Decoding the F40LA Model Code

The “LA” in the Yamaha F40LA model designation precisely defines its characteristics.

Long Shaft (“L”)

Specifically, the “L” signifies a Long Shaft (20 inches, or approximately 536 mm). This shaft length is vital for boats with higher transoms. It ensures the propeller is adequately submerged. This, in turn, prevents cavitation and optimizes performance, particularly in choppy waters.

Remote Control (“A” for Mechanical Remote)

Next, the “A” in F40LA, when distinct from “H” (tiller handle), typically indicates that the engine is configured for Remote Mechanical Control. This means it is operated from a helm station using mechanical throttle and shift cables, and often comes with a remote key switch.

Model Series (Implied “A”)

Finally, the “A” suffix, often associated with the model number itself, frequently indicates a specific generation or series within the F40 lineup. It signifies updates, refinements, or consistent feature sets across the model range.

Therefore, the F40LA is meticulously engineered for boaters who prefer a long shaft, significant power, the convenience of electric starting, and precise control from a remote helm station, often with Power Trim & Tilt.

Why the Yamaha F40LA Excels: Key Advantages

For boaters requiring a genuinely powerful yet lightweight outboard with the critical advantage of a long shaft, the luxury of electric start, remote control, and advanced features, the Yamaha F40LA truly stands out.

Responsive and Efficient Three-Cylinder Engine

Primarily, the F40LA is driven by a 747cc SOHC (Single Overhead Camshaft) three-cylinder four-stroke engine. Consequently, this large displacement boasts excellent low-down torque and robust mid-range power. It delivers a powerful 40 horsepower at the prop shaft (at 5500 RPM). Moreover, this provides significant thrust for quick hole shots, better acceleration, and higher speeds, even when carrying heavier loads. Therefore, it is ideal for a wider range of small to medium-sized boat applications.

Electronic Fuel Injection (EFI) for Superior Performance

Indeed, a key enhancement in the F40LA is its Electronic Fuel Injection (EFI) system. As a result, this multi-point EFI system, controlled by an Engine Control Module (ECM), precisely meters fuel to each cylinder. Consequently, this leads to dependable, “first-time, every-time” hot and cold starts. Furthermore, it ensures improved fuel efficiency, smoother acceleration, and excellent throttle response across the entire RPM range.

Long Shaft for Optimal Water Depth

Crucially, the 20-inch long shaft is a defining feature. It makes the F40LA perfect for boats designed with higher transoms. For instance, many deep-V aluminum boats, pontoon boats, or certain larger rigid inflatable boats (RIBs) benefit from this feature. Thus, this extended shaft ensures the propeller operates at the optimal depth. This prevents ventilation and improves thrust, efficiency, and maneuverability, especially in waves or when the boat is loaded.

Optimal Power-to-Weight Ratio and Design

Furthermore, weighing approximately 98 kg (214 lbs), the F40LA strikes an excellent balance between power and portability for a 40 HP electric start long-shaft outboard with EFI and Power Trim & Tilt. This ensures it’s powerful enough for diverse uses, yet remains manageable for mounting and removal, offering a solid weight advantage in its class.

Effortless Electric Start and Power Trim & Tilt

Moreover, the electric start system provides unparalleled convenience. Simply put, manual pull-starting is completely eliminated; a simple turn of a key or push of a button brings the engine to life. As a result, this makes operation much easier, especially in unpredictable conditions. Additionally, the Power Trim & Tilt system allows for instant, push-button adjustment of the engine angle. This optimizes boat performance, improves acceleration, allows for easy navigation in shallow water, and makes trailering simple.

Precise Remote Mechanical Control

The F40LA is designed for remote mechanical control from a helm station. Consequently, this setup provides precise and comfortable control over steering, throttle, and gear shifting. Thus, it’s ideal for boats with steering consoles or side consoles where direct tiller operation is not preferred or practical. This allows for clear forward visibility and a more integrated boating experience, with optional Command Link® gauge compatibility for real-time data.

Clean, Smooth, and Quiet Four-Stroke Power

The F40LA features a 747cc three-cylinder, SOHC four-stroke engine. As a result, this design ensures exceptionally quiet, smooth, and fuel-efficient operation with ultra-low emissions. In addition, it boasts a CARB 2-Star Rating, signifying its environmentally responsible performance. Ultimately, features like its single throttle valve, long intake manifold, and through-propeller exhaust contribute to its remarkably quiet operation.

High-Output Alternator for Onboard Power

Significantly, the F40LA offers a robust 16-17 amp alternator output (12V – 17A), which is ample for powering onboard electronics and reliably charging your battery (with an included rectifier/regulator). This is a crucial feature for electric start models, ensuring your battery is always ready.

Legendary Yamaha Durability and Corrosion Protection

Naturally, like all Yamaha outboards, the F40LA benefits from Yamaha’s commitment to durability. Indeed, it features a robust design with superior corrosion protection. This includes Yamaha’s unique YDC-30 aluminum alloy, a 5-stage Phaze Five™ anti-corrosive paint process, multiple sacrificial anodes, zinc coating, and high-quality marine-grade stainless steel components. All these elements are designed to withstand harsh marine environments and ensure years of reliable service. Furthermore, its pressurized oiling system minimizes engine wear for extended engine life. Plus, a freshwater flushing system allows for easy rinsing of salt and dirt without running the engine.
