Buy New Yamaha F70 70HP 4 Stroke Long Shaft Outboard Engine Online
The new Yamaha F70 70HP 4 Stroke Long Shaft Outboard Engine delivers class-leading performance for boaters in the United States and across Europe. Its advanced powerhead features a single overhead camshaft (SOHC) with four valves per cylinder, increasing total intake valve area by 17% while reducing piston and valve weight by up to 10% compared to the T60 model. This engineering breakthrough provides substantially more horsepower-per-liter of displacement than any competing outboard – whether four-stroke or two-stroke direct-injected.
This engine is the lightest in its class at just 115 kg (253 lbs) dry weight – even lighter than competitive two-stroke direct-injected outboards. From the specially designed engine block to the two-piece upper case, every ounce is optimized for performance without sacrificing durability. Precise throttle control routes all intake air through a single throttle valve, then through individual long intake tracks that are pulse-tuned for optimal air density and timing, maximizing both power and fuel efficiency.
