2017 Yamaha Outboards Jet Drive Four Stroke F40

Jet Drive Four Stroke F40

The adventure begins the second you start up a Yamaha Jet Drive four stroke. Propeller-free and powerful, these nimble four strokes boldly go where no conventional outboard would dare. Skinnies. Shallows. Rocky-bottom rivers. Sandbars. Shoals. Rapids. They'd all prove treacherous for a propeller driven outboard, but a jet drive is all over it. Lightweight, versatile and quiet, our jet drive four strokes come in a wide range of horsepower options to fit your boat and application. Think of them as the SUV of outboards.
