Decoding the F70LA Model Code

The “LA” in the Yamaha F70LA model designation precisely defines its characteristics.

Long Shaft (“L”)

Specifically, the “L” signifies a Long Shaft (20 inches, or approximately 534 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 F70LA, 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 typically comes with a remote key switch.

Therefore, the F70LA 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, complete with Power Trim & Tilt.

Why the Yamaha F70LA Excels: Key Advantages

For boaters requiring a genuinely powerful yet remarkably lightweight outboard with the critical advantage of a long shaft, the luxury of electric start, remote control, and advanced features, the Yamaha F70LA truly stands out.

Innovative Four-Cylinder SOHC Engine for Lightweight Power

Primarily, the F70LA is driven by a unique 996cc, 16-valve, SOHC (Single Overhead Camshaft) in-line four-cylinder four-stroke engine. Consequently, this advanced design utilizes a single overhead camshaft to actuate 16 valves, rather than the heavier dual camshaft setup often found on 16-valve engines. As a result, this reduces weight significantly, making the F70LA one of the lightest in its class (around 114 kg / 253 lbs). Moreover, this larger displacement and multi-valve design provides exceptional low-down torque, strong mid-range acceleration, and impressive top-end performance, delivering a robust 70 horsepower at the prop shaft (at 5800 RPM).

Electronic Fuel Injection (EFI) for Superior Performance

Indeed, a critical enhancement in the F70LA is its Multi-Point Electronic Fuel Injection (EFI) system. As a result, this precise system, controlled by a Micro-computer ECM, accurately meters fuel to each cylinder. Consequently, this leads to dependable, “first-time, every-time” hot and cold starts. Furthermore, it ensures superior 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 F70LA perfect for boats designed with higher transoms. For instance, many deep-V aluminum boats, pontoon boats, or certain larger fiberglass runabouts 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.

Unmatched Power-to-Weight Ratio

Furthermore, weighing approximately 114 kg (253 lbs), the F70LA boasts an exceptional power-to-weight ratio for a 70 HP four-stroke. This ensures it’s light enough to be mounted on a wide range of boats without compromising performance or hull integrity, while still providing ample power for diverse activities.

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 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 with Digital Gauge Compatibility

The F70LA 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. Furthermore, it is compatible with Yamaha’s optional Digital Network Gauges (e.g., Command Link®), which provide real-time engine performance data, fuel management, and other vital information, enhancing control and efficiency.

Clean, Smooth, and Quiet Four-Stroke Power

The F70LA’s 996cc four-cylinder, 16-valve SOHC engine ensures exceptionally quiet, smooth, and fuel-efficient operation with ultra-low emissions. In addition, it boasts a CARB 3-Star Rating, signifying its environmentally responsible performance. Ultimately, features like its single throttle valve, “pulse-tuned” long intake tracks, and through-propeller exhaust contribute to its remarkably quiet operation and reduced vibration, even at high RPMs.

High-Output Alternator for Onboard Power

Significantly, the F70LA offers a robust 15-17 amp alternator output (12V), which is ample for powering onboard electronics and reliably charging your battery. This is a crucial feature for electric start models, ensuring your battery is always ready, even after extended periods of idling or running accessories.

Legendary Yamaha Durability and Corrosion Protection

Naturally, like all Yamaha outboards, the F70LA 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 system, 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.

Variable Trolling RPM Control

Moreover, the F70LA offers Variable Trolling RPM Control. This allows operators to precisely adjust trolling speeds in 50-RPM increments (typically between 650 and 900 RPM) via an optional Digital Network Tachometer or a remote VTS switch. This feature is invaluable for anglers who need to fine-tune their lure presentation.
