2027 Yamaha Four Stroke Midrange 1.8L F115LB3

Meet the 2027 Yamaha Four Stroke Midrange 1.8L F115LB3—finished in Yamaha Brown and built for boaters who want that “just right” blend of punch, efficiency, and day-in/day-out confidence in an engine-only package.
With 115 bhp (85.8 kW) on tap at 5500 RPM, this midrange Yamaha Fourstroke outboard is a sweet match for a wide range of 17–20' class hulls—think bay boats, multi-species fishing rigs, and runabouts that need strong midrange shove for getting on plane cleanly without stepping up into heavier, thirstier power. Its 1.8L (1832 cc) in-line 4-cylinder layout, DOHC valvetrain, and 16 valves (4 per cylinder) are all about delivering smooth, usable torque across the rev range, so the boat feels responsive when you roll into the throttle, pull skiers, or hop between spots with a loaded crew and gear.
At cruise, this platform is designed to make the most of regular gas thanks to fuel injection—helping you stretch your day on the water with steady, predictable fueling rather than constantly eyeing the gauge. And when conditions get real-world messy (chop, current, changing loads), the 2.15:1 gear ratio is set up to put that power to work through a propeller efficiently, translating engine muscle into practical acceleration and confident cruising.
For saltwater anglers, it’s salt water capable, and it’s also equipped with a visual/audible engine alert system plus emergency RPM reduction—smart safeguards that help you stay informed and protect the powerplant if something needs attention. Cooling is handled by water (open loop), and starting is simple with an electric starter.
This is the 20-inch shaft model, weighing in at 377 lbs (171 kg), with power trim for on-the-fly attitude adjustment and remote steering control compatibility—ideal for clean rigging on a variety of transoms and helm setups.
Warranty coverage is included through Yamaha’s factory warranty (confirm exact terms and start date with the dealer). If you’re looking for a capable, fuel-sipping midrange outboard with real-world thrust and Yamaha Brown style, this F115LB3 is ready to power your next repower or fresh build.
