A REVOLUTION IN INNOVATION
The Word of the Day is “Excitement.” The DF115SS joins the Suzuki SS Series with an edgy Matte Black paint job and striking Red cowling graphics. This Fuel Injected 4 Stroke will deliver a powerful hole shot, strong mid-range punch and exhilarating top end. And your wallet will appreciate increased fuel economy with the Suzuki Lean Burn System. Bottom line, you won’t find more power, more advanced technology or a more compact package anywhere. Get on down to the local Suzuki Marine Dealer to be the first one on your block with a DF115SS.
The new DF115SS is ready to increase the fun factor wherever you take your boat. This Big Block DF115SS is based on an inline four-cylinder DOHC powerhead with 2,867cm³ (174.9 cu.in.) displacement, producing exceptional acceleration and torque. Available for both 20″ and 25″ transom, the DF115SS is ready for Bass Boats, Flats Boats, Bay Boats, Performance Pontoon Boats and just about any boat rated to handle this much fun. The question you have to ask yourself… Can you handle this much…fun? Well…can you?
WATER DETECTING SYSTEM
Water in the fuel can lead to problems that include poor combustion, lower power output, and corrosion. The Suzuki Water Detecting System is designed to help protect the engine from moisture in the fuel utilizing a water detecting fuel filter to alert the operator with both visual and audio warnings when water is present in the fuel. The filter is also designed to let you check for water visually.
2-STAGE GEAR REDUCTION SYSTEM
These outboards also incorporate two-stage gear reduction designed to take maximum advantage of the power produced by these high performance engines. Providing a final drive ratio of 2.50:1 the largest you can find in either of these outboard classes it delivers powerful torque for quick acceleration and great top-end speed.
ADVANTAGE
- High propulsive efficiency with large diameter propeller.
- Powerful navigation, maintaining propeller rotation even with a larger load.
- Power to turn large diameter propellers, offering quick acceleration
SUZUKI VVT (VARIABLE VALVE TIMING)
Variable Valve Timing is utilized on many of Suzuki’s high-end outboards to deliver high performance across the outboard’s full powerband while retaining the benefits that four-stroke technology provides. The system starts with an innovative cam profile designed for delivering maximum output and performance at high rpm. Variable Valve Timing is used to vary intake timing with the camshaft to optimize timing for low to mid-range operation. This allows the engine to deliver maximum power output across its entire operating range producing greater low to mid-range torque for powerful acceleration. The entire process happens automatically leaving you to enjoy the power and performance.
MULTI-STAGE INDUCTION SYSTEM
Getting the right amount of air into the cylinder has a great impact on performance. High-speed operation typically requires a greater volume of air, low-speed less. Suzuki’s Multi-Stage Induction system meets these needs by utilizing two intake manifold pipes per cylinder to ensure the engine gets the right amount of air. At low rpm, air enters the combustion chamber through a longer, curved manifold pipe designed to improve combustion and boost low-end torque. As rpm increases, the valves open on the direct intake pipes. Shorter and lacking resistance, these pipes allow a greater volume of air into the chamber, increasing the engine’s ability to breathe efficiently at high rpm resulting in higher power output during high-speed operation.
OFFSET-DRIVESHAFT
Pioneered by Suzuki, the use of the offset drive shaft on four-stroke outboards has long been utilized to reduce the size of the outboard. Found on all Suzuki four-strokes from the DF70A and up, this design positions the crankshaft in front of the drive shaft simultaneously moving the outboard’s center of gravity forward. While the design contributes greatly to the outboard’s overall compactness and increased power performance, it also moves the engine’s axis of inertia, the point where engine vibrations are at a minimum, up over the upper engine mount, thus greatly reducing vibration. These outboards also incorporate two-stage gear reduction designed to take maximum advantage of the power produced by these high performance engines. Providing a final drive ratio of 2.50:1—the largest you can find in either of these outboard classes—it delivers powerful torque for quick acceleration and great top-end speed.
SUZUKI LEAN BURN CONTROL SYSTEM
The Suzuki Lean Burn Control System is an intelligent fuel delivery system that achieves remarkable improvements in fuel consumption making fuel-efficient four-stroke outboards even more economical. Monitoring engine performance and operating conditions in real time, the system uses the 32-bit onboard ECM to predict fuel needs and deliver a leaner, more precise fuel mixture across the outboard’s operating range. The results show significant improvements in fuel economy across the entire powerband, including the cruising range where the engine is used a majority of the time.
TILT LIMIT SYSTEM
To protect the boat and motor from damage that can occur when tilting the motor, both outboards incorporate a user adjustable tilt limit switch that prevents the outboard from tilting beyond a predetermined point.
