2027 Yamaha Four Stroke V6 Offshore F250USB4

Rig your next offshore build with a true workhorse: this 2027 Yamaha Four Stroke V6 Offshore F250USB4—a standalone engine-only listing built for serious saltwater duty. Finished in Yamaha Classic White, it looks right at home on modern offshore center consoles, bay boats, and larger deep-V hulls that thrive on clean, confident power and long, efficient runs.
At the heart of this outboard is Yamaha’s 4.2L (4169 cc) DOHC V6 architecture with 24 valves (4 per cylinder) and electronic fuel injection. The result is a strong, responsive powerband that delivers 250 bhp (186.6 kW) at 5500 RPM, right where many offshore-friendly hulls like to live when you’re pushing into a chop or carrying a heavy load of crew and gear. With a 1.75:1 gear ratio turning a propeller, it’s tuned to translate that horsepower into the kind of usable thrust you feel when the boat climbs on plane and settles into an easy cruise.
Because it’s a modern four-stroke that runs on regular gasoline, this F250 is built to make long days more enjoyable—less time worrying about fuel stops and more time running the coastline. The water (open loop) cooling system is designed for marine operation, and it’s explicitly salt water capable, making it a smart match for anglers and families who boat where the water is hard on equipment.
This model’s 30-inch shaft is ideal for many offshore transoms, and the power trim helps you dial in the running attitude as conditions change. You’ll also appreciate the integrated safeguards: a visual/audible engine alert system plus emergency RPM reduction to help protect the engine if something needs your attention. Starting is simple with electric start, and with a 70-amp alternator, it’s ready to support the onboard electrical demands that come with real-world boating.
If you’re building or repowering for offshore confidence—strong V6 torque, efficient four-stroke manners, and Yamaha engineering in Classic White—this F250USB4 is ready to hang on the transom. Ask us about warranty coverage details available for this new engine.
