⚓ Marine Equipment Specialist: Yamaha Jet Drive Authority.
Verified technical data for shallow-water remote operations. This F40JEA model is configured for remote steering and throttle, ideal for jet-ready hulls.
The Yamaha F40JEA is a 747cc three-cylinder jet drive outboard designed for remote-steer boat configurations. By utilizing a high-velocity jet pump instead of a propeller, it allows for safe navigation in water only inches deep, where rocks and sandbars would destroy a standard gearcase. Built on Yamaha's proven 40hp EFI powerhead, it produces 30hp at the jet nozzle, providing the specific power-to-weight ratio needed for aluminum river boats and shallow-draft vessels.

Frequently Asked Questions
1. How does the F40JEA (Remote) differ from the F40JEHA (Tiller)?
The F40JEA is designed for boats with a steering wheel and console. It does not include a tiller handle, requiring external steering and throttle cables for operation.
2. What height should the transom be for this 20" jet motor?
Jet outboards require the intake to be flush with the bottom of the hull. For a 20" shaft model, a 20-inch transom is standard, but the jet foot must be properly positioned to avoid air intake (cavitation).
