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. Located in an easily visible position, the LEDs provide easy to understand monitoring at a glance so you can enjoy a pleasurable boating experience. The LED monitoring system utilizes three LEDs to keep you informed of current operating conditions. Requiring less pull strength, the Easy Start Recoil Starter makes starting the outboard quick and easy. Easy Start RecoilДЇuel injection delivers easier starts, but Suzuki goes a step further incorporating a very light recoil starter into these outboards. The result is smoother piston movement, which improves operating efficiency. 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 roller changes contact between the camshaft and rocker arm from a conventional sliding action to a rolling action reducing friction in rocker arm operation. 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 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. This, together with a newly designed air cleaner allows higher power output from a small displacement. Direct Intake And Engine Cover VentilationДЄ new engine cover design provides the direct intake system with a smoother, cooler flow of air boosting engine operating efficiency. The result is remarkable improvements in fuel economy. This intelligent fuel management system predicts fuel needs by monitoring engine performance and operating conditions to deliver a leaner fuel mixture to the engine. What's more, it operates without a battery and still delivers quicker starts, smoother operation, and more acceleration in all conditions.

*4:According to in-house investigations as of February 2014 New Generation Fuel Injection System (Battery-Less Fuel Injection)ДЄ remarkably compact and lightweight fuel injection system is designed to fit into these outboards without adding unneeded bulk or weight. 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.
