Suzuki’s New 350 On The Water

First Look: Suzuki Introduces 350 HP V6 4-Stroke Outboard. Suzuki’s New 350 HP V6 4-Stroke Flagship Model Outboard, The DF350A Features Innovative Contra-Rotating Propellers And More Exclusive Features Suzuki Marine, a leader in 4-stroke outboard technology and performance, is proud to introduce its newest model, the DF350A. At 350 horsepower, this V6 4-stroke is the largest, most powerful outboard Suzuki has built to date. “We took the time and effort to build a powerful new outboard that really matches the trend towards bigger boats,” said Gus Blakely, Vice President of Marine Sales for Suzuki Motor of America, Inc. “Whether you’re talking 40-50 foot center consoles or even the new breed of runabouts, deck boats and cruisers, Suzuki can now deliver the power, performance and ease of use boat builders and their customers are asking for.” 350 Horsepower And A 12.0:1 Compression Ratio Suzuki engineers achieved 350 horsepower while still designing a compact, lightweight powerhead. A unique combination of cool air intake, dual fuel injectors and a strengthening of the pistons has virtually eliminated engine knock, a typical by-product of high compression engines. Suzuki Dual Prop System While contra-rotating propellers are not a new technology, they have never been successfully used on 4-stroke outboard motors until now. Contra-rotating propellers also provide added surface area, for more stability and increased “traction” or grip underwater. “When we say ‘Ultimate 4-stroke’ we mean it in every way – performance, reliability, dependability, even superior fuel economy.” The DF350A features Suzuki Precision Control, drive-by-wire throttle and shift controls. Two-stage gear reduction provides a larger reduction gear ratio (2.29:1) and more torque for quick acceleration, and improvements in top speed, as well.

Suzuki’s New 350 HP V6 4-Stroke Flagship Model Outboard, The DF350A Features Innovative Contra-Rotating Propellers And More Exclusive Features

Suzuki Marine, a leader in 4-stroke outboard technology and performance, is proud to introduce its newest model, the DF350A. At 350 horsepower, this V6 4-stroke is the largest, most powerful outboard Suzuki has built to date. In development for more than three years, it represents a significant milestone in both engineering and design.

“We took the time and effort to build a powerful new outboard that really matches the trend towards bigger boats,” said Gus Blakely, Vice President of Marine Sales for Suzuki Motor of America, Inc. “Whether you’re talking 40-50 foot center consoles or even the new breed of runabouts, deck boats and cruisers, Suzuki can now deliver the power, performance and ease of use boat builders and their customers are asking for.”

350 Horsepower And A 12.0:1 Compression Ratio

Suzuki engineers achieved 350 horsepower while still designing a compact, lightweight powerhead. The robust engine displacement of 4.4 liters is matched by a high-performance 12.0:1 compression ratio, the highest ever for a production outboard engine. A unique combination of cool air intake, dual fuel injectors and a strengthening of the pistons has virtually eliminated engine knock, a typical by-product of high compression engines.

Suzuki Dual Louver System, Direct Air Intake

Suzuki engineers have designed an air intake system that allows the engine to draw in ample fresh air, while separating out water, spray and moisture. Dual louvers under the hood trap larger water droplets and then moisture as it enters the engine cowling, resulting in zero water intake during testing. In addition, intake air temperatures are, on average, 10º cooler than ambient, providing the combustion chamber with cooler, denser air for a more powerful cycle.

Dual Injectors

Two, smaller fuel injectors allow for precise injection of fuel to the center of the combustion chamber, which avoids off-center combustion – a major cause of knocking. In addition, because 100% of the fuel is injected into the cylinder at once, a degree of cooling is also obtained, providing up to 3% additional power without causing knocking.

Advanced Piston Technology

To achieve 350 horsepower, the surface of the piston needs to withstand added forces. In order to assure both performance and long life, Suzuki engineers switched from a standard heat treatment to “shot peening.” Shot peening, a more expensive process, creates fine dimples in the face of the piston that evenly distribute the pressure created during combustion. In addition, the connecting rods and hardware have been strengthened to handle the added loads.
