2027 Yamaha Four Stroke V6 Offshore F250USB
Description
Bring serious offshore muscle to your transom with this 2027 Yamaha Four Stroke V6 Offshore F250USB—a standalone outboard built for crews who run big water and want confident, repeatable performance. Finished in classic Yamaha Gray, it looks right at home on modern offshore rigs while staying purpose-built where it counts: the powerhead, midsection, and gearcase doing the hard work mile after mile.
At the heart of this 4.2L (4169cc) V6 is a 24-valve DOHC layout (4 valves per cylinder) with a 10.3:1 compression ratio and fuel injection, delivering a stout 250 bhp (186.6 kW) at 5500 RPM. That output is the sweet spot for many offshore-capable hulls that want strong midrange pull for heavier loads—think full fuel, coolers, crew, and gear—without feeling like you’re constantly asking the engine for “just a little more.” With a 1.75:1 gear ratio turning a propeller, the setup is tuned for the kind of push that helps bigger center consoles, dual consoles, and offshore fishing platforms climb on plane and stay there with authority.
Because it’s a four-stroke that runs on regular gas, this F250 is also a smart pick for long days at cruise, when efficiency matters as much as speed. Yamaha’s offshore focus shows up in the details that keep you informed and protected: a visual/audible engine alert system plus emergency RPM reduction help you stay ahead of issues before they become trip-enders.
This is a salt-water capable package with open-loop water cooling, an electric starter, and a robust 70-amp alternator to help support today’s onboard electronics. It’s configured with a 30-inch shaft and a dry weight of 562 lbs, ideal for bracketed boats and many offshore transoms that call for extra shaft length. You also get power trim, steering assist, and remote outboard steering control, making it a great match for comfortable helm operation on longer runs.
Looking to repower or spec a new build? This Yamaha Gray F250USB brings offshore-ready torque, strong horsepower, and the kind of everyday usability that makes miles feel easier. Ask us about warranty coverage available with this new engine.
