2027 Yamaha Four Stroke Midrange 1.8L F115XB
Description
Meet the 2027 Yamaha Four Stroke Midrange 1.8L F115XB—finished in classic Yamaha Gray and ready to be the “just-right” powerplant for a wide range of real-world hulls. This is an engine-only listing (not a complete boat), ideal for repowers or fresh builds where you want strong, dependable performance without moving into oversized, over-thirsty territory.
At 115 bhp (85.8 kW) turning up to 5500 RPM, this midrange in-line 4 delivers the kind of punch that makes 17–20ish foot center consoles, bay boats, aluminum fishing rigs, and light pontoons feel lively—especially when you’re loaded with gear and passengers. The 1.8L (1832 cc) displacement and DOHC 16-valve layout help it breathe efficiently, giving you confident acceleration onto plane and solid midrange pull for staying on step in chop or current.
Because it’s fuel injected and runs on regular gas, the F115XB is built for easy ownership and practical day-to-day operation. Dial in a comfortable cruise and you’ll appreciate how smoothly it carries speed—great for long runs to the bite, hopping between sandbars, or stretching your fuel budget on family days. The 2.15:1 gear ratio is a smart match for prop-driven setups, helping translate power into usable thrust, and power trim makes it easy to fine-tune attitude for efficiency and ride comfort as conditions change.
This Yamaha is also set up for the marine world you actually live in. It’s salt-water capable, uses water (open loop) cooling, and includes a visual/audible alert system with emergency RPM reduction—added peace of mind when you’re far from the ramp. The electric starter keeps things simple at launch, and the 35-amp alternator supports onboard electronics so you can run your essentials with confidence.
Rigging note: this model is a 25-inch shaft and is designed for remote steering control, making it a great fit for many offshore-leaning transoms and modern console layouts. With a dry weight of 386 lbs (175 kg), it hits a sweet spot of capability and balance for boats that want strong performance without excessive stern weight.
Stop by and see how this Yamaha Gray F115XB can transform your transom into an efficient, responsive, ready-for-anything setup. Warranty coverage varies by program—ask us for the current Yamaha warranty details available with this engine.
