2023 DF140B Outboard Motor

The all new Suzuki DF140B is light and compact but delivers inspired performance, giving it the best power-to-weight ratio in its class along with mechanical or digital controls. The DF140B Suzuki outboard motor provides heavy-duty performance and long-lasting durability in a revolutionary, lightweight package, with our engine cover design that features a large air induction port to provide maximum airflow and maximum muscle.

Enjoy easy maintenance thanks to our Easy Access Oil Filter that an be replaced by simply removing the top cover, an Oil Spill Catcher that we’ve added to catch oil that spills when changing the oil filter, and an Oil Level Gauge that can use a Φ15 oil changer hose.

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.

Our Lean Burn intelligent fuel management system predicts fuel needs by monitoring engine performance and operating conditions to deliver a leaner fuel mixture to the engine. The result: remarkably improved fuel economy that the environment—and your wallet—will love.
