2027 Yamaha XTO Offshore V8 5.6L XF450ESA

Bring serious offshore attitude to your transom with this Yamaha XTO Offshore XF450ESA—a standalone new outboard marine engine finished in classic Yamaha Gray. This is Yamaha’s big‑block answer for boats that live for wide horizons: a 5.6L V8 Fourstroke built to push heavy, high‑deadrise hulls and big center consoles with the kind of effortless muscle that makes long runs feel easy.
At the heart of it is 450 bhp (335.8 kW) at 6000 RPM, delivered by an 8‑cylinder, 32‑valve DOHC layout (4 valves per cylinder) with a 12.3:1 compression ratio. Translation: crisp throttle response and strong torque for getting larger offshore hulls on plane without drama—especially when you’re carrying fuel, crew, ice, and gear. The wide open throttle operating window of 5000–6000 RPM is tuned for real‑world offshore performance, while the 1.79:1 gear ratio helps convert that power into authoritative prop bite where it counts.
For long days on the water, this outboard is designed to be both capable and confidence‑inspiring. It’s water‑cooled (open loop), salt‑water capable, and equipped with a visual/audible engine alert system plus emergency RPM reduction—smart safeguards when conditions turn sporty or when you’re running far from the inlet. Starting is simple with an electric starter, and fueling is handled by fuel injection (gas, mid‑grade requirement), aimed at clean, consistent performance and strong cruise efficiency for the miles‑eating runs offshore anglers demand.
Rigging for the right application matters, and this model is set up with a 35-inch shaft and remote steering control, ideal for larger offshore transoms and bracket setups. You also get power trim for dialing in running attitude as seas and load change, and it’s counter‑rotating capable—a major plus for multi‑engine installations where balance and handling are everything. With a 102‑amp alternator, you’ve got charging power ready to support today’s onboard electronics.
If you’re looking to repower or build an offshore‑ready package around proven V8 four‑stroke strength, this Yamaha Gray XTO Offshore is ready to be the heartbeat of the next hull you rig. Warranty coverage applies per Yamaha’s current new‑engine program—contact us for the details for your intended use and registration.
