2018 Suzuki Marine 20 HP DF20AS EFI Outboard Motor

2018 Suzuki Marine 20 HP DF20AS EFI Outboard Motor

The 2018 Suzuki DF20AS EFI is not just another small outboard motor—it’s a breakthrough in compact engine design. Suzuki Marine engineers crafted this engine to be the most technologically advanced 20 horsepower four-stroke outboard in its class. With cutting-edge features like battery-less Electronic Fuel Injection (EFI), Lean Burn control, and next-generation engineering, the DF20AS stands as a powerful, fuel-efficient, and environmentally responsible solution for your boating needs.

Whether you’re navigating a small fishing boat, an inflatable craft, or a lightweight tender, the DF20AS brings reliability and innovation to every outing. If you’re in the market for a durable and portable engine that delivers unmatched performance, the DF20AS should be your top choice.

Advanced EFI System – No Battery Needed

One of the most revolutionary aspects of the DF20AS EFI is its battery-less electronic fuel injection system. Traditionally, EFI systems require a battery to deliver precise fuel amounts to the engine. However, Suzuki eliminated the need for a battery by engineering a system that draws energy from manual starts or from the engine’s own magneto.

This innovation simplifies the outboard’s design, reduces weight, and improves reliability in remote environments where battery maintenance can be a hassle. It also enhances cold-start performance, ensuring the motor kicks on smoothly regardless of weather conditions.

Lean Burn Control System for Unmatched Fuel Economy

Fuel economy is one of the most critical factors for today’s boaters. Suzuki’s Lean Burn control system adjusts the air-fuel mixture based on operating conditions, resulting in a more efficient burn during cruising speeds. This technology means lower fuel consumption, longer trips between refueling, and a lower environmental footprint.

Tests show that the DF20AS can deliver up to 15% better fuel efficiency compared to earlier models in similar power categories, making it an excellent option for eco-conscious boaters.

Lightweight and Compact Design

Weighing just 97 pounds (44 kg), the DF20AS is one of the lightest outboard motors in its class. Its compact design makes it easy to transport, mount, and store, especially for those using portable boats or switching between vessels.

Despite its light build, the DF20AS doesn’t sacrifice power or durability. The motor includes a high-performance gear case and strong internal components built to withstand harsh marine environments.

User-Friendly Operation

Ease of use is a core part of the DF20AS’s design philosophy. From its simple pull-start mechanism to smooth throttle response, this engine is beginner-friendly and low-maintenance.

Key user-friendly features include:

• Manual Start with Easy Pull: No need for an electric starter or battery.

• Forward-Mounted Shift Lever: Allows smooth and ergonomic gear changes.

• Oil-Change System: Easy-access oil fill port and drain plug.

• Shallow Water Drive: Allows operation in low-water conditions without damaging the propeller or lower unit.

These features make the DF20AS ideal for solo boaters, fishing trips, or recreational outings.

Superior Performance and Quiet Operation

Despite being a 20 horsepower engine, the DF20AS delivers smooth and quiet operation. Its 327cc three-cylinder engine provides ample torque for mid-sized boats while maintaining a low noise level.

The motor’s advanced engine mounts and anti-vibration design reduce operating noise and harshness, giving you a more pleasant ride. Whether you’re trolling for fish or cruising a lake, you’ll appreciate the silence and smoothness of this Suzuki outboard.

Built for Longevity and Reliability

Durability is key for any outboard engine. The DF20AS is built with Suzuki’s renowned corrosion-resistant materials, including a special anti-corrosion finish on the motor’s exterior and internal components.

The engine’s cooling system features a water separator to prevent moisture buildup, while a stainless steel water pump housing increases reliability. Routine maintenance is also simplified with accessible filters, spark plugs, and oil drain systems.

The DF20AS is perfect for:

• Aluminum fishing boats
