Deciphering the VF115XB Model Code

The “VF115XB” designation provides crucial information about this Yamaha outboard.

The “V” for VMAX SHO Series

First, the “V” denotes that this is a VMAX SHO (Super High Output) model. Yamaha specifically engineers this series for performance applications. It delivers aggressive acceleration and a strong top end. This makes it ideal for competitive fishing or recreational boating demanding quick response.

The “F” for Four-Stroke Engine

Next, the “F” indicates a Four-Stroke engine. This means the engine operates on a cleaner, more fuel-efficient four-stroke cycle, contrasting with two-stroke engines.

The “115” for Horsepower

Then, the “115” simply denotes the 115 horsepower rating at the prop shaft.

The “X” for Extra-Long Shaft

Furthermore, the “X” signifies an Extra-Long Shaft (25 inches, or approximately 643 mm). This shaft length is crucial for boats with higher transoms. It ensures the propeller is adequately submerged for optimal thrust and performance, particularly in choppier conditions.

The “B” for Mechanical Remote Control

Finally, the “B” in VF115XB indicates that the engine is configured for Remote Mechanical Control. This means it operates from a helm station. It uses traditional mechanical throttle and shift cables.

Therefore, the VF115XB is a VMAX SHO four-stroke, 115 horsepower outboard with a 25-inch extra-long shaft, designed for remote mechanical control.

Why the Yamaha VF115XB Excels: Key Advantages

The Yamaha VF115XB stands out for boaters. It prioritizes raw power, efficiency, and advanced features in a lightweight package, specifically for applications requiring an extra-long shaft.

Big-Bore 1.8L DOHC Engine for Class-Leading Performance

Primarily, the VF115XB is powered by a 1.8-liter (1832cc) in-line four-cylinder, 16-valve, DOHC (Double Overhead Camshaft) four-stroke engine. This “big-bore” displacement is typically found in higher horsepower models. Consequently, it provides superior torque and acceleration, especially off the line. This makes the VF115XB a class leader in terms of hole shot and top speed among 115 HP outboards. Yamaha states it is their fastest 115 HP four-stroke ever.

Incredibly Lightweight Design

Despite its larger displacement, the VF115XB is remarkably lightweight. It weighs approximately 180 kg (397 lbs). This makes it one of the lightest 115 HP four-stroke outboards available, even with the extra-long shaft. As a result, it enhances boat performance, allows for faster planing, improves handling, and reduces stress on the transom.

Electronic Fuel Injection (EFI) for Precision

A core feature is its Multi-Point Electronic Fuel Injection (EFI) system. This precise system, controlled by an Engine Control Module (ECM), accurately meters fuel. Consequently, you get dependable “first-time, every-time” starts, both hot and cold. Moreover, it ensures superior fuel efficiency, smoother acceleration, and excellent throttle response across the entire RPM range.

Effortless Electric Start and Power Trim & Tilt

The electric start system offers unmatched convenience. Simply turn a key, and the engine comes to life. This eliminates manual pull-starting. Additionally, the Power Trim & Tilt system allows for instant, push-button adjustments of the engine angle. This optimizes boat performance, helps navigate shallow water, and simplifies trailering. A built-in tilt stop lever also helps prevent accidental damage.

Precise Remote Control with Digital Compatibility

The VF115XB is designed for remote mechanical control from a helm station. This setup provides precise and comfortable control over steering, throttle, and gear shifting. Thus, it’s ideal for boats with steering consoles. Furthermore, it’s compatible with Yamaha’s optional Digital Network Gauges (e.g., Command Link®). These gauges provide real-time engine data, fuel management, and NMEA2000 compatibility, enhancing control and efficiency.

Smooth, Quiet, and Fuel-Efficient Operation

The VF115XB’s 1.8-liter four-cylinder DOHC engine ensures remarkably quiet, smooth, and fuel-efficient operation. It also produces ultra-low emissions. This unit holds a CARB 3-Star Rating, signifying its environmentally responsible performance. In addition, features like its offset crankshaft, single bore throttle body, improved engine rigidity, and Labyrinth Exhaust System contribute to minimal noise and vibration.

High-Output Alternator

Significantly, the VF115XB features a powerful 35-amp alternator output (12V). This provides ample power for all your onboard electronics. It also reliably charges your battery. Even at idle, the alternator produces strong, stable output (up to 27 amps at 1000 RPM).

Legendary Yamaha Durability

Like all Yamaha outboards, the VF115XB is built for durability. It features robust materials and superior corrosion protection. This includes Yamaha’s proprietary YDC-30 aluminum alloy. It also has a 5-stage Phaze Five™ anti-corrosive paint system, multiple sacrificial anodes, and high-quality stainless steel components. All these elements ensure longevity in harsh marine environments. Moreover, a freshwater flushing system allows for easy rinsing, further extending engine life.

Variable Trolling RPM Control (VTS®)

The VF115XB also offers Variable Trolling RPM Control (VTS®). This feature lets you precisely adjust trolling speeds in 50-RPM increments (from 550 to 1000 RPM). This is done via an optional Digital Network Tachometer or a remote VTS switch. This is invaluable for anglers who need to fine-tune lure presentation.
