2027 Yamaha XTO Offshore V8 5.6L XF450ESA4

$56,400

Description

Bring big-water muscle to your transom with this 2027 Yamaha XTO Offshore V8 5.6L XF450ESA4—a new, engine-only listing built for serious offshore duty. Finished in Yamaha Classic White, it looks as clean and purposeful as it runs, and it’s ready to be the heart of a high-horsepower repower or new build.
At 450 bhp (335.8 kW) and a 5.6L V8 spinning up to 6000 RPM (with a 5000–6000 RPM full-throttle range), this XTO Offshore is right at home pushing the kinds of hulls that demand real torque to lift, hold plane, and stay composed when the weather turns—think heavy, offshore-capable center consoles and large multi-engine applications where strong midrange pull matters as much as top-end charge. The square 96 mm bore x 96 mm stroke and 12.3:1 compression ratio are part of a package designed to deliver confident acceleration and sustained power when you’re loaded with fuel, gear, and crew.
Because long runs are what offshore power is made for, this Fourstroke’s fuel-injected, 4-stroke design helps you settle into an efficient cruise mindset—smooth, consistent power delivery without the “all-or-nothing” feel. Feed it mid grade gas, let the water (open loop) cooling do its job, and enjoy the kind of steady operation that makes covering miles feel easy.
This model is also built with offshore practicality in mind: salt water capable, a visual/audible alert system, and emergency RPM reduction for added peace of mind. An electric starter, 102-amp alternator, and remote steering control support modern rigging needs, while power trim helps you dial in the running attitude for changing sea states and loads. The 1.79:1 gear ratio and propeller drive are matched to the mission, and it’s counter-rotating capable for multi-engine setups.
It all comes in the rugged 35-inch shaft configuration, with a listed dry weight of 1010 lbs, ready to anchor a serious offshore propulsion package. Ask us about warranty coverage details for this new Yamaha outboard and how to spec it for your hull class and rigging plan.
