2027 Yamaha Four Stroke V6 Offshore F300UCB2

Description

Meet the 2027 Yamaha Four Stroke V6 Offshore F300UCB2—a new, engine-only listing built for the kind of offshore days that start early, run far, and end with a long ride home. Finished in Yamaha Pearl White, this outboard looks right at home on modern center consoles and offshore-capable fishing hulls where a clean transom matters almost as much as performance.
At the heart of this Yamaha F300 is a 4.2L (4169 cc) DOHC V6 with 24 valves (4 per cylinder), designed to deliver strong, confident power where it counts. With 300 bhp (223.9 kW) at 5500 RPM and a full-throttle range of 5000–6000 RPM, it’s a natural match for offshore hulls that need authoritative acceleration onto plane, plenty of midrange pull for loaded runs, and the muscle to keep speed in reserve when seas build. The 1.75:1 gear ratio helps translate that power into effective prop-driven bite, making it a solid choice for heavier, offshore-oriented setups that demand real thrust rather than just top-end talk.
Because this is a Fourstroke and fuel injected, it’s tuned for the kind of smooth, predictable response you want when you’re dialing in cruise and covering water. Pair that with water (open loop) cooling, electric start, and power trim, and you’ve got an outboard that’s ready for long days of frequent speed changes—slow trolling, quick hops, and steady cruising—without feeling fussy.
Offshore confidence isn’t only about horsepower. This F300UCB2 is salt water capable and includes an engine alert system (visual/audible) plus emergency RPM reduction, giving you extra peace of mind when your plans include open water and longer runs.
Practical rigging notes matter, too: this model comes in a 30-inch shaft configuration and uses remote steering control, making it a strong fit for offshore transoms and bracket setups designed around that extra length. It carries a listed dry weight of 562 lbs (254 kg).
If you’re looking to power an offshore-ready hull with a clean-looking Pearl White Yamaha and a proven 300-horse V6 platform, this standalone engine deserves a serious look. Ask us about warranty coverage available for this new engine.
