Yamaha 40hp Jet Drive Outboard Motor 20" Shaft Standard Rotation White F40JEHA

This 40hp jet drive marine outboard motor is designed for shallow-water and obstacle-rich marine environments. It features a 20" shaft with standard rotation, providing reliable propulsion for vessels operating in shallows, rocky-bottom rivers, shoals, and white-water rapids. The powerplant is a 747cc jet drive four-stroke engine with 3 cylinders, utilizing electronic fuel injection (efi) for optimal combustion efficiency and throttle response.

Propeller-free operation eliminates the risk of propeller damage on submerged obstructions, making this unit ideal for rivers and areas with submerged debris. The jet drive system delivers approximately 30hp at the pump, translating engine power into effective thrust for shallow-draft vessels. A freshwater flush device facilitates convenient engine flushing after operation in saltwater, supporting extended service life.

Long-track induction enhances airflow and volumetric efficiency for improved throttle response. SOHC valve train architecture optimizes volumetric efficiency and contributes to lighter overall weight. A safety lanyard provides an emergency engine shutoff mechanism for enhanced operator protection.

The nitro assisted tilt system allows for quick adjustment of engine angle, optimizing running attitude under varying load and water conditions. An electric starter system ensures reliable engine ignition in all operating environments. With a dry weight of approximately 227 pounds, this outboard balances thrust output with manageable installation requirements.

Finished in white, this outboard complements a variety of hull colors and exterior styling preferences. This engine is backed by the manufacturer’s limited warranty, subject to the terms and conditions specified by the manufacturer. Intended for use on registered watercraft, this propulsion system is suitable for recreational boating in shallow and obstacle-rich waterways.

Key technical characteristics include four-stroke architecture, electronic fuel injection, and jet drive propulsion. Professional installation by a qualified marine technician is recommended to ensure proper alignment, rigging, and calibration for optimal performance and service life. This product is classified as a marine propulsion engine and is intended for use on registered watercraft in compliance with applicable maritime and environmental regulations.
