2027 Yamaha Four Stroke V6 Offshore F300ECB
Description
Bring serious offshore confidence to your transom with this 2027 Yamaha Four Stroke V6 Offshore F300ECB—a new, engine-only listing built for boaters who want big-water muscle without the bulk of a larger block. Finished in Yamaha Gray, it looks as sharp as it runs, and it’s ready to be the heartbeat of your next repower or new build.
At 300 bhp (223.9 kW) @ 5500 RPM, this 4.2L (4169 cc) V6 is right in the sweet spot for offshore-capable center consoles and deep‑V hulls that need strong midrange punch to climb on plane quickly, carry crew and gear, and stay composed when conditions get sporty. The DOHC, 24‑valve layout (four valves per cylinder) helps it breathe efficiently across the rev range, delivering the kind of torque you feel when you push the throttles forward and the bow settles into a clean, confident run.
For long days on the water, fuel economy at cruise matters. This Yamaha four-stroke is fuel injected and designed to run on mid‑grade gas, helping provide smooth, consistent performance for the run to the grounds and back. Cooling is handled by a water (open loop) system, and it’s salt water capable, making it a natural fit for coastal and offshore duty.
Rigging-wise, the 35-inch shaft makes this F300ECB a strong match for modern offshore transoms, and it’s set up for remote steering control with power trim for dialing in attitude as load and sea state change. A 70‑amp alternator supports onboard electronics demands, and the built-in visual/audible alert system plus emergency RPM reduction add extra peace of mind when you’re running far from the dock. Power is delivered through a propeller with a 1.75:1 gear ratio, balancing acceleration and top-end potential.
Dry weight is 588 lbs (265 kg)—substantial enough to feel planted offshore, while still well-suited to the hull classes that commonly pair with a 300.
Ask your dealer for current Yamaha warranty coverage details on this new engine, and let’s get this Yamaha Gray V6 ready to power your next offshore season.
