Suzuki DF140B – 140 HP High-Performance Outboard Motor

The DF140B is a 140 HP four-stroke outboard that packs a serious punch while remaining impressively light and compact. This engine is well-suited for boaters who need extra performance – whether on a fast pleasure craft, a fishing boat loaded with gear, or even a work boat – without adding unnecessary weight. Thanks to Suzuki’s engineering, the DF140B achieves best-in-class power-to-weight, giving your boat lively acceleration, excellent top-end speed, and nimble handling on the water. Its 2.0-liter inline-4 “big small-block” design delivers the kind of heavy-duty, dependable power usually found in larger engines, yet it’s tuned for smooth, quiet operation and easy maintenance, making it equally at home on calm lakes or choppy offshore waters.

Suzuki has equipped the DF140B with an array of advanced features to ensure it not only performs, but also excels in efficiency and reliability. The engine is built with Suzuki’s Lean Burn Control system, which optimizes the fuel-air mixture for outstanding fuel economy and reduced emissions across the operating range – boaters will notice lower fuel bills and extended range for each tank. The motor’s cowling includes a large air induction port to maximize airflow, feeding the engine plenty of oxygen for maximum combustion and muscle. Maintenance is straightforward: an Easy Access oil filter (located right under the top cover) and an Oil Spill Catcher tray make oil changes cleaner and simpler. The DF140B also shares the class-first option of mechanical or drive-by-wire controls, so it can be rigged traditionally or with Suzuki’s Precision Control for effortless throttle and shift. To protect itself during hard use, this model features an improved gear case design for better oil circulation and durability, along with Suzuki’s Water Detecting System to warn of water in the fuel before it can cause harm. A Tilt Limit System is included to prevent over-tilting accidents. Like all Suzuki outboards, the DF140B uses a self-adjusting timing chain and is treated with Suzuki’s anti-corrosion finish, ensuring long-term reliability and a long life in harsh marine environments.
