Description

Meet the 2027 Yamaha XTO Offshore V8 5.6L (LXF450USA4) — a new, engine-only outboard built for big-water confidence and big-hull authority. Finished in Yamaha Classic White, it looks as clean and purposeful on the bracket as it feels when you roll into the throttle.
At the heart of this XTO Offshore is a 5.6L, 32‑valve DOHC V8 four-stroke that delivers 450 bhp (335.8 kW) at 6000 RPM. That combination of displacement and high-output breathing is exactly what you want when you’re powering offshore-capable hulls that need strong, immediate push to lift on plane, carry load, and hold speed in changing conditions. The 1.79:1 gear ratio is tuned for prop-driven authority, translating the V8’s muscle into the kind of grip that helps heavier center consoles, large dual consoles, and wide-beam offshore platforms feel composed when it counts.
This is a modern, fuel-injected setup designed for real-world cruising: responsive power delivery for dialing in an efficient cruise band, with mid-grade gasoline as the requirement. Cooling is handled by water (open loop), and it’s built to be salt-water capable, making it a strong candidate for coastal and offshore duty where long runs and tough environments are the norm.
Day-to-day operation is made easier with an electric starter, power trim, and remote steering control, while a visual/audible engine alert system and emergency RPM reduction add confidence when conditions get demanding. Need rigging flexibility for multi-engine applications? This model is counter-rotating capable, helping match prop rotation to your setup.
With a 30-inch shaft and a dry weight of 988 lbs (448 kg), the XTO Offshore is purpose-built for substantial transoms and brackets—exactly where a 450-class offshore outboard belongs. It also carries a robust onboard electrical foundation with a 102-amp alternator, supporting the real electrical loads that offshore boats tend to bring.
This listing is for the engine only (not a complete boat). Ask us about current warranty coverage available for new Yamaha outboards and rigging requirements for your specific application.
