Yamaha Jet Drive 150 / 115/ 90 / 60 / 40 HP
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.
Make an appointment with Tom Ross to come in and see these motors in person.
Fuel Economy
Precision Multi-Point Electronic Fuel Injection delivers the exact amount of fuel needed for optimum performance and efficiency. Yamaha’s 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.
