Suzuki Marine 15 HP DF15AS2 EFI Outboard Motor

Description

The DF15AS2 incorporates technology that’s genuinely unique in its class. Suzuki’s engineers completely redesigned fuel injection system components — including the high-pressure fuel pump, fuel cooler, vapor separator, and injectors — to be smaller and lighter than any previous system, making battery-less EFI possible in this horsepower class . The result is quicker, easier starts without the bulk and weight of a battery.

The Lean Burn Control System continuously monitors engine performance and operating conditions to predict fuel needs and deliver a leaner fuel-air mixture, resulting in significant fuel savings across the entire operating range . This isn’t marketing language — it’s a measurable advantage for boaters facing rising fuel costs.

The DF15AS2 is the lightest outboard in its class at just 97 lbs (44 kg), matching or beating competitors on weight while delivering Suzuki’s industry-leading warranty . The engine also features decompression release for easy starts, a fresh water flushing port for simplified maintenance, and multi-layer corrosion protection designed specifically for saltwater environments .

The 15 HP portable outboard segment is competitive, with strong offerings from Mercury 15 FourStroke, Yamaha F15, and Tohatsu MFS 15E. Here’s how the DF15AS2 compares on the specifications that matter:

The DF15AS2 is among the lightest outboards in its class, making it noticeably easier to handle, transport, and mount than competitors . Its battery-less EFI system is a genuine industry first, eliminating battery maintenance and reducing overall system weight .

The DF15AS2 is well-suited to a wide range of American boating applications:

• Jon boats and skiffs — lightweight design and reliable power for fishing 

• Inflatables and tenders — portable enough for easy transport and storage

• Sailboat auxiliary power — dependable thrust for docking and maneuvering

• Small aluminum boats — excellent power-to-weight ratio for planing

The engine features a forward-mounted gear shift lever for easy operation, a twist-grip throttle with tension control, and shallow water drive capability for navigating shallows .
