Yamaha 70hp (F70AETL) is a lightweight and powerful SOHC 4-cylinder EFI engine that delivers excellent acceleration and low fuel consumption. PrimeStart™, TCI ignition, electric trim and tilt, and variable trolling speed control make operation easy and precise. A quiet and reliable engine for versatile boating.

Yamaha 70hp (F70AETL) is one of the lightest and most versatile 70-horsepower four-stroke engines on the market. Its SOHC 4-cylinder EFI design delivers excellent power and torque relative to its weight, making the engine an ideal choice for light and medium-sized boats that require quick acceleration, fuel efficiency, and quiet operation. The 996 cm³ displacement delivers strong low-end torque that gets the boat up on plane quickly, even when loaded.

Yamaha’s EFI system ensures clean combustion, low fuel consumption, and instant throttle response without any jerking. PrimeStart™ makes starting as easy as turning a car key, and electric trim and tilt provide precise control at all speeds and in all conditions. The engine’s lightweight construction and optimized exhaust system reduce noise and vibration, improving ride comfort even on long trips.

TCI microchip ignition ensures reliable starting and smooth operation, and a powerful AC alternator keeps the boat’s electrical systems running even at low RPMs. Digital network gauges provide a clear view of speed, fuel consumption, trim, and engine status. The optional Y-COP immobilizer locks the engine via remote control and prevents unauthorized starting attempts.

Variable trolling speed control allows for fine-tuning the speed in 50-rpm increments, making the F70 an excellent choice for anglers and situations requiring precise speed control. Its lightweight construction, quiet operation, and Yamaha’s renowned reliability make this motor a long-lasting and versatile companion for all types of boating.
