NEXT GENERATION INLINE 4 CYLINDER OUTBOARD MOTORS Following a tradition of incorporating their most innovative technologies in all their outboards, Suzuki is proud to announce next-generation 150 and 175 horsepower outboard motors. Thanks to proven Suzuki systems and components, the new DF150A, 150SS and DF175A are now more powerful, more reliable and more fuel efficient than their predecessors. The DF150A and 175A are inline 4-cylinder engines with Big Block 175.0 cubic inch displacement. Weighing just 518 lbs. (20” shaft length), these new outboards feature Suzuki’s offset driveshaft engine layout, proven mechanical throttle and shift controls, and a powerful 2.29:1 gear ratio. Thanks to Suzuki’s Easy Start System, these new engines start with just one push of a button. “Our goal is to offer the boater the ultimate power solution for their boat and their kind of boating,” said Gus Blakely, Vice President of Sales for Suzuki Motor of America, Inc.’s Marine Division. “With these ‘next generation’ outboards we’re continuing to expand and improve our line of the Ultimate 4-Stroke Outboards.”
More Powerful
With their semi-direct intake system, high-performance 10.2-to-1 compression ratio, variable valve timing and multi-stage induction, the new DF150A, 150SS and DF175A generate approximately 3% more torque than the original models. This added torque pays off when powering todays larger, heavier bay boats, center consoles and pontoon boats.
Improving Reliability
Suzuki outboards are well-known for reliability, and the new DF150A and DF175A will only burnish that reputation. Combining high-quality components and exceptional skill in manufacturing and assembly, the new DF150A, 150SS and DF175A will now take advantage of onboard sensors that allow the engine to maximize operating performance under a wide range of conditions. An oxygen (O2) sensor improves efficiency by allowing the engine’s fuel injection system to best adapt to ambient conditions, and a new water detection system protects the engine should water contaminate the fuel system.

Outstanding Fuel Economy
A hallmark of these next-generation outboards has been Suzuki’s Lean Burn Control technology, which will now be available on all new DF150A and DF175A outboards. Onboard sensors monitor engine operating conditions and allow the engine’s ECM (Electronic Control Module) to predict fuel demand. Precise control of the engine’s fuel injection system by the ECM adjusts timing and provides the optimal amount of fuel, resulting in up to a 14% improvement in fuel economy when cruising.
