2027 Yamaha Four Stroke Midrange 1.8L F115LB

Meet the Yamaha Fourstroke F115LB: a midrange, 1.8L in-line 4 outboard that’s built to make everyday boating feel effortless. Finished in classic Yamaha Gray, this engine-only listing is a smart match for a wide range of 20-inch transom setups—think bay boats, center consoles, aluminum fishing rigs, and pontoons that want confident punch without jumping to a heavier, higher-horsepower class.
With 115 bhp (85.8 kW) at 5500 RPM, this Four Stroke delivers the kind of torque that helps a loaded hull climb on plane cleanly and stay there comfortably. The DOHC, 16-valve design (4 valves per cylinder) lets the engine breathe efficiently across the rev range, so acceleration feels crisp when you’re pulling away from the dock, bumping up to cruise, or working through chop.
Fuel economy is where this package really shines for real-world use. Fuel injection keeps starts quick and response smooth, and it’s designed to run on regular gas, which is a win for both convenience and operating cost. Settle into an easy cruise and you’ll appreciate how the 1.8L displacement works with the 2.15:1 gear ratio to turn a prop with authority—great for maintaining speed without constantly chasing the throttle.
This F115LB is also ready for the marine environment. It’s salt water capable and uses water (open loop) cooling to manage temperature under long runs. You’ll also get peace-of-mind safeguards like a visual/audible engine alert system plus emergency RPM reduction to help protect the powerhead if something needs attention. For rigging and control, it’s set up with remote steering control and a power trim system so you can dial in your running angle as conditions change.
Practical bonus: a 35-amp alternator supports onboard electronics, and at 377 lbs dry (20-inch shaft), it’s a balanced choice for boats that want strong performance without unnecessary weight.
