Overview

State-of-the-Art designs make the new DF25A the most technically advanced portable outboard on the market today. This is the world’s first 25 hp outboard motor designed with Lean Burn and Battery-Less Electronic Fuel Injection. The Suzuki EFI system operates Battery-Less, which is an industry first in this horse-power class. The DF25A is a smooth running “Next Generation” four stroke which delivers quick starts, great accelleration, awesome performance and superior fuel economy. Go Lean, Clean and Green, Go Suzuki!

Own The Best – Suzuki DF25A Outboard Wins The Innovation Award at 2014 IBEX Show
Suzuki Motor Corporation’s NEW DF25A four-stroke outboard motor have received the National Marine Manufacturers Association’s (NMMA) 2014 IBEX Innovation Award for outboard motors at the International Boat Builder’s Exhibition & Conference (IBEX).

IBEX Innovation Awards are the best awards in the marine technology, which are given to those new products in the marine industry that demonstrate distinctive technological advancements and deliver practical, cost-effective consumer benefits.

This is the eighth Innovation Award won by Suzuki outboards (of which seven were won by four-stroke outboards), which accredits their high technologies.

Lightest In Class*4

Featuring some of Suzuki’s best technologies, the DF25A/30A are the lightest outboards available in the 18.4kW (25PS)/22.1kW (30PS) four-stroke outboard class.*4

*4:According to in-house investigations as of February 2014

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 DF25A Suzuki Lean Burn Control System

This intelligent fuel management system predicts fuel needs by monitoring engine performance and operating conditions to deliver a leaner fuel mixture to the engine. The result is remarkable improvements in fuel economy.

Suzuki DF25A 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.

Suzuki DF25A External Air Flow

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.

Suzuki DF25A 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.

Suzuki DF25A 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.

Suzuki DF25A 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.

Suzuki DF25A 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.

 

Suzuki DF25A 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 DF25A Suzuki's 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.
