Suzuki DF20AS4 Portable Outboard Motor

15" Shaft | Tiller Handle | Manual Start | Manual Tilt | 20 HP | 97 Lbs | Nebular Black

Light on weight. Light on compromise.

The Suzuki DF20AS4 Portable Outboard Motor is a practical 20 horsepower four-stroke designed for small boats that want more serious performance while keeping the rig simple. With a 15" shaft, tiller handle steering, and portable-friendly layout, this model is a dependable choice for jon boats, skiffs, aluminum fishing boats, and utility craft that need direct stern control and enough horsepower to move a load with confidence. It stays simple to operate, but it carries more authority than the smaller end of the portable range.

That extra thrust is what makes a 20 HP tiller outboard so useful in real conditions. It helps with planing, improves response when the boat is carrying gear or passengers, and gives the operator better control in wind, current, or tight maneuvering situations. The tiller setup keeps steering immediate and straightforward, which many small-boat owners still prefer. For a buyer who wants a clean, no-nonsense short-shaft outboard with enough muscle to feel genuinely capable, the DF20AS4 is built for that role.
