Suzuki DF4A Portable Outboard Motor 2025 – 4HP Four Stroke

Suzuki DF4A 2025: The Lightweight 4HP Benchmark Continues

The 2025 Suzuki DF4A keeps the formula that made it a portable favorite: a 138cc single-cylinder OHV four stroke at 51.8 lbs (15″) / 54 lbs (20″), with the overhead 1.2L gravity-feed tank for instant starts after storage, an offset crankshaft for reduced vibration, a first-in-class oil filter, and three-way leak-free storage. Digital CDI with over-rev limiter, two-position shallow water drive, freshwater flush, 180° steering, and a rubber-mounted tiller finish a thoroughly refined package in the small horsepower class.
