JET DRIVEShallows. Rocky-bottom rivers. Shoals. White-water rapids. They’d all prove treacherous for a propeller-driven outboard, but Yamaha’s Jet Drive outboards are all about it. Available in 150, 115, 60 and 40 horsepower, you can “off-road” without the possibility of breaking a blade on rocks or other underwater obstructions. So, while you may be giving up the prop, you’re gaining a whole lot of freedom with a jet drive.
Our 747-cc F40 Jet Drive outboard produces 30 hp at the pump. Its compact, lightweight SOHC three-cylinder, in-line design features a long-track induction system and a single throttle valve. This creates compact, light-weight power and improves throttle response for shallow streams.
Features may include:
- 219 pounds (including jet pump assembly)
- Fits 20-inch transom boats
- Solid 16-amp alternator
- Nitro Assist Tilt
