2018 Yamaha F300NCA Offshore 4.2L V6 F300XCA Outboard Motor

Description

Our V6 king is the 4.2-liter, award-winning F300. It is up to 73 pounds lighter than some of its rivals, weighing 562 pounds (digital) and 551 pounds (mechanical). At cruise RPM*, it’s also up to 19% quicker. It is simple to understand why it is the best option for offshore performance.

Control and Convenience
OUTSTANDING CHARGING POWER: Our V6 4.2-liter outboards can charge a variety of on-board electronic devices with a total alternator output of up to 70 amps, which is more than 29% greater than other V6 four-strokes.
PRECISE AND CONVENIENT TROLLING: You may regulate trolling speed in 50-RPM increments from 600 to 1000 RPM with our Variable Trolling RPM Switch (VTS®), ensuring steady trolling speeds under all circumstances.

ADDITIONAL DETAILS AND SECURITY: A 6-inch high contrast, multi-engine LCD or a brand-new 7-inch touchscreen display, digital electronic controls, key switches, start/stop panels, and more information and flexibility than before are all elements of the Command Link Plus®. When moored, its optional Y-COP® theft-deterrent system turns off the gasoline and ignition systems.
SMOOTH SHIFTING: The noise that is often associated with shifting is significantly reduced by our unique Shift Dampener System (SDSTM), which absorbs the force that results from moving gears.

Strength and Efficiency
4.2 LITER BIG BORE DISPLACEMENT: The sleeveless cylinder walls of Yamaha’s 4.2-liter V6 Offshore outboards are made of plasma-fused material, which is 60% harder than steel. This means that without enlarging the outer cylinder’s dimensions, larger cylinder bores will result in greater displacement and higher power and torque. Along with significantly reduced weight and improved cooling, it also produces “micro-textured” cylinder walls that reduce friction loss, boost performance, and improve dependability.

SUPERIOR FUEL EFFICIENCY: Compared to competing four-stroke V6s, our 4.2-liter V6s are up to 17% more fuel efficient at 3500 RPM. Precision Multi-Point Fuel Injection and electronically controlled throttle valves cooperate to provide a precise fuel and air mix for optimal power and efficiency. At 562 pounds (digital) and 551 pounds (mechanical), the 4.2-liter V6 is up to 73 pounds lighter than other four-stroke engines in its class.

THROTTLE RESPONSE & ACCELERATION: To significantly boost power and throttle response in the low- and mid-RPM ranges, Yamaha’s Variable Camshaft Timing technology advances and retards the angle of the intake camshaft. Yamaha’s new 4.2-liter big-bore V6 outboards provide fantastic hole shot and mid-range acceleration thanks to this feature.
* Cruise RPM is where most offshore outboards are usually operated, so you get there faster and use less fuel than competing models. The Yamaha F300 is up to 19% faster at cruise RPM than other 300-hp four-stroke outboards.
Dependability and Sturdiness

Enhanced cooling capacity: Dual pairs of water inlets are standard on Yamaha V6 4.2-liter models to improve cooling effectiveness. Each pair of pick-ups, which are situated on the front and both sides of the lower unit, functions independently of the others to ensure enough water flow under a range of circumstances and applications.
RELIABILITY & EFFICIENCY: Compared to traditional rocker arm systems, independent intake and exhaust camshafts offer more accurate valve timing control with fewer moving parts for enhanced reliability. Four valves per cylinder, which more effectively exchange intake and exhaust gases for responsive power and improved fuel economy, are also made possible by this superior design.

PROTECTION FROM THE ELEMENTS: A tried-and-true cowling drain system is built into every Yamaha V6 4.2-liter outboard to quickly and effectively remove any water that gets into the cowling while the engine is running normally. For optimum dependability, incoming air is sent through a maze of passageways that catch and release water before it reaches the engine’s intake.
VIBRATION REDUCTION: Our Long Span Mounting System, which uses a specifically made rubber compound fastened to newly developed engine mounts, is used with Yamaha V6 4.2-liter outboards. They minimize vibration while providing the required strength when positioned as widely apart as is practically possible in both vertical and horizontal directions.
