Yamaha Outboards 175HP V MAX SHO | VF175LB

Yamaha VF175LB 175 HP Four-Stroke Outboard: Compact V MAX SHO Power for Agile Performance

Are you in pursuit of an outboard that delivers impressive power, blistering acceleration, and Yamaha’s renowned reliability, all within a performance-tuned and compact package?

Perhaps your boating demands involve competitive fishing on smaller lakes or rivers, where quick hole shot and top speed are critical. Specifically, do you require a 175 horsepower engine with standard (right-hand) rotation and a standard 20-inch shaft length, perfectly suited for lower transoms found on many smaller bass, flats, and bay boats?

The Yamaha VF175LB 175 HP Four-Stroke Outboard Motor is precisely engineered to meet these high-performance and practical demands.

Indeed, the VF175LB is a prominent member of the V MAX SHO (Super High Output) family. It embodies Yamaha’s commitment to delivering a powerful yet compact and lightweight outboard, meticulously tuned for aggressive performance characteristics. Furthermore, this model features standard (right-hand, clockwise) propeller rotation, making it ideal for single-engine applications where aggressive hole shot and top speed are paramount.

Moreover, it comes with a standard 20-inch shaft (L for Long shaft in Yamaha’s naming convention for this size). This ensures optimal propeller depth for boats with lower transoms, preventing cavitation and maximizing performance on the types of hulls it’s designed for. It includes a smooth electric start system, ensuring effortless and dependable ignition. In addition, it boasts Power Trim & Tilt, allowing for quick and precise adjustments to optimize performance and navigate varying water depths.

Beyond this, the VF175LB is configured for remote mechanical control. This provides precise command from the helm while maintaining a straightforward and often lighter rigging setup. Crucially, it integrates advanced Electronic Fuel Injection (EFI) and Variable Camshaft Timing (VCT) for optimal combustion efficiency. It also includes Variable Trolling RPM Control (VTS) for anglers. Ultimately, the VF175LB delivers powerful, responsive, and exceptionally fast performance, making it a premier choice for boaters demanding a competitive edge on smaller, more agile vessels.

Deciphering the VF175LB Model Code

The “VF175LB” designation provides crucial information about this Yamaha outboard.

The “V” for V MAX SHO Series

First, the “V” uniquely identifies this as a V MAX SHO (Super High Output) series engine. This designation signifies that the engine is tuned for maximum acceleration, top-end speed, and an overall sporty performance characteristic. Therefore, it’s built for demanding applications where quick response is critical.

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. Consequently, it offers better fuel economy and reduced emissions.

The “175” for Horsepower

Then, the “175” simply denotes the 175 horsepower rating at the prop shaft.

The “L” for Long (Standard) Shaft

Furthermore, the “L” signifies a Long Shaft (20 inches, or approximately 508 mm). This shaft length is crucial for boats with standard-height transoms. Specifically, it ensures the propeller is adequately submerged for optimal thrust and performance on typical bass, flats, and smaller bay boats.

The “B” for Mechanical Remote Control (and often specific generation)

Finally, the “B” in VF175LB typically indicates its generation and signifies that the engine is configured for Remote Mechanical Control. Unlike models with integrated digital steering, V MAX SHO models prioritize a lighter, more compact design for speed-oriented hulls, and the mechanical controls offer a direct, familiar feel.

Therefore, the VF175LB is a standard (right-hand) rotation, four-stroke, 175 horsepower V MAX SHO outboard with a 20-inch long shaft. It is designed for remote mechanical controls.

Why the Yamaha VF175LB Excels: Key Advantages

The Yamaha VF175LB stands out for boaters who prioritize aggressive performance, fuel efficiency, and cutting-edge features in a lightweight and compact package, specifically for boats designed for a 20-inch transom.

Optimized for Performance: V MAX SHO Design

Primarily, the VF175LB is part of the V MAX SHO series, meaning it’s inherently tuned for performance. Consequently, it delivers exceptional hole shot and rapid acceleration, allowing boats to get on plane quickly. Indeed, this is crucial for competitive fishing or simply enjoying a spirited ride. Yamaha states the VF175 can be up to 5 mph faster than its VF150 sibling with a tournament load.

Powerful 2.8L DOHC Engine with VCT

At its core, the VF175LB is powered by a robust 2.8-liter (2785cc) in-line four-cylinder, 16-valve, DOHC (Double Overhead Camshaft) four-stroke engine. This larger displacement enhances torque and responsiveness. Moreover, it incorporates Variable Camshaft Timing (VCT) technology. Thus, VCT continuously adjusts the intake camshaft timing. This optimizes valve overlap and duration for increased power and throttle response across the entire RPM range, especially in the low and mid-range, where performance boaters often operate.

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. Furthermore, 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 helps optimize performance, trim the boat for different conditions, and navigate varying water depths. Recent models of the V MAX SHO series also include a tilt stop lever for added convenience during maintenance or storage.

High-Output Alternator

Significantly, the VF175LB features a powerful 50-amp alternator output (12V). This provides ample power for all your onboard electronics, from fishfinders to livewells. Moreover, it reliably charges your battery. Even at low RPMs (e.g., 22 amps at 600 RPM), the alternator produces strong, stable output, ensuring consistent power for demanding electronics.

Lightweight and Compact Design

Despite its power, the V MAX SHO series prioritizes a compact and lightweight design. The VF175LB weighs approximately 218 kg (480 lbs) (dry weight), making it one of the lightest in its class for the power output. This contributes to better overall boat performance, less stern squat, and potentially higher top speeds on performance hulls. Also, being a four-stroke, there’s no need for an external oil tank, freeing up valuable storage space on your boat for batteries, tackle, or other gear.

Legendary Yamaha Durability

Like all Yamaha outboards, the VF175LB 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 VF175LB also offers Variable Trolling RPM Control (VTS®). This feature lets you precisely adjust trolling speeds in 50-RPM increments (from 650 to 900 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.
