2027 Yamaha XTO Offshore V8 5.6L LXF450XSA4
Description
Meet the Yamaha XTO Offshore V8 5.6L (LXF450XSA4) in Yamaha Classic White—a standalone, engine-only powerhouse built for big-water confidence and serious offshore attitude. This is a new outboard, ready to be the heart of your next build or repower.
At the center is Yamaha’s 5.6L V8 Fourstroke architecture: 8 cylinders, 32 valves, and DOHC breathing (4 valves per cylinder) paired with a perfectly square 96 mm x 96 mm bore and stroke. The result is the kind of muscle you want when you’re pushing the hulls that *demand* it—think heavier, offshore-capable center consoles and large multi-engine applications where instant authority matters. With 450 bhp (335.8 kW) at 6000 RPM and a full-throttle range of 5000–6000 RPM, this XTO is tuned to deliver strong pull through the working band, making it a natural match for boats that need to climb on plane decisively, carry load without drama, and hold speed when conditions get lumpy.
Because offshore days are measured in miles, not minutes, efficiency at cruise matters. This XTO’s fuel-injected gas setup (running mid-grade fuel) is designed to keep throttle response crisp and fueling precise—exactly what you want when you’re settling into a long run at cruise and looking for strong range without sacrificing the ability to punch it when the sea state or schedule changes.
It’s also built for the environment it lives in. The XTO is salt water capable, uses water (open loop) cooling, and includes an engine alert system (visual/audible) plus emergency RPM reduction—extra reassurance when you’re far from the inlet and want the engine to help look after itself.
Rigging-wise, this model is a 25-inch shaft outboard with remote steering control, power trim, and propeller propulsion. The 1.79:1 gear ratio helps translate power into real-world thrust, and it’s counter-rotating capable, making it especially attractive for twin, triple, or quad setups where you want clean handling characteristics. Electrical demand on modern boats is no joke, and the 102-amp alternator is ready to support today’s onboard loads.
Dry weight is 963 lbs (437 kg)—substantial, because serious offshore capability is. If you’re chasing big-water performance in a refined Yamaha Classic White finish, this XTO Offshore is ready to power the mission. Warranty coverage applies per Yamaha’s new-engine warranty policy—ask us for the current details and registration specifics.
