Suzuki DF4AS4 Portable Outboard Motor

15" Shaft | Tiller Handle | Manual Start | Manual Tilt | 4 HP | Suzuki White

Go further than ever before.

The Suzuki DF4AS4 Portable Outboard Motor is a compact 4 horsepower four-stroke built for small boats where simplicity, low weight, and dependable operation matter more than extra bulk. With a 15" shaft and tiller handle steering, this model is a practical fit for jon boats, tenders, inflatables, and other lightweight hulls that need clean, controlled power without overcomplicating the setup. It is the kind of portable outboard that works well for quick trips to the dock, calm-water fishing runs, and everyday utility use.

What makes this engine appealing is how straightforward it feels in actual use. It is easy to handle off the boat, easy to clamp on, and easy to run without a learning curve. The 4-stroke design gives it a quieter, smoother character than many small portable engines, and the tiller layout keeps steering and throttle control right where you want them. For boaters looking for an efficient small outboard that is simple to live with and easy to transport, the DF4AS4 stays true to that role.
