2018 Yamaha Marine Jet Drive 40 hp 2018 Yamaha Marine Jet Drive 40 hp Yamahas Jet Drive four strokes, can boldly go where no propped outboard would dare. Shallows. Rocky-bottom rivers. Shoals. White-water rapids. Theyd 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, youre gaining a whole lot of freedom, with powerful, fuel efficient Yamaha Jet Drives available in 150, 115, 90, 60 and 40 horsepower. Our 747-cc F40 Jet Drive four stroke produces 30 hp at the pump. Its compact, light-weight 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. Features may include: Compatible with mechanical controls, our Multi-Function Tiller Handle, analog gauges and Command Link® 219 pounds (including jet pump assembly) Fits 20-inch transom boats Solid 16-amp alternator Nitro Assist Tilt FUEL ECONOMY Precision Multi-Point Electronic Fuel Injection delivers the exact amount of fuel needed for optimum performance and efficiency. Yamahas EFI optimizes fuel atomization further enhancing fuel economy. LIGHTWEIGHT, COMPACT DESIGN Single or Double Overhead Camshaft platforms provide lighter weight, impressive acceleration and better fuel efficiency. INCREDIBLE MANEUVERABILITY Microcomputer Ignition adjusts timing to maintain optimum engine performance, economy and power under all conditions. POWERFUL HOLE SHOT The Composite Intake Manifold on Yamaha's Jet Drive F150, F115, F90, F60 and F40 feature long tube intake tracks, tuned to increase airflow. This boosts low-end and midrange torque for a more powerful hole shot and increased acceleration. Even with all this responsive power, an air silencer box and surge tank reduce air intake noise and air turbulence for smooth, quiet operation. OPTIMUM PERFORMANCE Microcomputer Ignition adjusts timing to maintain optimum engine performance, economy and power under all conditions. INCREDIBLE MANEUVERABILITY With no gearcase or propeller extending below the hull, a jet drive allows you to maneuver around or pass over obstructions that would limit the travel of a conventional propeller-driven outboard. And with electronic multi-point fuel injection, you get lots of responsive power with fuel-sipping efficiency.
