2027 Yamaha Four Stroke Midrange 1.8L LF115XB
Description
Meet the 2027 Yamaha Four Stroke Midrange 1.8L LF115XB—an engine-only upgrade that brings big-boat confidence to the sweet-spot of everyday boating. Finished in classic Yamaha Gray, this midrange Fourstroke outboard is built to look right at home on everything from family pontoons and center consoles to aluminum fishing rigs and bay boats that want strong push without going oversized.
At the heart of this F115 is a 1.8L (1832cc) in-line 4-cylinder, DOHC, 16-valve design that delivers 115 bhp (85.8 kW) at 5500 RPM. That combination is a recipe for the kind of torque you feel when you’re climbing onto plane with a full crew, a livewell working, or a deck loaded for the weekend. The 2.15:1 gear ratio helps translate that power into authoritative thrust through a propeller—especially useful for boats that need quick response in chop, current, or when pulling away from the dock.
Because it’s fuel injected and runs on regular gas, the LF115XB is set up for easy ownership and efficient cruising. Settle into the midrange and you’ll appreciate how this four-stroke platform is designed to sip rather than guzzle while still keeping plenty in reserve for passing, towing, or punching through wind and wake.
This model is a 25-inch shaft outboard with power trim, designed for remote steering control applications—ideal for repowers or new rigging where clean helm integration matters. At 386 lbs dry, it’s a solid, confidence-inspiring match for boats that need midrange muscle without jumping to a heavier class.
For peace of mind on the water, Yamaha’s built-in protections include a visual/audible engine alert system plus emergency RPM reduction. And if your weekends include brackish bays or coastal runs, you’ll be glad it’s salt water capable and water-cooled (open loop).
If you’re looking for a fun, capable, midrange outboard that’s ready to turn hull potential into real-world performance, the Yamaha Gray LF115XB is ready to bolt on and go. Warranty coverage varies by program—ask us for current Yamaha warranty details on this new engine.
