2027 Yamaha Four Stroke V6 Offshore F350USA4

Meet the 2027 Yamaha Four Stroke V6 Offshore F350USA4—a standalone, engine-only powerhouse built to turn serious hulls into confident, long-legged offshore runners. Finished in Classic White, this outboard looks right at home on modern center consoles, offshore walkarounds, and big bay boats that demand real muscle at the transom.
At the heart of this Yamaha is a 4.3L V6, 24-valve DOHC four-stroke design (that’s 4 valves per cylinder across 6 cylinders) tuned to deliver 350 bhp (261.2 kW) with peak output at 6000 RPM and a full-throttle operating range of 5000–6000 RPM. Translation: it’s built for the kind of hulls that need strong acceleration onto plane, confident midrange punch for carrying load, and the top-end authority to stay efficient and composed when conditions—and miles—stack up.
Fueling is modern and precise thanks to fuel injection, sipping mid grade gas and helping keep cruise efficiency in the conversation when you’re covering water, not just idling around it. Cooling is handled by water (open loop), and it’s explicitly salt water capable, making it a solid choice for coastal and offshore duty.
This model is set up for big-water control and convenience: electric start, power trim, and remote outboard steering control with a steering assist system help reduce fatigue during long runs and frequent course corrections. The 1.75:1 gear ratio pairs well with propeller-driven setups where strong bite and efficient transfer of power matter.
For peace of mind, Yamaha includes a visual/audible engine alert system, and if things get critical, emergency RPM reduction is there to help protect the engine.
It’s also ready to support today’s onboard electronics with a stout 70-amp alternator, and with its 30-inch shaft and 642 lb (291 kg) dry weight, it’s aimed squarely at offshore transoms designed for extra-long-shaft power.
If you’re shopping for a new offshore outboard that blends big displacement torque, 350-horse capability, and Yamaha four-stroke refinement—in a clean Classic White package—this F350 is ready to be the heart of your next build or repower. Warranty coverage varies by dealer/program—ask us for the current Yamaha warranty details on this engine.
