DF30A / DF25AT / DF30AT / DF25A

DF30A

Suzuki engineers have packed the new in-line three-cylinder DF25A/DF30A with some of Suzuki's finest technologies giving them class-leading advantages that put them ahead of the rest. Engineering lightweight outboards has long been a Suzuki hallmark.

DF30A / DF25A

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).

RCD EMISSIONS STANDARDS / ULTRA LOW EMISSION
*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.

Diagram of Direct Intake And Engine Cover Ventilation

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.

First In Class With Roller Rocker Arms

Offset Crankshaft

A powerful 19-amp alternator is designed to generate a minimum of 11.5 amps of power even with the engine running at a low 1,000rpm. Under normal circumstances that's enough power to keep an assortment of marine electronics operating in most situations.

Offset Crankshaft

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.
