Key Features & Benefits: Powering Your Command with Digital Precision and Reach

Let’s delve into the groundbreaking technologies and thoughtful engineering that make the F300USB2 an industry leader for specialized applications.

Potent 4.2L Big-Bore V6 for Unrivaled Output

At the very heart of the F300USB2 is a formidable 4.2L (4169cc) 60-degree V6 engine. This “big-bore” displacement is achieved through an advanced thermally applied plasma fusion process on the cylinder walls. This innovative process eliminates conventional steel cylinder sleeves. Instead, the cylinder walls are an impressive 60% harder than steel. Consequently, this allows for larger cylinder bores. This means significantly more power and torque without increasing outer engine dimensions. This design also contributes to lighter weight, superior cooling, and reduced internal friction. All these factors enhance both performance and long-term reliability. Therefore, expect immediate, exhilarating power delivery whenever you demand it.

Integrated Digital Electric Steering (DES) for Ultimate Control

The standout feature of the F300USB2 is its integrated Digital Electric Steering (DES). This revolutionary system completely eliminates traditional hydraulic steering hoses and pumps from the bilge. Instead, steering commands are transmitted digitally. This results in:

• Smoother, More Precise Steering: Experience effortless, highly responsive steering with minimal feedback, crucial for larger vessels.
• Cleaner Rigging: A clutter-free transom and bilge area due to the absence of hydraulic lines, enhancing aesthetics and simplifying maintenance.
• Reduced Power Consumption: DES draws less power from your batteries compared to conventional hydraulic systems.
• Enhanced Reliability: Fewer components mean less to maintain and fewer points of potential failure, crucial for offshore confidence.

This integrated design offers unparalleled control and a seamless helm experience.

Seamless Helm Master EX® Integration

The F300USB2 is fully compatible with Yamaha’s optional Helm Master EX® boat control system. This advanced system unlocks a suite of capabilities including:

• Joystick Control: Effortless docking and maneuvering in tight spaces, even with single-engine applications, especially valuable on large boats.
• Autopilot Functionality: Features like Course Hold, Heading Hold, and Track Point for precise, hands-free navigation on long runs.
• SetPoint™ Modes: StayPoint™, FishPoint™, and DriftPoint™ automatically maintain your boat’s position or heading, revolutionizing fishing and waiting at docks.
• Pattern Steer: Pre-programmed fishing patterns for precise lure presentation, maximizing your angling efficiency.

This comprehensive integration transforms your boating experience, offering unparalleled control and convenience.

Ultra-Long (30-inch) Shaft for Optimal Submersion

The 30-inch shaft length of the F300USB2 is specifically designed for boats with very high transoms. This extended length ensures the propeller remains properly submerged, even in rough seas or when the boat is heavily loaded. This maintains consistent thrust and efficiency, preventing ventilation and maximizing performance on vessels that require this specialized transom height.

Exceptional Fuel Efficiency for Extended Range

Despite its commanding power, the F300USB2 boasts outstanding fuel efficiency. Its Precision Multi-Point Electronic Fuel Injection (EFI) system ensures precise fuel metering. It optimizes combustion for excellent economy. This intelligent system, combined with friction-reducing micro-textured cylinder walls, delivers superb fuel economy across the entire RPM range. Thus, you can extend your cruising range. Spend more time enjoying the water, and less time at the fuel dock.

High-Output Charging for Extensive Electronics

Modern, well-equipped boats demand substantial electrical power. The F300USB2 impressively produces up to 70 gross amps of charging power. This ample output reliably powers your growing array of onboard electronics. This includes multiple fish finders, sophisticated navigation systems, and other high-demand accessories. Furthermore, this ensures all your critical systems remain fully operational throughout your longest trips.

Smooth, Quiet, and Refined Operation

Yamaha engineers have meticulously refined the F300USB2 for an impressively smooth and quiet boating experience. Engine exhaust gases are strategically routed. They pass through a labyrinth of passages. Then, they exit via an idle exhaust relief outlet, significantly reducing sound. The design minimizes vibration and noise, creating a more comfortable and enjoyable time on the water, even during extended journeys.

Built for Unwavering Durability and Smart Maintenance

The F300USB2 is inherently built tough. It withstands the rigors of heavy use and harsh marine environments. Its advanced cowling drain system efficiently drains any water. This protects crucial internal components. Incoming air routes through a labyrinth of passages. These effectively trap and drain water, ensuring maximum reliability. Additionally, the outboard features Thrust Enhancing Reverse Exhaust (TERE). This innovative system keeps exhaust bubbles away from the propeller. This occurs below 2500 RPM and when in reverse. This means the prop bites only clean water, resulting in outstanding reverse thrust and control. This is especially helpful when backing down on fish or maneuvering in tight spaces.

For ultimate convenience, the F300USB2 includes Yamaha’s exclusive TotalTilt™ Feature. A swift double-tap of the trim button performs a full tilt up or down. This makes trailering and shallow water navigation incredibly quick. This feature is also handy for propeller changes or docking.
