Description
Meet the 2026 Yamaha F70LB3—finished in Yamaha Brown and ready to turn your favorite hull into a confident, efficient runner. This is an engine-only listing (no boat included), perfect for repower projects or new builds where you want modern four-stroke performance without jumping into heavyweight horsepower.
Built as a midrange, inline 4-cylinder, 4-stroke outboard, this 1.0L (996cc) platform delivers 70 bhp (52.2 kW) at 5800 RPM, with a full-throttle operating band of 5300–6300 RPM. That power level is a sweet spot for a wide range of practical boats—think smaller center consoles, aluminum fishing rigs, bay boats, and utility hulls that need crisp acceleration onto plane without overwhelming the transom. The 2.33:1 gear ratio helps translate that power into real-world push, especially when you’re loaded with fuel, gear, and passengers.
At cruise, the fuel-injected setup is designed for easy ownership and sensible fuel use—great for long days of exploring, trolling, or making repeat runs between spots—while still sipping regular gas. Cooling is handled by a water (open loop) system, and the 16-valve SOHC cylinder head (4 valves per cylinder) helps the engine breathe efficiently across the RPM range.
This F70LB3 comes with a 20-inch shaft and remote steering control, making it an excellent match for many standard transoms and helm layouts. Power trim lets you fine-tune running attitude for changing chop, load, or speed, and electric start keeps your departures quick and simple. With an alternator rated at 15 amps, you’ve got charging support for the essentials on typical day-use setups.
For peace of mind, it’s salt water capable and includes a visual/audible engine alert system plus emergency RPM reduction—valuable safeguards when conditions change or something needs attention. Dry weight is a manageable 253 lbs (252 lbs for the 20-inch shaft spec), keeping the package balanced for hulls that benefit from midrange power without excessive mass.
Want a dependable, modern 70-horse outboard in Yamaha Brown that’s sized right for versatile coastal and inland boats? The Yamaha F70LB3 is ready to bolt on and get you back on the water. Warranty coverage applies—ask us for the exact details and terms available with this new engine.
