Meet the Yamaha 70HP—where high-tech meets high seas. Designed to be light, powerful, and incredibly efficient, this four-stroke outboard redefines what mid-range performance means. Whether for work or weekend, this is the engine that lets you do more.
70HP
Light. Strong. Ready.
Yamaha’s 70HP outboard is the lightest 4-stroke in its class—perfect for powering medium-sized boats with refined confidence. Thanks to its SOHC 4-cylinder design, Electronic Fuel Injection (EFI), and advanced intake/exhaust systems, it delivers exceptional acceleration, smooth throttle response, and reduced emissions. The result? Outstanding performance with fuel savings to match.
This engine is also smart. Compatible with Yamaha’s Digital Network Gauges, it provides real-time readouts of RPM, trim angle, fuel economy and more. Trim and tilt are electric and smooth. And with optional features like the Y-COP engine immobilizer and Variable Trolling RPM control, the 70HP is ready for both security and precision handling. Built to go far. Built to last.
