Decoding the F8LMHB Model Code: Long-Shaft Versatility and Key Features

The “LMHB” in the Yamaha F8LMHB model designation precisely defines its characteristics:

• L: Long Shaft (typically 20 inches, or approximately 562 mm / 22.1 inches). This shaft length is vital for boats with higher transoms, guaranteeing the propeller is adequately submerged, which prevents cavitation and optimizes performance, particularly in choppy waters.
• M: Manual Start. This indicates that the engine is started using a traditional pull cord.
• H: Tiller Handle. This signifies that the engine is controlled directly via the tiller handle, which integrates throttle and steering functions.
• B: (This suffix often denotes a specific generation or series within the F8 lineup, indicating updates or refinements, such as the new shorter tiller handle design).

Therefore, the F8LMHB is meticulously engineered for boaters who prioritize a long shaft, substantial portable power, straightforward manual operation, and direct, hands-on control of their craft, all while benefiting from both integrated convenience and flexible fueling solutions.

Why the Yamaha F8LMHB Excels: Robust Power and Long-Shaft Specific Advantages

For boaters who require a genuinely portable yet powerful outboard with the critical advantage of a long shaft, the Yamaha F8LMHB truly stands out.

Long Shaft for Optimal Performance

The 20-inch long shaft is a key differentiator, making the F8LMHB ideal for boats designed with higher transoms, such as many sailboats (as auxiliary power), larger rigid inflatable boats (RIBs), or certain larger aluminum fishing boats. This extended shaft ensures the propeller operates at the optimal depth, preventing ventilation (when the propeller pulls air from the surface) and improving thrust, efficiency, and maneuverability, especially in waves or when the boat is loaded.

Powerful and Efficient Engine

Primarily, the F8LMHB is driven by a 212cc SOHC (Single Overhead Camshaft) two-cylinder four-stroke engine. This larger displacement (7.5% more than its previous design) delivers a robust 8 horsepower at the prop shaft, providing significant thrust for better acceleration and faster speeds, even when carrying loads. This makes it ideal for more demanding small boat applications.

Optimal Power-to-Weight Ratio

Crucially, weighing in at just 89 pounds (40 kg), the F8LMHB offers an impressive power-to-weight ratio for an 8 HP long-shaft outboard. This balance ensures it’s powerful enough to get the job done, yet remains manageable for carrying, mounting, and removing from your boat.

Smart Storage and Portability Features

Moreover, a standout feature carried over from other Yamaha portables is its oil retention system for on-side storage. This ingenious design allows the engine to be laid down on its front, left, or right side without oil leakage, eliminating concerns about messy spills in a car trunk, boat locker, or garage. It also includes newly designed built-in front and rear carry handles and resting pads for enhanced convenience. The new shorter tiller handle also folds back tighter to the cowl for more secure and compact storage.

Flexible Fueling Options for Extended Range

A significant advantage of the F8LMHB is its dual fuel system. It features a convenient built-in 0.29-gallon (1.1-liter) see-through fuel tank, allowing you to easily monitor fuel levels. Crucially, it also includes a switchable connection for an optional external fuel tank (e.g., a 3.1-gallon tank). This provides excellent extended range for longer excursions, eliminating the need for frequent refueling and offering substantial operational flexibility.

Effortless Manual Starting

Despite being a manual start, the F8LMHB features an ergonomic, easy-grip starter handle with a built-in automatic decompression device. This system efficiently releases cylinder pressure during cranking, significantly reducing the effort required for quick and reliable pull starts. An auxiliary prime pump located under the cowling further ensures smooth starts, even after periods of long storage.

User-Friendly Tiller Control with F-N-R and New Design

The F8LMHB is equipped with a comfortable, newly designed shorter tiller handle that includes a twist-grip throttle for precise speed control. This shorter handle makes operation more comfortable and improves storage compactness. Its 43-degree steering angle (from center, either direction) provides exceptional maneuverability, making tight turns and docking simple. It also features a clear Forward-Neutral-Reverse (F-N-R) gear shift, offering precise control and ease of handling.

Clean, Smooth, and Efficient Four-Stroke Power

The F8LMHB features a 212cc two-cylinder, SOHC four-stroke engine. This design ensures exceptionally quiet, smooth, and fuel-efficient operation with ultra-low emissions. It boasts a 3-Star C.A.R.B. (California Air Resources Board) rating, signifying its environmentally friendly performance and compliance with stringent emissions standards in all 50 states. Its streamlined intake and intake silencer contribute to minimum noise and maximum power.

High-Output Alternator (Optional Kit)

The F8LMHB offers a solid 6-amp alternator output, which can power small electronics or charge a battery (requires an optional charging kit). This is a valuable feature for extended use or if you have basic onboard electrical needs.

Legendary Yamaha Durability and Corrosion Protection

Naturally, like all Yamaha outboards, the F8LMHB benefits from Yamaha’s commitment to durability. It features a robust design with superior corrosion protection, including Yamaha’s unique YDC-30 aluminum alloy, a 5-stage Phaze Five™ paint process, zinc coating, and high-quality marine-grade stainless steel components, all designed to withstand harsh marine environments and ensure years of reliable service. Its pressurized oiling system further minimizes engine wear for extended engine life. A freshwater flushing system allows for easy rinsing of salt and dirt without running the engine.

Perfect Applications for Your Yamaha F8LMHB 8 HP Outboard

The Yamaha F8LMHB is an excellent choice for a variety of small to medium-sized craft where substantial portable power, ease of use, and versatility are essential, particularly with a long shaft:

• Sailboat Auxiliaries / Kickers (for small to medium sailboats): Crucially, the long shaft is often a necessity for sailboats to ensure the propeller remains submerged and efficient, especially in choppy conditions or when the boat heels. The F8LMHB provides robust auxiliary power for maneuvering in and out of harbors or against stronger winds.
• Larger Inflatable Boats and Tenders: Indeed, its power, portability, and F-N-R shifting make it an ideal primary or auxiliary motor for getting ashore quickly or for longer runs, particularly for tenders designed with higher transoms.
• Small to Medium Aluminum Fishing Boats (e.g., Jon Boats, Small V-Hulls with higher transoms): Furthermore, it provides robust and efficient propulsion for fishing in lakes, rivers, and calm bays, offering enough power for faster trolling, getting to distant spots, or handling currents, especially where a long shaft might be necessary due to transom design.
• Multi-species Fishing Boats (as a Kicker): The F8LMHB is a very popular choice as a “kicker” motor for larger fishing boats, providing quiet, fuel-efficient trolling power that larger main engines cannot match, and the long shaft ensures it stays submerged on higher transoms.
• Small Utility Boats: Moreover, it’s excellent for various light-duty utility tasks on ponds, lakes, or protected waters, where reliable power and a long shaft are needed.
