Suzuki DF25AS / ATL Short and Long Shaft Outboard Engine

Suzuki DF25A 

DF25A Lean Burn

Lightest in class outboard packed with Suzuki technology
Our engineers have packed the new in-line three-cylinder DF25A with some of Suzuki’s finest technologies giving it class-leading advantages that put it ahead of the rest. Engineering lightweight outboards has long been a Suzuki hallmark so in keeping with that, the DF25A is the lightest outboard in the 25hp class. It is the first in class to feature friction reducing roller rocker arms and to utilise an offset crankshaft to achieve smoother operation and greater mechanical efficiency. Fuel is supplied with our Lean Burn Control system and a Battery-Less Fuel Injection system that gives these outboards remarkable improvements in fuel efficiency while maintaining excellent power and performance. An LED monitoring system also provides engine operating status at a glance.
