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.
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.
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 rotation 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's highly efficient four-stroke technologies produce lower emissions that allow outboards like the DF25A 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).
