2027 Yamaha Four Stroke V6 Offshore LF300UCB
Description
Meet the 2027 Yamaha Four Stroke V6 Offshore LF300UCB—an engine-only listing built for big-water confidence and serious everyday usability. Finished in Yamaha Gray, this V6 Offshore outboard looks right at home on modern offshore rigs, and it’s sized and spec’d to be a sweet spot for boats that need strong midrange shove without jumping into heavier, thirstier powerplants.
At the heart of this 4.2L (4169 cc) V6 is Yamaha’s Fourstroke design with DOHC cylinder heads and 24 valves (4 per cylinder). The result is the kind of smooth, quick-revving power that makes a difference when you’re pushing a heavy bay boat, offshore center console, or multi-engine hull onto plane and keeping it there. With 300 bhp (223.9 kW) at 5500 RPM and a full-throttle range of 5000–6000 RPM, it’s engineered to deliver strong acceleration and a confident cruise—ideal for hulls that want to run efficiently in the midrange but still have muscle in reserve when the weather turns or the inlet stacks up.
Fueling is fuel injected gasoline (with mid-grade requirements), helping provide crisp throttle response and consistent performance. And with water (open loop) cooling, it’s built with the marine environment in mind. This model is also salt water capable, making it a natural fit for coastal use where reliability and corrosion-minded design matter every trip.
For rigging and control, the LF300UCB is set up with remote steering control, power trim, and a propeller drive with a 1.75:1 gear ratio—a combination that supports efficient prop selection and strong low-to-midrange pull for the hull class it’s meant to power. The 30-inch shaft configuration is ready for offshore transoms that demand extra height, and at a dry weight of 562 lbs (254 kg), it delivers serious offshore power in a package many multi-engine applications can plan around.
On the peace-of-mind side, Yamaha includes an engine alert system (visual/audible) plus emergency RPM reduction to help protect your investment if an issue is detected.
If you’re shopping for a modern offshore outboard that balances punchy V6 performance with practical cruise efficiency and smart engine protection—this Yamaha Gray LF300UCB is ready to be the heartbeat of your next repower or build. Warranty coverage varies by program and sale terms—contact us to confirm what applies to this specific engine.
