2027 Yamaha Four Stroke V6 Offshore LF300USB
Description
Meet the 2027 Yamaha Four Stroke V6 Offshore LF300USB—an engine-only listing built to be the muscle and manners behind serious offshore-capable hulls. Finished in classic Yamaha Gray, this V6 outboard looks right at home on the transom of larger center consoles, bay boats, and offshore fishing platforms that demand confident power without giving up day-long comfort at the helm.
At the heart of this Yamaha F300 is a 4.2L (4169cc) 6-cylinder, 24-valve DOHC V6 that’s all about strong, usable thrust. With 300 bhp (223.9 kW) at 5500 RPM and a full-throttle range of 5000–6000 RPM, it’s tuned for the kind of midrange punch that helps heavier offshore hulls climb on plane cleanly, carry crew and gear without drama, and stay composed when conditions get sporty. The 1.75:1 gear ratio helps translate that power into practical propulsive bite, making it a great match for boats that need authority out of the hole and steady pull through changing seas.
Because it’s a modern fuel-injected four-stroke, you get the crisp response you want at the dock and the kind of efficient, relaxed operation boaters appreciate when settling into a cruise and watching the fuel plan for the day. It runs on mid-grade gas, and the 70-amp alternator supports the electrical demands that tend to come with offshore days.
This LF300USB is built for the environment it’s named for: it’s salt-water capable, cooled by water (open loop), and backed up by Yamaha’s visual/audible alert system plus emergency RPM reduction for extra peace of mind. The power trim makes it easy to dial in running attitude, and steering assist with remote outboard steering control helps reduce fatigue on long runs.
Rigging-wise, this model is a dedicated 30-inch shaft setup and carries a dry weight of 562 lbs, making it a strong candidate for offshore transoms designed around long-shaft power. It’s also counter-rotating capable, a big plus if you’re planning a twin-engine installation.
