Mercury 300 HP Verado Outboard Motor with Electro-Hydraulic Steering, Power Trim & Tilt, and Long Shaft

The Mercury Verado 300 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 300 HP / 221 kW and a 4600 cc V8 (8 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) gearcase and electro-hydraulic steering system.

Verado 300 L Series Features and Technology Advantages

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

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

Long Shaft — What Type of Boat is it Suitable For?

The long shaft (508 mm (20")) is suitable for the vast majority of inflatable, aluminum, 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 yacht and luxury large boat: highest comfort with electro-hydraulic steering and AMS gearcase.
• Multi-engine configuration: consistent power distribution and DTS synchronization.
• Long-distance offshore cruising: Active Trim and automatic fuel management.

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 key difference between the Verado series and standard FourStroke?

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

How does the electro-hydraulic steering system work?

The electro-hydraulic system transmits steering movement electronically 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 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 Verado 300 L?

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 transom height of 508 mm (20") and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
