2025 Yamaha Marine Jet Drive 40 HP

JET DRIVE

Shallows. 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
