2020 Yamaha 40 HP F40LA Outboard Motor
Reliability & Durability
- Corrosion Protection: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha Midrange four-stroke engines.
- Advanced Technology: The F40 and F30 are equipped with an Engine Control Module that interfaces with Yamaha Diagnostic System software. This provides a view of selected past and current running conditions, to help technicians provide a complete and accurate diagnosis of your engine.
- Protection from the Elements: A proven one-piece cowling with an intake air drain system easily and efficiently drains water away that enters the cowling. Incoming air is routed through a labyrinth of passages that help trap water before it enters the engine’s intake for maximum reliability.
- Cleaner Fuel: A large, on-engine water separating fuel filter with a water sensor is used in conjunction with the Yamaha optional boat-mounted 10-Micron Water Separating Fuel Filter. This helps separate water and contaiminants from the fuel before they can reach the outboard’s other filters and fuel injectors.
Convenience & Control
- Control and Comfort: Our optional, award-winning Multi-Function Tiller handle features a Variable Trolling RPM Switch (VTS®). It allows for precision trolling speed adjustments in 50-RPM increments. Compatible with all Midrange models.
- Easy Engine Flushing: A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.
- Power Trim and Tilt: Power trim and tilt models provide a trim range of -3 up to +20 degrees. This brings the bow of the boat up, for better hole shot and top speed and a smoother ride.
