Pre-owned Yamaha F-300 UCA, 30" inch shaft, motor!
Smarter. Stronger. Lighter. Faster. More Fuel Efficient. The next generation of offshore outboard power.
Power and Performance
4.2 Liter Big-Bore Displacement: By using a highly advanced, thermally applied plasma fusion process on the cylinder walls, Yamaha's new line of V6 Offshore outboards have no conventional steel cylinder sleeves, yet the cylinder walls are 60% harder than steel. That means larger cylinder bores for increased displacement, resulting in more power and torque, without increasing outer cylinder dimensions. It also results in dramatically lighter weight, better cooling, and "micro-textured" cylinder walls that help decrease friction loss, and further increase performance and enhance reliability.
Lightest Weight In Class: 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.
Best-In-Class Fuel Efficiency: Yamaha's V6 Offshore outboard has up to 17% better long-range fuel economy at 3,500 rpm than other 300hp 4-stroke outboards. All air entering the engine block of each Yamaha V6 Offshore outboard is routed through a single 75mm electronically controlled throttle valve. Working in concert with the Precision Multi-Point Fuel Injection System, together they help ensure the precise amount of air and fuel necessary for optimum power and fuel efficiency.
Cruising Speed: 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.
Power Yet Compact: Yamaha’s exclusive “In-Bank” exhaust system exits downward through the center of the engine between the “V” of the cylinders, rather than on the exterior side. This increases combustion efficiency for more power and torque, and also provides for a more compact shape.
Reliability and Durability
Protection From The Elements: 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.
Protection and Power: 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.
Cleaner Fuel: Yamaha's V6 Offshore outboards utilize a large, on-engine water separating fuel filter with a water sensor. Used in conjunction with Yamaha's 10-Micron Water Separating Fuel Filter, it helps separate water and contaminants from the fuel before they can reach the outboard’s other filters and fuel injectors.
Increased Cooling Capacity: 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.
Reliability and Efficiency: 4.2 litres of class-leading displacement teams with individual intake and exhaust camshafts to provide more precise valve timing control with fewer moving parts than conventional rocker arm systems for increased reliability. This superior design also allows for use of 4 valves per cylinder which exchange intake and exhaust gases more efficiently for responsive power and increased fuel economy.
Convenience and Control
Command Link Plus Compatible: Yamaha V6 Offshore outboards are compatible with Yamaha's new Command Link Plus rigging system. Featuring a new 5" high-contrast, multi-engine, LCD display; new Command Link Plus Digital Electronic Controls; new key switches and start/stop panels; and new Command Link Plus accessories, this system offers more convenience, flexibility, and information than ever before. There's even the optional new Y-COP™ Immobilizer system, allowing operators to disable the ignition system from the key fob during periods of non-use.
Best-In-Class Charging Power: With 70 amps of total alternator output, Yamaha's new V6 Offshore outboards have over 29% higher total alternator power than other V6 four-stroke outboards. That kind of charging power is vital to help operate today's wide array of on-board electronic devices.
Shift Dampener System (SDS™): Yamaha's patented new Shift Dampener System (SDS) greatly reduces noise commonly associated with shifting gears. Using a special new design and components, much of the resulting force is absorbed, resulting in far quieter and smooth operation. Initially available on Saltwater Series II™ - SDS propellers, which are ideal for these outboards and their typical applications.
Variable Trolling RPM: Controlled by a Command Link Plus digital display or a Command Link tachometer, the operator can adjust the engine's trolling speed from 600 ~ 1000 rpm, in 50-rpm increments. This helps provide precise and consistent trolling speeds in a wide array of conditions.
Vibration Reduction: Yamaha V-6 Offshore Outboards utilize a new version of our Long Span Mounting System, which employs a specially formulated 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.
Smooth and Quiet: Engine exhaust is routed through a maze before exiting above the waterline through the idle exhaust relief outlet, for unbelievably smooth and quiet operation.
Turn-Key Efficiency: 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.
