2027 Yamaha XTO Offshore V8 5.6L XF450XSA
Description
Meet the 2027 Yamaha XTO Offshore V8 5.6L XF450XSA—a standalone, engine-only powerhouse built for serious offshore rigs that live for heavy loads, long runs, and rough-water confidence. Finished in classic Yamaha Gray, it looks every bit as purposeful as it performs.
At the heart of this XTO Offshore outboard is a 5.6L V8 Fourstroke with 8 cylinders, 32 valves, and DOHC breathing—engineering that’s all about delivering strong, usable muscle where offshore hulls need it most. With 450 bhp (335.8 kW) at 6000 RPM and a full-throttle range of 5000–6000 RPM, this is the kind of output that pairs naturally with large center consoles, big bay boats, and multi-engine offshore setups that demand authority coming out of the hole and composure when the seas stand up.
Because it’s fuel injected and designed as a modern 4-stroke, it’s tuned for efficient, steady cruising—not just headline horsepower. Run it in the midrange and you get the kind of smooth, confident power delivery that makes long days on the water feel easy, with mid-grade gas keeping the requirements straightforward for real-world use.
Offshore practicality is baked in. Water (open loop) cooling supports the mission, and it’s explicitly salt water capable, ready for coastal life. The 102-amp alternator helps keep onboard systems supported, and the visual/audible engine alert system plus emergency RPM reduction add peace of mind when conditions (or distractions) get real.
Rigging-wise, this model is a 25-inch shaft outboard with remote steering control, power trim, and propeller propulsion backed by a 1.79:1 gear ratio—a setup aimed at pushing heavy hulls efficiently and holding bite when you’re loading the prop. Planning a twin or triple set? It’s also counter-rotating capable, giving builders and repower customers flexibility to dial in handling.
With a dry weight of 963 lbs (437 kg), it’s a serious engine for serious boats—exactly what you want when the goal is to turn big water into a smaller problem. If you’re hunting for flagship offshore power in Yamaha Gray, this XTO Offshore V8 is ready to be the centerpiece of your next build or repower.
