2027 Yamaha XTO Offshore V8 5.6L XF450ESA2

Meet the Yamaha XTO Offshore V8 5.6L XF450ESA2—a standalone new outboard marine engine built for captains who measure weekends in offshore miles, not marina minutes. Finished in classic Yamaha White, this XTO looks right at home hanging off the back of serious, open-water hulls—and it’s engineered to back up that look with real push.
At the heart of it is a 5.6L, 4-stroke V8 with 8 cylinders and 32 DOHC valves (4 per cylinder), spinning up to a 6000 RPM peak and delivering a bold 450 bhp (335.8 kW). That combination is exactly what you want for the kinds of heavier offshore center consoles, large bay boats, and deep‑V platforms that need strong acceleration onto plane, confident midrange pull in rolling seas, and the authority to keep pace when the water (and the schedule) gets demanding. With a 1.79:1 gear ratio, this outboard is tuned to turn a prop with the kind of grip and thrust that matters when you’re loaded with fuel, gear, and crew.
Long runs are where the XTO name earns its keep. This engine’s fuel-injected setup and 12.3:1 compression ratio are designed to keep power responsive and efficient, and it’s rated for mid‑grade gasoline. Cruise is where most offshore hours live, and the XTO’s big-displacement V8 character is all about moving substantial hulls with less strain—translating to strong real‑world economy at steady speeds.
Offshore confidence isn’t just horsepower—it’s protection. This model is salt water capable, uses water (open loop) cooling, and includes a visual/audible engine alert system plus emergency RPM reduction to help safeguard the powerplant when conditions—or an unexpected issue—try to ruin the day.
Rigging-ready details round it out: electric start, 102-amp alternator for robust charging on electronics-heavy boats, power trim, remote steering control, and counter-rotating capability for multi‑engine setups. It’s a 35-inch shaft offshore configuration, with a listed dry weight of 1010 lbs (458 kg).
Want white‑hot offshore performance in a clean Yamaha White package? This XTO Offshore V8 is ready to be the muscle behind your next build. Warranty coverage may apply—ask our team for the details available on this engine.
