2027 Yamaha Four Stroke V6 Offshore F300USB

Meet the 2027 Yamaha Four Stroke V6 Offshore F300USB—an engine-only listing built for boaters who want big-water confidence without big-drama ownership. Finished in classic Yamaha Gray, this V6 Offshore outboard looks as sharp on the transom as it feels on the throttle.
At the heart of the F300USB is a 4.2L (4169 cc) DOHC 24-valve V6 that delivers 300 bhp (223.9 kW) at 5500 RPM—the kind of horsepower and torque curve that makes sense for offshore-capable hulls that like to run loaded: extra crew, full fuel, gear, and the kind of conditions where staying on plane matters. With a full-throttle range of 5000–6000 RPM and a 1.75:1 gear ratio, it’s designed to turn a prop with authority and keep your boat responsive when you need to accelerate onto plane or punch through chop.
Because it’s a modern four-stroke, fuel-injected setup, you’re getting the smooth, efficient character boaters love for long cruises—steady midrange performance with fuel economy that shines where you actually spend your time: at cruise. Add in a 70-amp alternator, and you’ve got the electrical muscle to support today’s onboard demands while you’re running.
This is a salt-water-capable outboard with water (open loop) cooling, plus a visual/audible alert system and emergency RPM reduction to help protect the engine when conditions—or sensors—say it’s time to back things down. The electric starter, power trim, steering assist system, and remote outboard steering control round out a package that’s made to feel refined at the helm, not tiring.
Built in a 30-inch shaft configuration and weighing 562 lbs dry (254 kg), the F300USB is a serious offshore-minded choice for compatible transoms that call for extra shaft length.
Ask our team about warranty coverage details and current Yamaha programs for this new engine, and let’s match this Yamaha Gray V6 Offshore powerplant to your hull and your kind of boating.
