Mercury 250 HP Verado Outboard Motor with Electro-Hydraulic Steering, Trim, Tilt, and Long Shaft

The Mercury Verado 250 L is a 4-stroke outboard marine engine designed for premium yachts, large luxury boats, and multi-engine professional applications requiring a long shaft, featuring 250 HP / 186 kW and a 4600 cc V8 (8-cylinder) engine. The Verado series encompasses Mercury's most advanced outboards in the premium segment. It has been specially developed for high-end yachts and large boats with its AMS (Advanced Mid Section) gearcase and electro-hydraulic steering system.

Verado 250 L Series Features and Technology Advantages

Electro-hydraulic steering requires no mechanical cables—providing exceptional maneuverability precision and comfort. The AMS gearcase optimizes power transmission, increasing fuel efficiency. Active Trim automatic trim management comes standard.

• V8 (8-Cylinder) Engine (4600 cc): Electro-hydraulic steering requires no mechanical cables—providing exceptional maneuverability precision and comfort.
• Long Shaft (508 mm (20")): The propeller operates at optimum depth at the correct transom height.
• Electro-Hydraulic Steering: No mechanical cables—precise maneuverability control and low steering effort.
• Electric Start: Instant engagement with a key or button—comfortable and quick starting.
• Electric Trim and Tilt (Power Trim & Tilt): Adjust trim angle with a button while cruising—optimizes fuel efficiency; tilt raises the engine completely.
• Floating External Fuel System: Connection for a large capacity external tank—range determined by user needs.

Long Shaft — Which Boat Type Is It Suitable For?

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

Maintenance and Longevity

4-stroke Mercury engines operate trouble-free for many years with regular oil changes and end-of-season maintenance protocols. The impeller of the water-cooled system should be checked every 100 hours or every two seasons. In saltwater use, freshwater flushing is mandatory after each use.

Frequently Asked Questions

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

Verado offers an AMS (Advanced Mid Section) gearcase and electro-hydraulic steering system. Its design, which requires no mechanical cables, provides more precise maneuverability and lower maintenance. DTS digital throttle makes multi-engine synchronization easier.

How does the electro-hydraulic steering system work?

The electro-hydraulic system transmits 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, simultaneous turning 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—continuously optimizing fuel consumption and cruising comfort.

Which boat and brand models are compatible with the Verado 250 L?

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