Mercury 350 HP Verado V10 Electro-Hydraulic Power Steering with Trim and Tilt Long Shaft Outboard Engine

The Mercury Verado 350 L AMS DTS V10 is a 4-stroke outboard marine engine designed for premium yachts, large luxury boats, and multi-engine professional applications requiring a long shaft, featuring 350 HP / 257 kW and a 5700 cc V10 (10 Cylinder) engine. The Verado series encompasses Mercury's most advanced outboard engines in the premium segment. It has been specifically developed for high-end yachts and large boats with its AMS (Advanced Mid Section) gearbox and electro-hydraulic steering system.

Verado 350 L AMS DTS V10 Series Features and Technology Advantages

Electro-hydraulic steering eliminates the need for mechanical cables, providing exceptional maneuverability precision and comfort. The AMS gearbox optimizes power transfer, increasing fuel efficiency. Active Trim automatic trim management comes standard.

• V10 (10 Cylinder) Engine (5700 cc): Electro-hydraulic steering eliminates the need for mechanical cables, providing exceptional maneuverability precision and comfort.
• Long Shaft (508 mm (20")): The propeller operates at optimal depth with the correct transom height.
• Electro-Hydraulic Steering: No mechanical cables — precise maneuver control and low steering effort.
• Electric Start: Instant engagement with a key or button — comfortable and quick starting.
• Electric Trim & Tilt (Power Trim & Tilt): Adjust trim angle with a button during cruising — optimizes fuel efficiency; tilt allows raising the engine completely out of the water.
• External Floating Fuel System: Connection to a large-capacity external tank — range determined by user need.

Long Shaft — Which Boat Type Is It Suitable For?

The long shaft (508 mm (20")) is suitable for the vast majority of inflatable boats, aluminum boats, and fiberglass boat models. For boats with a transom height of 381 mm, a short shaft model should be preferred.

Technical Specifications

Who is this engine for?

• Premium yachts and luxury large boats: highest comfort with electro-hydraulic steering and AMS gearbox.
• Multi-engine configuration: consistent power delivery and DTS synchronization.
• Long-distance offshore cruising: Active Trim and automatic fuel management.
• Rental luxury yachts and charter: high reliability and low maintenance costs.

Maintenance and Longevity

4-stroke Mercury engines operate smoothly for many years with regular oil changes and an end-of-season maintenance protocol. Impeller inspection for the water-cooled system should be done every 100 hours or every two seasons. Fresh water flushing is mandatory after each use in saltwater.

Frequently Asked Questions

What is the main difference between the Verado series and standard FourStroke?

Verado offers an AMS (Advanced Mid Section) gearbox and an electro-hydraulic steering system. Its design, which does not require mechanical cables, provides more precise maneuvering and lower maintenance. DTS digital throttle and shift facilitates the synchronization of multiple engines.

How does the electro-hydraulic steering system work?

The electro-hydraulic system transmits the steering movement via an electronic signal to a hydraulic actuator. Since there is no mechanical cable friction, it provides much lower steering effort and higher precision. In multi-engine applications, the simultaneous rotation of the engines is automatically coordinated.

What does the Active Trim system do?

Active Trim automatically optimizes the trim angle using GPS speed and acceleration data. It eliminates the need for manual trim adjustment during speed changes — fuel consumption and cruising comfort are continuously optimized.

Which boat and boat brands are compatible with the Verado 350 L AMS DTS V10?

Mercury outboard motors are compatible with many fiberglass, aluminum, and inflatable boat models due to their universal transom clamp or transom mounting system. The only criteria are your boat's 508 mm (20") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
