New 2026 Mercury Verado 400HP V10 Outboard Motor Engine 5.7L
Advanced Offshore V10 Power with Precision Control and Smooth Performance
The Mercury 400HP Verado V10 (400CXL) is a high-performance offshore outboard engine designed for large center consoles, sport fishing boats, and multi-engine offshore vessels. Built on Mercury’s advanced 5.7L V10 platform, it delivers exceptional horsepower, strong mid-range torque, and refined smoothness for demanding marine environments.
Equipped with Digital Throttle and Shift (DTS), integrated electric steering, and a 400CXL (25" Shaft) or 400CXXL (30" Shaft) provides precise handling, strong offshore stability, and efficient performance in rough water conditions. The counter-rotation (left-hand) configuration enhances balance and tracking in twin, triple, or quad engine setups.
Engine Performance & Technology
The Verado V10 is powered by a naturally aspirated 5.7-liter V10 engine, engineered for consistent offshore performance and smooth acceleration.
Key performance characteristics include:
- Strong mid-range torque for heavy offshore boats
- Smooth V10 firing sequence for reduced vibration
- Multi-Port Fuel Injection (MPI) for efficient combustion
- Optimized intake system for improved airflow and responsiveness
This combination delivers fast hole-shot performance, stable cruising, and confident power delivery under heavy load conditions.
Digital Throttle & Shift (DTS)
The Digital Throttle and Shift (DTS) system replaces mechanical linkages with advanced electronic controls for precise operation.
Benefits include:
- Instant and smooth throttle response
- Seamless gear shifting without mechanical lag
- Improved low-speed docking control
- Enhanced multi-engine synchronization
When integrated with Mercury SmartCraft systems, it enables advanced vessel features such as joystick docking and integrated helm control (system dependent).
Offshore Durability & Engineering
The Verado V10 is designed for demanding offshore use with advanced durability features:
- Heavy-duty V10 marine engine block for continuous operation
- Integrated electric steering system (no external hydraulics)
- Advanced vibration isolation mounts for smooth ride quality
- Corrosion-resistant marine-grade construction
- High-capacity cooling system for extended offshore runs
This ensures reliable performance even in harsh saltwater environments and heavy sea conditions.
400CXL (25" Shaft) or 400CXXL (30" Shaft)
The 400CXL (25" Shaft) or 400CXXL (30" Shaft) is designed for:
- Offshore boats with higher transoms
- Center consoles and deep-V hulls
- Twin, triple, or quad engine configurations
The counter-rotation (C – left-hand prop rotation) provides:
- Improved directional stability in multi-engine setups
- Reduced steering torque and easier handling
- Better straight-line tracking at high speeds
- Balanced thrust distribution across engines
