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.
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.
An LED monitoring system provides engine operating status at a glance.
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).
*1: Emission standards compliancy is region specific.
*2: The EU emissions standards (exhaust gases and noise levels) set by the European Parliament and Council.
*3: According to in-house investigations as of February 2014.
