2027 Yamaha Four Stroke V6 Offshore LF250USB4

Description

Meet the 2027 Yamaha Four Stroke V6 Offshore LF250USB4—an engine-only listing built for serious saltwater miles, not a complete boat. Finished in Yamaha Classic White, this 30-inch-shaft offshore outboard brings a clean, purposeful look to brackets and tall transoms while delivering the kind of punch that makes heavy hulls feel lighter.
At the heart of this Yamaha F250 is a 4.2L (4169cc) V6 four-stroke with 24 valves and DOHC breathing—six cylinders working together to produce 250 bhp (186.6 kW) at 5500 RPM. That’s the sweet spot for many offshore-capable center consoles, walkarounds, and larger bay boats that need strong midrange torque to climb onto plane without drama, then hold a confident cruise when the chop builds. With a wide-open throttle range of 5000–6000 RPM and a 1.75:1 gear ratio turning a propeller setup, it’s tuned to push real hull weight efficiently and keep you in the powerband when seas and load change.
Because this is a modern fuel-injected four-stroke designed to run on regular gas, it’s a practical choice for long days and longer runs—especially where predictable fuel economy at cruise matters most. Open-loop water cooling is built for the marine environment, and yes, it’s salt-water capable, making it a natural fit for coastal duty.
On the confidence and convenience side, this outboard comes with electric start, a 70-amp alternator to support onboard electrical demands, and a power trim system to dial in running angle for changing conditions. Remote outboard steering control is supported, along with steering assist system capability for a more controlled feel at the helm. For peace of mind, Yamaha’s visual/audible engine alert system and emergency RPM reduction are onboard to help protect your investment when conditions—or attention—get tested.
Need multi-engine flexibility? This model is counter-rotating capable, a big plus for twin or triple setups looking for balanced handling and tracking. Dry weight is 562 lbs (254 kg) in this 30-inch configuration—substantial, offshore-ready hardware designed to work.
