The DF150 stealth is a 150-horsepower four-stroke outboard designed for boaters who want strong hole shot, mid-range punch, and top-end speed without sacrificing fuel economy.
Multi-Point Sequential Electronic Fuel Injection delivers an optimized fuel-air mixture to each cylinder at high pressure, resulting in crisp acceleration, improved efficiency, and reduced emissions. It meets RCD standards and carries a 3-star CARB rating. Suzuki’s Lean Burn System works alongside the fuel injection to extend range across varying throttle conditions.
The crankshaft is positioned forward of the drive shaft, moving the center of gravity ahead for a more compact footprint and reduced vibration. The axis of inertia aligns with the upper engine mount, keeping the ride smooth at all speeds.
The upswept Stealth cowl features a semi-direct air intake that routes cooler air into the engine’s multi-stage induction module for improved acceleration and top-end output. Integrated ports allow the flywheel to push warm air out of the engine compartment. For corrosion protection, Suzuki applies its Anti-Corrosion Finish directly to the aluminum alloy — an epoxy primer undercoat, black metallic finish, and clear acrylic fiber topcoat layered for maximum adhesion and durability.
