Discover Power and Efficiency with the Suzuki DF115B Stealth X Outboard Motor

The new 2026 Suzuki Marine DF115B Stealth X represents a pinnacle of marine engineering, combining exceptional performance with industry-leading fuel efficiency. This powerful four-stroke outboard motor is engineered to deliver more than just horsepower; it provides an exhilarating boating experience that adapts seamlessly whether you need immediate thrust or sustained cruising power.

Optimized Performance for the Ultimate Boating Experience

From its initial start, this Suzuki outboard delivers a potent hole shot. The DF115B Stealth X is renowned for its strong mid-range punch and exhilarating top end speed, ensuring that every outing on the water feels powerful and responsive. As a fuel-injected four-stroke motor, it combines robust performance with advanced technology designed to work efficiently across various marine budgets.

Advanced Design Features Enhance Performance

Suzuki Marine has incorporated several key design advancements into this model, maximizing both efficiency and handling:

• Center of Gravity Optimization (Positioned for Greatness): By strategically positioning the crankshaft forward relative to the drive shaft, we have moved the outboard's center of gravity. This innovative setup makes the entire unit more compact while significantly boosting overall performance characteristics.
• Vibration Reduction: The advanced engine design also moves the axis of inertia—the point where vibrations are minimized—upward over the upper engine structure. This results in a noticeably smoother and less fatiguing ride for operators, even during extended use.

Smart Technology Meets Durability

The DF115B Stealth X is not only built to perform but also designed with intelligence and longevity in mind.

Improved Efficiency and Emissions Control

Fuel economy remains a top priority. Suzuki’s Multi-Point Sequential Electronic Fuel Injection system delivers an optimized, high-pressure mixture of fuel and air directly into each cylinder. This advanced fueling process results in: improved overall fuel efficiency, crisp acceleration response, reduced emissions that meet strict regulations (including adherence to the Recreational Craft Directive standards), and a strong rating from governing bodies like CARB.

Innovative Cooling and Aesthetics

Beyond its modern upswept cover design—which provides an innovative aesthetic appeal—the motor incorporates critical functional elements. A semi-direct air intake system delivers cooler, optimized airflow directly to the engine's multi-stage induction module. Furthermore, specialized ports allow warm exhaust air to be efficiently expelled from the engine chamber, helping maintain optimal operating temperatures and enhancing top-end speed.

Built for Marine Environments (Corrosion Protection)

Protecting your investment is paramount when using a high-performance outboard motor. Suzuki addresses corrosion proactively with its specialized Anti-Corrosion Finish. This comprehensive treatment involves layering an epoxy primer undercoat, followed by a black metallic finish and topped with clear acrylic fiber. This multi-layered process ensures maximum bonding adhesion to the aluminum alloy structure, providing superior protection against harsh marine elements.
