2027 Yamaha Four Stroke V6 Offshore LF250USB
Description
Rig serious offshore capability with this 2027 Yamaha Fourstroke V6 Offshore LF250USB—a standalone outboard built to be the muscle behind today’s bigger, heavier center consoles, bay boats, and offshore fishing hulls that want strong midrange pull without stepping up to a much heavier powerplant. Finished in Yamaha Gray, it looks right at home on modern transoms and pairs cleanly with just about any hull color scheme.
At the heart of this V6 is 4.2L (4169cc) of displacement, six cylinders, and 24 DOHC valves (4 per cylinder)—a combination designed to breathe efficiently and deliver the kind of torque that pops a loaded boat onto plane and keeps it there when the sea state isn’t cooperating. With 250 bhp (186.6 kW) at 5500 RPM and a full-throttle range of 5000–6000 RPM, the LF250USB is tuned for real-world offshore running: strong acceleration out of the hole, confident cruise, and the ability to hold speed when the boat’s carrying passengers, fuel, ice, and gear.
Because it’s a 4-stroke running fuel injection, you get crisp throttle response and the ability to run regular gas, helping keep operating costs reasonable—especially for owners who rack up hours. The 1.75:1 gear ratio and propeller drive are a proven match for pushing offshore-capable hulls efficiently, and the power trim makes it easy to dial in the running attitude for fuel economy at cruise and comfort as conditions change.
This engine is built for the salt: it’s salt water capable and uses water (open loop) cooling. You’ll also appreciate the smart protections built in, including a visual/audible alert system and emergency RPM reduction designed to help you respond quickly if something needs attention. Starting is simple with electric start, and a stout 70-amp alternator supports onboard electronics demands.
The LF250USB comes in a 30-inch shaft configuration and weighs 562 lbs (254 kg) dry—ideal for applications needing an extra-long shaft. It’s also counter-rotating capable, includes steering assist, and is set up for remote steering control, making it a great fit for single or multi-engine offshore rigs.
