2018 Suzuki Marine 4 HP DF4A Outboard Motor

The DF4A is built around a compact OHV 2-valve design that prioritizes portability without sacrificing performance. At just 55 lbs (25 kg), it’s among the lightest outboards in its class, making it genuinely easy to lift, mount, and remove from your boat . The engine features two carrying handles — a front handle that’s deep and ergonomic, plus a rear handle — for balanced transport .

One of the DF4A’s most practical features is its ability to be stored in three different positions (on either side or on the rear) without oil spilling — a genuine convenience for boaters who store their motors in garages, sheds, or vehicle trunks between outings . The engine also features a new tilting system with three positions and an easy-to-find lever, making tilt adjustments simple .

The DF4A’s dropping fuelling system makes restarting easy after long periods of storage — you don’t need to refill the fuel tube before starting . The engine also includes a fresh water flushing port for simplified maintenance after saltwater use.

The 4 HP portable outboard segment is competitive, with strong offerings from Mercury 4 FourStroke, Yamaha F4, and Honda BF4. Here’s how the DF4A compares on the specifications that matter:

The DF4A matches or beats competitors on weight while delivering Suzuki’s industry-leading 5-year manufacturer warranty . Its three-position storage capability is a genuine practical advantage over competitors that can only be stored on one side .

The DF4A is well-suited to a wide range of American boating applications:

• Canoes and kayaks — lightweight and portable for paddle-craft auxiliary power

• Small fishing boats and jon boats — reliable four-stroke power for calm-water fishing

• Tenders and dinghies — easy to stow and mount on larger vessels

• Duck boats — quiet operation and compact size for hunting applications

The engine features a 90° steering angle on both right and left sides for excellent maneuverability . The gear lever is positioned opposite the throttle grip with three positions (Forward–Neutral–Reverse), and the steering friction adjuster lets you dial in the desired feel .
