2027 Yamaha Four Stroke V6 Offshore F300XSB
Description
Meet the 2027 Yamaha Four Stroke V6 Offshore F300XSB—an engine-only listing built for boaters who want big-water confidence without the bulk. Finished in classic Yamaha Gray, this V6 Offshore outboard brings the kind of punch that feels right at home on today’s larger bay boats, offshore center consoles, and multi-engine hulls that like to run fast, run loaded, and run far.
At the heart of the F300XSB is Yamaha’s 4.2L (4169 cc) 6-cylinder platform with DOHC breathing and 24 valves (4 per cylinder). The result is strong, smooth power that comes on confidently when you’re pushing a heavy hull onto plane, carrying a full crew, or making a tight pass in slop. With 300 bhp (223.9 kW) at 5500 RPM and a full-throttle range of 5000–6000 RPM, it’s tuned for real-world offshore use—quick response when you need it, and the ability to settle into a comfortable cruise without feeling strained.
Fuel economy matters when the horizon is the plan, and this Yamaha’s fuel-injected setup and 10.3:1 compression are designed to deliver efficient, consistent performance on mid-grade gasoline. Pair that with water (open loop) cooling, and you’ve got a package built to keep operating temps in check while you rack up hours in coastal conditions.
This is a 25-inch shaft model, a common fit for many offshore-capable transoms and brackets, and it’s purpose-built for saltwater duty (salt water capable: yes). The 1.75:1 gear ratio and propeller drive translate power into strong midrange authority—exactly what heavier hull classes appreciate when conditions get sporty.
Day-to-day usability is equally dialed in: electric start, power trim, remote steering control with steering assist, and a 50-amp alternator to help support onboard electronics. Yamaha also builds in peace of mind with a visual/audible engine alert system and emergency RPM reduction to help protect your investment if something needs attention.
Ready to repower or rig a new build? The Yamaha Gray F300XSB brings offshore-ready muscle in a refined, modern package—built to make long runs feel shorter and rough water feel a little less serious. For warranty coverage details and eligibility, contact the dealer directly.
