2027 Yamaha Four Stroke Midrange 1.8L F90LB2

Meet the 2027 Yamaha Fourstroke Midrange F90LB2—an engine-only listing that’s ready to bring modern, confidence-inspiring power to the kind of boats that live for early launches and long runs back to the ramp. Finished in Yamaha Pearl White, it looks as clean and purpose-built as it performs on the water.
At the heart of this midrange outboard is a 1.8L (1832cc) in-line 4-cylinder, 4-stroke design with 16 valves (SOHC, 4 valves per cylinder). That combination is all about smooth, usable torque and crisp throttle response—exactly what you want on aluminum fishing rigs, bay boats, and versatile multi-purpose hulls that need to hop on plane without drama, stay composed in chop, and carry a realistic load of people and gear. With 90 hp (67.2 kW) turning at 5500 RPM and a full-throttle range of 5000–6000 RPM, this setup is tuned to deliver strong midrange push where real-world boating happens.
Fuel-injected and happy on regular gas, the F90 helps keep cruise efficient and predictable—great for long days of exploring or trolling-and-running routines where you’d rather enjoy the ride than watch the fuel gauge. Water (open loop) cooling supports consistent operating temps, while a 35-amp alternator keeps power available for onboard needs as your day builds.
This is a salt-water-capable outboard with smart protection built in, including a visual/audible engine alert system and emergency RPM reduction for added peace of mind. Add in electric start, power trim, and remote steering control, and you’ve got an easy-to-live-with package that feels refined at the helm.
Built with a 20-inch shaft and a 2.15:1 gear ratio, it’s a great match for common transom heights and propeller-driven setups. Dry weight is 353 lbs—substantial enough for durability, balanced for many popular hulls.
