2025 Suzuki Marine DF115B Stealth X

This Fuel Injected Four-stroke delivers a powerful hole shot, a strong mid-range punch and an exhilarating top end. With the Suzuki Lean Burn System and increased fuel economy, this motor works with any budget. If you’re looking for power in a compact package, look no further.

Features may include:

• By positioning the crankshaft in front of the drive shaft, we’ve moved the outboard’s center of gravity forward, making the outboard more compact and increasing its performance. This design also significantly reduces vibration by moving the engine’s axis of inertia—the point where engine vibrations are at a minimum—up over the upper engine mount.

• The modern upswept design of the cover gives it an innovative look. But there’s more to it than just looks. Incorporated into the cowl is a semi-direct air intake system that delivers cooler air directly to the engine’s tuned multi-stage induction module, giving you greater acceleration and top-end speed. The design also reduces the temperature inside the engine with ports that allow the rotating flywheel to push warm air out.

• To guard against corrosion, Suzuki protects its outboards with its own specially formulated Suzuki Anti-Corrosion Finish. Applied directly to the outboard’s aluminum alloy, this finish provides maximum bonding of the finish to the aluminum surface. Layering an epoxy primer undercoat, black metallic finish, and clear acrylic fiber finish on top of this forms an effective treatment against corrosion.

• Suzuki’s Multi-Point Sequential Electronic Fuel Injection supplies each of the engine’s cylinders with an optimized mixture of fuel and air that is injected into the cylinder at high pressure. The system delivers improved fuel economy, crisp acceleration and reduced emissions that meet emissions regulations. It also conforms to the Recreational Craft Directive (RCD) Standards and has received a 3-star rating from the California Air Resource Board (CARB).
