When navigating challenging waterways—such as shallow rivers, rocky shoals, or white-water rapids—a standard propeller system can pose significant risks to both equipment and safety. The advanced Yamaha Jet Drive 40 hp provides unparalleled freedom of movement by eliminating contact with the bottom while maintaining powerful performance.

This brand new Yamaha F40JEA jet drive is a state-of-the-art outboard motor designed for optimal maneuverability and reliable thrust. Fully rigged with an integrated jet pump assembly and equipped with a premium multi-function tiller handle, this Yamaha Jet Drive system is ready to enhance your boating experience.

Understanding the Power: The 40/30 Advantage

If you are exploring Yamaha’s advanced propulsion technology for the first time, you may encounter the "40/30" rating. This designation explains how this powerful motor operates and delivers superior performance in varied conditions.

• The 40 HP Powerhead: The core engine is a robust, three-cylinder Yamaha F40 powerhead (747cc). At the crankshaft level, it generates reliable 40 horsepower.
• 30 HP Jet Output: Because jet propulsion moves water through an intake and nozzle rather than using spinning blades, there is a natural efficiency difference. The actual thrust delivered at the pump output remains highly effective, providing strong shallow-water dominance comparable to a powerful 30 HP unit while retaining the torque of a larger engine class.

Key Features of the Yamaha F40JEA Outboard Motor

The design and technology packed into this outboard motor make it an ideal choice for boat owners seeking reliable, all-terrain performance.

Engine Performance & Technology

• Advanced Engine Design: Features a compact, lightweight 747cc SOHC three-cylinder engine.
