2027 Yamaha XTO Offshore V8 5.6L XF450USA

Meet the 2027 Yamaha XTO Offshore V8 5.6L XF450USA—a stand‑alone, engine‑only listing built for the kind of offshore days that start before sunrise and end when the fish box (or the horizon) says so. Finished in Yamaha Gray, this XTO Offshore outboard looks every bit as serious as it runs, with the clean, purposeful presence you want hanging on the transom of a modern big-water rig.
At the heart of it is Yamaha’s 5.6L V8 Fourstroke, pushing out 450 bhp (335.8 kW) at 6000 RPM. That kind of output isn’t just about a big top number—it’s about the punch you feel when a heavy hull needs to climb on plane, when you’re loaded with crew and gear, or when you’re throttling up to keep control in stacked seas. With 8 cylinders, a DOHC layout, and 32 valves (4 per cylinder), this platform is designed to breathe and pull hard across the working range, with a full-throttle operating window of 5000–6000 RPM.
For owners who rack up real miles, cruise efficiency matters as much as bragging rights. This V8 uses fuel injection and runs on mid‑grade gasoline, delivering crisp response when you roll into the throttle and stable, predictable manners when you settle into that long offshore cruise. Cooling is water (open loop), and it’s salt water capable, making it a natural fit for coastal and bluewater use.
Rigging for serious boats is baked in. You’re getting a 30-inch shaft and remote steering control, paired with power trim and propeller drive with a 1.79:1 gear ratio—a setup well suited to larger offshore center consoles, walkarounds, and express-style hulls that demand authority and leverage at the prop. It’s also counter-rotating capable, a huge advantage for twin or triple installations looking for balanced handling and confident tracking.
Confidence features include a visual/audible alert system and emergency RPM reduction to help protect the engine when conditions demand attention. And with a stout 102-amp alternator, you have serious charging support for today’s electronics-heavy helm setups.
Ask us about warranty coverage available for this new Yamaha outboard, and let’s match this Yamaha Gray powerhouse to the hull class and mission you have in mind.
