2027 Yamaha Four Stroke V6 Offshore F300ESB

Meet the 2027 Yamaha Four Stroke V6 Offshore F300ESB in classic Yamaha Gray—a serious, salt-water-capable outboard built for owners who want big-water confidence without giving up refined manners at the dock.
At the heart of this standalone engine listing is Yamaha’s 4.2L (4169cc) V6 architecture: a 24-valve DOHC design (4 valves per cylinder) with a perfectly square 96mm bore x 96mm stroke and a 10.3:1 compression ratio. Translation for the water: strong, usable torque that helps heavier offshore hulls and multi-engine setups jump on plane cleanly and stay there with less strain. Rated at 300 bhp (223.9 kW) at 5500 RPM, and designed to run in a 5000–6000 RPM full-throttle range, the F300ESB is a natural match for the kinds of deep-V offshore boats, large center consoles, and big bay boats that need muscle to carry fuel, gear, and crew—then still have punch left for the run home.
Because it’s a four-stroke with fuel injection, this outboard is tuned for smooth, predictable power delivery and efficient operation at cruise. That matters on long runs: steady midrange performance helps you settle into an economical cruising rhythm while maintaining the authority to adjust speed for sea conditions or to overtake chop without constantly “hunting” on the throttle.
Offshore practicality is baked in. Water (open loop) cooling supports consistent operating temps, and the engine is explicitly salt water capable for real coastal use. You also get the confidence of a visual/audible engine alert system plus emergency RPM reduction—extra safeguards designed to help protect the engine when conditions (or surprises) demand attention.
Rigging-friendly details round it out: an electric starter, 70-amp alternator for strong charging support, power trim, steering assist, and remote outboard steering control. Power is delivered through a propeller with a 1.75:1 gear ratio. This is the 35-inch shaft version, with a listed dry weight of 588 lbs (265 kg)—ideal for offshore transoms and bracket setups that call for this extra-long configuration.
The F300ESB runs on mid-grade gasoline, keeping ownership straightforward. Ask us about warranty coverage details and registration specifics available with this new Yamaha outboard—then let’s get this Yamaha Gray V6 hung on the hull that deserves it.
