of Mercury's Verado lineup and continues to gain popularity among serious boaters worldwide.
