2027 Yamaha XTO Offshore V8 5.6L XF450XSA4
Description
Meet the Yamaha XTO Offshore V8 5.6L XF450XSA4—a new, engine-only listing built for boaters who want serious offshore push without the drama. Finished in Yamaha Classic White, this XTO looks right at home on today’s big-water center consoles, bay-to-bluewater hybrids, and other heavy, high-freeboard hulls that demand real muscle to lift, hold plane, and run confidently when the conditions turn lumpy.
At the heart of it is a 5.6L, 32-valve DOHC V8 Fourstroke that delivers 450 bhp (335.8 kW) at 6000 RPM, with a full-throttle range of 5000–6000 RPM. Translation: strong, useable power where offshore boats live—perfect for pushing substantial hulls, multi-engine setups, and loaded-down fishing days. The 1.79:1 gear ratio helps convert that power into prop authority, giving you the kind of bite that matters when you’re climbing onto plane or holding speed in a head sea.
This outboard is fuel injected and runs on mid-grade gasoline, designed for smooth throttle response and consistent performance. And because long days offshore are won at cruise, not at wide-open throttle, the big-displacement V8 platform is well-suited to delivering relaxed, efficient cruising power—exactly what you want when you’re covering miles and managing fuel stops.
Built for the harsh stuff, it’s salt-water capable and uses water (open loop) cooling. You’ll also appreciate the built-in visual/audible engine alert system plus emergency RPM reduction—extra peace of mind when you’re far from the inlet. Starting is simple with an electric starter, and the 102-amp alternator supports the kind of onboard electronics load offshore boats are known for.
This model features a 25-inch shaft and power trim, with remote steering control and propeller propulsion. It’s also counter-rotating capable, making it an excellent match for twin or triple installations.
Dry weight is 963 lbs, so it’s a serious engine for serious hulls—and a standout choice when your priority is offshore-grade thrust, control, and confidence. Warranty coverage varies by program and region—ask us for the current Yamaha warranty details on this new XTO.
