2027 Yamaha Four Stroke V6 Offshore F300ESB4
Description
Bring serious offshore attitude to your repower or new build with this Yamaha Four Stroke V6 Offshore F300ESB4—a standalone 300 bhp (223.9 kW) outboard built for big-water miles and heavy hulls that demand real punch. Finished in Yamaha Classic White, it looks right at home on everything from modern center consoles to hard-working offshore fishing rigs.
At the heart of this 4.2L (4169 cc) V6 is a square 96 mm x 96 mm bore and stroke and a 10.3:1 compression ratio, designed to deliver the kind of confident, load-carrying torque you want when you’re pushing a full crew, fuel, ice, and gear. With 300 horsepower at 5500 RPM and a full-throttle operating range of 5000–6000 RPM, this is a strong match for offshore-capable hulls where quick planing, solid midrange pull, and predictable throttle response matter as much as top-end.
Because it’s a fuel-injected Yamaha Fourstroke with DOHC and 24 valves (4 per cylinder), you get crisp response and efficient combustion—exactly what helps an offshore boat settle into an easy cruise without feeling strained. Pair that with water (open loop) cooling and a proven offshore-ready design that’s salt water capable, and you’ve got an engine intended for long runs, changing conditions, and demanding schedules.
This F300ESB4 comes set up for confident control: remote steering control with steering assist, plus power trim to dial in running angle for varying seas and load. The 1.75:1 gear ratio turns prop power into strong acceleration and effective bite, while the 35-inch shaft makes it a natural fit for offshore transoms and applications requiring extra height.
Day-to-day ownership is made easier with smart protection built in, including a visual/audible engine alert system and emergency RPM reduction for added peace of mind. And with a stout 70-amp alternator, you’ll have the charging support to keep onboard electronics happy.
This listing is for an engine-only package: a new Yamaha F300ESB4 in Classic White, ready to be the muscle behind your next offshore setup. Ask us about current warranty coverage and rigging fitment for your hull.
