Yamaha F40 Jet Drive 747cc 4-Stroke (30HP at the Pump) — Jet Outboard for Shallow Water & Rough Terrain
Yamaha Jet Drive F40: Prop-Free Freedom for Rivers, Shoals & Rapids
Experience bold, prop-free performance with the Yamaha F40 Jet Drive—a 747cc 4-stroke jet outboard designed to go where a conventional prop outboard can’t. Perfect for shallow water, rocky-bottom rivers, shoals, and white-water conditions, the jet drive’s no propeller design helps you reduce damage risk from underwater obstructions while delivering strong throttle response thanks to a compact, lightweight SOHC 3-cylinder in-line setup with EFI fuel injection and long-track induction. Key benefits include incredible maneuverability (no gearcase/prop below the hull), easy freshwater flushing for convenience and extended engine life, and Yamaha’s durability technology using Phaze Five™ anti-corrosive paint with a tough five-layer barrier against corrosion (standard on Yamaha Jet Drive 4-stroke models). The F40JEHA features electric start, CDI microcomputer ignition, jet nozzle exhaust, wet sump lubrication, and a direct-drive system with forward/neutral/reverse, plus a safety lanyard and owner’s manual included.
