2027 Yamaha XTO Offshore V8 5.6L XF450USA4

Meet the muscle behind your next big-water build: the 2027 Yamaha XTO Offshore V8 5.6L XF450USA4 outboard in Yamaha Classic White. This is an engine-only listing—perfect for repower projects or new rigging plans where you want serious offshore thrust without shopping an entire boat.
At 450 bhp (335.8 kW) turning up to 6000 RPM, this 5.6L, 32-valve DOHC V8 is built for the kinds of hulls that demand authority—large center consoles, offshore-capable walkarounds, and other heavy, high-freeboard platforms that need strong torque to climb on plane confidently and stay composed in chop. The square 96 mm x 96 mm bore and stroke and 12.3:1 compression ratio point to an engine designed to pull hard through the midrange while still stretching its legs in the 5000–6000 RPM full-throttle band.
Cruising efficiency matters offshore, and this XTO’s fuel-injected, mid-grade-gas setup is tuned for clean, consistent delivery—helping you hold a steady cruise without the “hunting” you can feel in lesser setups when seas and load change. Pair that with water (open loop) cooling and you’ve got a package ready for long days of running, trolling, and hopping between spots.
Rigging-friendly details make it an excellent candidate for multi-engine transoms too. With a 1.79:1 gear ratio swinging a propeller, plus power trim and remote steering control, it’s set up for dialed-in attitude control and precise response. Counter-rotating capability also gives you flexibility when planning twins, triples, or quads—helping balance torque and improve handling when the conditions turn sporty.
Offshore confidence is also about protection and uptime: it’s salt-water capable and includes a visual/audible engine alert system with emergency RPM reduction to help you respond quickly if something isn’t right. Starting is simple with an electric starter, and onboard electrical support is robust thanks to a 102-amp alternator—great for modern electronics loads.
This model wears its Yamaha Classic White finish like it belongs on a serious transom—clean, timeless, and ready to match a wide range of hull colors and rigging styles.
