New Suzuki 350HP DF350A Extra Long Shaft Outboard Engine: Power, Precision, and Performance

When it comes to marine engines, Suzuki has consistently set the benchmark for innovation, reliability, and high performance. The new Suzuki 350HP DF350A Extra Long Shaft Outboard Engine is the latest testament to this legacy, offering boat owners unparalleled power and advanced technology in a compact, durable design. Whether you’re a recreational boater, a professional angler, or someone who demands the best for your marine vessel, the DF350A promises an experience like no other.

Unmatched Power with a V6 Engine

At the heart of the DF350A lies a 3.6-liter V6 engine, delivering an impressive 350 horsepower. This high-output engine ensures rapid acceleration, smooth cruising, and excellent towing capacity for larger vessels. The extra-long shaft variant makes it ideal for deep V-hull boats and offshore applications where optimal performance and precise handling are critical.

Key Engine Highlights:

• Displacement: 3,555cc

• Horsepower: 350 HP

• Configuration: V6, DOHC, 24-valve

• Fuel Delivery: Suzuki’s Multi-Stage Induction System

• Maximum RPM: 6,300

This engine is engineered to maximize fuel efficiency while delivering extreme torque across a wide RPM range, making it perfect for both high-speed runs and steady, long-range cruising.

Extra Long Shaft: Designed for Deep Hulls

The extra-long shaft (XLS) configuration is designed specifically for boats with deep V-hulls or modified transoms. By providing extra reach, the engine ensures optimal propeller engagement, improving thrust, stability, and overall boat handling. This is particularly beneficial for larger fishing boats, offshore cruisers, and pontoon boats that operate in challenging marine conditions.

Benefits of the Extra Long Shaft:

• Superior hull clearance for deep V or modified boats

• Reduced cavitation and propeller ventilation

• Enhanced stability at high speeds and in rough water

• Greater versatility for various boat sizes and types

Cutting-Edge Features and Technology

The DF350A isn’t just about raw power—it’s also packed with innovative features to ensure superior performance, efficiency, and longevity.

1. Lean Burn Control System

Suzuki’s Lean Burn Technology continuously monitors engine operating conditions, optimizing the fuel-to-air ratio for maximum efficiency. Boaters enjoy better fuel economy, lower emissions, and longer cruising ranges.

2. Suzuki Selective Rotation

Unlike many outboard engines, the DF350A offers Selectable Rotation, allowing the engine to rotate either clockwise or counterclockwise. This adds versatility for dual-engine setups and improves maneuverability in tight docking situations.

3. Variable Valve Timing (VVT)

The VVT system enhances low-end torque while maintaining high-speed performance. This results in smoother acceleration, improved fuel efficiency, and more responsive handling.

4. Advanced Cooling System

The DF350A incorporates a high-capacity water-cooling system with multiple jets to prevent overheating, even during long hours on the water. The system ensures optimal engine temperature and reduces wear on critical components.

5. Electronic Fuel Injection

The engine uses Suzuki’s programmed fuel injection (PGM-FI) system for precise fuel delivery. This guarantees smooth starting in any condition, excellent throttle response, and minimal emissions.

Reliability and Durability

Suzuki engines are known for their exceptional durability, and the DF350A XLS is no exception. The engine features corrosion-resistant materials, reinforced mounting points, and robust engineering to withstand the harsh marine environment. With proper maintenance, the DF350A can deliver years of dependable service, making it a smart investment for serious boaters.

Noise and Vibration Reduction

Thanks to the Offset Driveshaft design and strategically engineered engine mounts, the DF350A XLS minimizes vibrations and reduces operational noise. This ensures a quieter, more comfortable ride—a feature especially appreciated during long trips or when trolling for fish.

Ideal Applications

The Suzuki DF350A Extra Long Shaft is perfect for a wide range of marine vessels, including:

• Offshore sportfishing boats

• Deep V-hull cruisers

• Large pontoon boats

• Commercial workboats

• Dual-engine setups for enhanced performance

Its combination of power, efficiency, and versatility makes it an excellent choice for both recreational and professional boating.

Maintenance and Support

Suzuki offers comprehensive after-sales support, including authorized service centers, genuine parts, and extended warranty options. Routine maintenance is straightforward, ensuring that your DF350A remains in peak condition for years to come.

Recommended Maintenance:

• Oil and filter changes every 100 hours or annually

• Spark plug inspection every 100 hours

• Cooling system flush after every 50 hours in saltwater

• Regular inspection of propeller, mounting, and fuel lines
