Suzuki engineers have packed the new in-line three-cylinder DF30A with some of Suzuki's finest technologies giving them class-leading advantages that put them ahead of the rest. Engineering lightweight outboards have long been a Suzuki hallmark.
New Generation Fuel Injection System (Battery-Less Fuel Injection)
Fuel is supplied with Suzuki's Lean Burn Control system and a Battery-Less Fuel Injection system that gives these outboards remarkable improvements fuel efficiency while maintaining excellent power and performance.
Suzuki Lean Burn Control Technology
Suzuki's Lean Burn Control System is an intelligent system that monitors engine performance and operating conditions to predict fuel needs and deliver a leaner fuel mixture to the engine. First introduced on the DF90A/80A/70A, and later on the DF60A, this system provides remarkable improvements in fuel economy from low speed operation up into the cruising range, which is where the engine is used a majority of the time. In-house testing shows that at medium speeds, the DF50A achieves a 23% improvement in fuel consumption than its predecessor.
First In Class with Roller Rocker Arms
Both are first in class to feature friction reducing roller rocker arms and each utilizes offset crankshafts resulting in smoother operation and greater mechanical efficiency.
Engine Monitoring Led Indicators
An LED monitoring system provides engine operating status at a glance.
Lower Emissions, Efficient Operation
Suzuki's highly efficient four-stroke technologies produce lower emissions that allow outboards like the DF25A/30A to conform to some of the world's strictest emissions standards*1 including the EURO 1 emissions Standards (EU Directive 2003/44EC)*2, and receive a three-star rating from the California Air Resources Board (CARB).
*1: Emission standards compliancy is region specific.
*2: The EU emissions standards (exhaust gases and noise levels) set by the European Parliament and Council.
Lightest outboards in the 18.4kW (25PS)/22.1kW (30PS) four-stroke outboard class*3.
Lean Burn Control and Battery-Less Fuel Injection deliver class-leading fuel-efficiency.
First in class with Roller Rocker Arms that provide smoother action and reduce friction.
Offset Crankshaft offers smoother piston movement for greater operating efficiency.
Direct Air Intake and Ventilation supplies engine with a cooler airflow for greater efficiency.
Engine Monitoring LED Indicators keep you informed of operating conditions.

New Generation Fuel Injection System (Battery-Less Fuel Injection)
A remarkably compact and lightweight fuel injection system is designed to fit into these outboards without adding unneeded bulk or weight. What's more, it operates without a battery and still delivers quicker starts, smoother operation, and more acceleration in all conditions.
Suzuki Lean Burn Control System
Suzuki's advanced four-stroke technologies deliver clean and efficient outboard operation that conforms to EURO 1 Emissions Standards (EU Directive 2003/44/EC)—the EU emissions standards (exhaust gases and noise levels) set by the European Parliament and the Council, and have received three-star ratings from the California Air Resources Board (CARB).
Direct Intake And Engine Cover Ventilation
A new engine cover design provides the direct intake system with a smoother, cooler flow of air boosting engine operating efficiency. This, together with a newly designed air cleaner allows higher power output from a small displacement.
The rotating flywheel helps reduce temperatures inside the engine cover by venting warm air to the outside from the recoil cover, inner air intake, and engine upper cover.
First In Class With Roller Rocker Arms
These are the first outboards in their respective classes to utilize a roller with internal bearings on the cam slipper surface for both the intake and exhaust valves. The roller changes contact between the camshaft and rocker arm from a conventional sliding action to a rolling action reducing friction in rocker arm operation.
Offset Crankshaft
Positioning the crankshaft slightly off center of the cylinder reduces lateral pressure against the cylinder wall as the piston moves up and down in the cylinder. The result is smoother piston movement, which improves operating efficiency.
Easy Start Recoil
Fuel injection delivers easier starts, but Suzuki goes a step further incorporating a very light recoil starter into these outboards. Requiring less pull strength, the Easy Start Recoil Starter makes starting the outboard quick and easy.
Engine Monitoring LED Indicators
The LED monitoring system utilizes three LEDs to keep you informed of current operating conditions. Located in an easily visible position, the LEDs provide easy to understand monitoring at a glance so you can enjoy a pleasurable boating experience.
Engine Flush Port
To help protect the engine from damage caused by salt, sand, and dirt that can build up in the engine's cooling system, the outboards are equipped with an easy to access freshwater flush port to make cooling system flushing as easy and convenient as possible.
Suzuki Anti-Corrosion System
Suzuki protects the outboard's exterior from harmful corrosion with its own specially formulated anti-corrosion finish. Applying the finish directly to the outboard's aluminum surface, allows maximum bonding of the finish to the surface to increase durability and help protect parts that are constantly exposed to saltwater.
