Yamaha’s Jet Drive four strokes, can boldly go where no propped outboard would dare. Shallows. Rocky-bottom rivers. Shoals. White-water rapids. They’d all prove treacherous for a propeller-driven outboard, but a jet drive is all over it. Prop-free, you can “off-road” without worrying about breaking a prop on rocks and other underwater obstructions. So, while you may be giving up the prop, you’re gaining a whole lot of freedom, with powerful, fuel efficient Yamaha Jet Drives available in 150, 115, 90, 60 and 40 horsepower.
Our 1.8-liter F115 Jet Drive four stroke produces 80 hp at the pump. Its compact, light-weight DOHC design features 16-valves with four valves per cylinder and long tube intake tracks. This produces ample power for deck boats and deep-V hulls navigating shallow, rocky rivers.
