Suzuki's new lightweight DF25A/30A
Lightest and leanest in their class. The best 25/30 horse ever?Suzuki Marine has announced the introduction of two new models to its lightweight line up: DF30A/25A four-stroke outboards with the impressive claim that they are the lightest four-stroke outboards available in their respective class.
The models available include DF25AS, DF25AL, DF25ATHL, DF25ATL, DF30ATHL, DF30ATL, DF30AQHL. The first of these is likely to be displayed during this year's capital-city boat show season.
Here are some of the standout features and benefits of the new outboards:
- Lightest in Class. Featuring some of Suzuki’s best technologies, the DF30A/25A are the lightest outboards available in the 22kW (30PS)/18.5kW (25PS) four-stroke outboard class.
- First In Class With Roller Rocker Arms. These are the first outboards in their respective classes to utilise 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.
- Suzuki Lean Burn Control System. This intelligent fuel-management system predicts fuel needs by monitoring engine performance and operating conditions to deliver a leaner mixture. The result is remarkable improvements in fuel economy.
- Easy Start Recoil. Fuel injection delivers easier starts, but Suzuki says it goes a step further using a very light recoil starter that requires less pull strength. This starter makes it exceptionally easy for nearly everyone to operate making the outboard quicker and easier to start.
- 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 vent warm air from the recoil cover, inner air intake, and engine head cover outside, reducing temperatures inside the head cover.
- 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 better acceleration in all conditions, says Suzuki.
