Suzuki 140HP DF140A L – 4-Stroke 20in Shaft

Suzuki 140HP DF140A L 4-Stroke Long Power

Featuring an industry-proven 2045cc four-cylinder engine family, the Suzuki 140HP DF140A L serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability and refined displacement. This 140HP four-stroke technology utilizes a 16-valve DOHC architecture and Suzuki’s Lean Burn Control to maximize mechanical efficiency and fuel induction stability for large aluminum fishing boats and fiberglass skiffs. The 20-inch long shaft design provides an optimized center of gravity, while the multi-port Electronic Fuel Injection (EFI) and electric start ensure immediate, reliable ignition across diverse inland and coastal environments.

Operational longevity of the DF140A L model is secured through a specialized pressurized lubrication system featuring an offset driveshaft to maintain internal cleanliness and reduce mechanical vibration. To facilitate easy after-storage starts, the unit employs a sophisticated induction system paired with a 40A alternator for accessory maintenance, while the Suzuki Anti-Corrosion Finish utilizes a multi-layer finish to mitigate oxidation in high-salinity waters. With a 3-year/300-hour service interval and legendary reliability, this high-performance outboard provides superior ownership value for boaters seeking professional-grade power and quiet operation.
