2018 Suzuki Marine 25 HP DF25AS EFI Outboard Motor

2018 Suzuki Marine 25 HP DF25AS EFI Outboard Motor – A Revolution in Portable Boating Power

When performance, portability, and innovation matter, the 2018 Suzuki DF25AS EFI Outboard Motor sets a new industry benchmark. As one of the most advanced 25 HP portable outboard engines on the market, this model redefines efficiency and power in a lightweight, easy-to-use package.

Suzuki Marine has long been synonymous with cutting-edge technology, and the DF25AS EFI is no exception. With its battery-less electronic fuel injection (EFI) system and Lean Burn Control, it’s engineered for boaters who demand superior fuel economy, fast starting, and clean performance. Whether you’re fishing in shallow waters or cruising across a lake, this outboard ensures a seamless and environmentally conscious ride.

Advanced Fuel Efficiency with Lean Burn Control

One of the defining features of the DF25AS is Suzuki’s Lean Burn Control system. This intelligent technology adjusts the fuel mixture in real time, optimizing fuel consumption based on operating conditions. The result? Up to 14% better fuel economy compared to previous models in the same horsepower range.

This lean-burn technology is not just about saving on gas – it also means fewer emissions, aligning with today’s growing demand for greener, cleaner marine engines.

Battery-Less Electronic Fuel Injection – Game-Changing Simplicity

The battery-less EFI system sets the DF25AS apart from conventional portable outboards. While many motors in this class require a separate battery to manage fuel injection, Suzuki’s design eliminates that need. The EFI system draws power directly from the pull-start, making it easier to use, lighter to carry, and more reliable in remote settings where battery issues can become problematic.

This innovation ensures instant, hassle-free starts, even in cold weather or after long periods of non-use.

Impressive Performance in a Lightweight Design

Despite its compact form, the 2018 Suzuki DF25AS delivers robust performance. With 25 horsepower at 5000-6000 RPM and a 489cc three-cylinder engine, it offers excellent acceleration, mid-range torque, and cruising capabilities. It’s equally at home powering small fishing boats, dinghies, or lightweight skiffs.

At just 136.6 lbs (manual start) and 143 lbs (electric start), this motor is one of the lightest in its class, offering incredible portability without compromising on power.

Smooth Operation and User-Friendly Features

Boaters will appreciate the DF25AS’s thoughtful design elements. It includes:

• Digital CDI ignition for consistent, smooth firing

• Freshwater flushing system for extended engine life

• Over-rev limiter and low oil pressure warning for built-in protection

• Shallow water drive for navigating tight or low-depth areas

The five tilt pin positions also provide fine-tuned control over trim and tilt, ensuring optimal performance in various water conditions.

Durability and Long-Term Reliability

Suzuki’s anti-corrosion system ensures that the DF25AS is built to withstand harsh marine environments. The motor’s robust aluminum alloy components are treated with a specially formulated anti-corrosion finish, providing lasting protection against salt, sun, and wear.

This commitment to durability is backed by a three-year limited manufacturer warranty, giving you peace of mind with every outing.
