2027 Yamaha XTO Offshore V8 5.6L XF450XSA2

Meet the Yamaha White 2027 Yamaha XTO Offshore V8 5.6L XF450XSA2—a new, engine-only powerhouse built for serious offshore work. This is a standalone XTO Offshore outboard (not a complete boat), designed to be the heart of a big-water setup where heavy hulls, loaded fuel tanks, and long runs are part of the plan.
At the center is a 5.6L V8 four-stroke making 450 bhp (335.8 kW) at 6000 RPM, with a 5000–6000 RPM full-throttle range. That kind of output is tailor-made for larger offshore center consoles, big bay boats, and other substantial hull classes that demand strong acceleration onto plane and confident pull when you’re carrying a crew, gear, and ice. The 1.79:1 gear ratio helps translate that power to the prop with the authority you want when the sea state turns sporty.
This V8 is built with refinement and durability in mind: 32 valves with DOHC (4 valves per cylinder), a 12.3:1 compression ratio, and fuel injection for crisp response and dependable starting via electric start. For long-distance cruising, the efficient four-stroke design and modern fueling help you settle into an easy-running rhythm—great for stretching a day’s range without living at the fuel dock (uses mid-grade gas).
Offshore days can be unpredictable, so Yamaha backs the experience with smart safeguards: a visual/audible engine alert system plus emergency RPM reduction to help protect the engine if conditions demand it. It’s also explicitly salt-water capable, and cooling is handled by water (open loop)—exactly what you want for real coastal and offshore use.
Rigging-wise, this model features a 30-inch shaft and remote steering control, with power trim to help dial in running attitude as conditions change. Need to build a multi-engine setup? It’s counter-rotating capable, giving you flexibility for balanced handling and control.
With a robust 102-amp alternator and a dry weight of 988 lbs, the XTO Offshore is the kind of Yamaha White flagship outboard chosen when the mission is simple: go farther, run harder, and come home confident. Warranty coverage applies per manufacturer policy—contact us for current details and registration specifics.
