2025 Yamaha Marine F250 Mechanical

The next generation of Yamaha V6 four strokes. They're quicker, stronger, smarter and lighter - with class-leading 4.2L displacement that outperforms comparable four strokes on time-to-plane, cruise speed, weight - even fuel economy.

Features may include:

• From the top of the cowling to the tip of the prop shaft, every ounce of weight savings has been realized for maximum performance without sacrificing durability. There's even a new advanced polymer composite lower engine pan that lowers weight and increases corrosion resistance.

• Throttle response and acceleration: Yamaha's Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-rpm ranges. This feature helps Yamaha's new 4.2-litre big-bore V-6 Offshore Outboard to deliver awesome hole shot and mid-range acceleration you have to feel to believe.

• Yamaha's Variable Camshaft Timing system advances and retards the angle of the intake camshaft to dramatically increase power and throttle response in the low- and mid-rpm ranges. This feature helps Yamaha's new 4.2-litre big-bore V-6 Offshore Outboard to deliver awesome hole shot and mid-range acceleration you have to feel to believe.

• Yamaha V6 Offshore 4.2 Liter is up to 19% faster at cruise rpm than other competitive four-stroke outboards. Cruise rpm is where most offshore outboards are typically operated, meaning you get there faster, using less fuel, than competitive models.

• All Yamaha V-6 Offshore Outboards feature a proven cowling drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that trap and drain water before it enters the engine's intake, for maximum reliability.

• Yamaha V-6 Offshore Outboards feature an exhaust pressure reduction system, which not only helps keep the propeller hub cooled from hot exhaust gases, it also helps provide more power by helping to force those gases out of the engine.

• Yamaha V6 Offshore models come standard with dual pairs of water inlets, for increased cooling efficiency. Located on the front and both sides of the lower unit, each pair of pick-ups operate independently of each other to provide proper water flow in a wide variety of applications and conditions.

• Yamaha V-6 Offshore Outboards utilize a new version of our Long Span Mounting System, which employs a speciallyformulated rubber compound attached to newly-designed engine mounts. Placed as far apart vertically and horizontally as practically possible, they provide necessary strength while minimizing vibration.

• Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet, for unbelieveably smooth and quiet operation.

• Six individual sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which instantly makes the precise adjustments for optimum performance and efficiency.
