Decoding the F6SMHA Model Code: Feature-Packed Portability

The “SMHA” in the Yamaha F6SMHA model designation precisely defines its characteristics:

• S: Short Shaft (typically 15 inches). This length is ideal for smaller boats with low transoms, ensuring optimal propeller depth and performance.
• M: Manual Start. This signifies that the engine is started using a pull cord.
• H: Tiller Handle. This indicates that the engine is controlled directly from the tiller handle (throttle and steering), rather than remote controls.
• A: (Often refers to a specific generation or series within the F6 lineup, indicating updates or refinements, or sometimes “built-in” fuel tank, which is a standard feature on this model).

Therefore, the F6SMHA is specifically engineered for boaters who prioritize strong portability, straightforward manual operation, and direct, hands-on control of their small craft, with the added benefit of flexible fueling options.

Why the Yamaha F6SMHA Excels: Enhanced Power with Maximum Versatility

For boaters who require a genuinely portable yet more powerful outboard than the 4 HP models, the Yamaha F6SMHA truly shines.

Optimal Power-to-Weight Ratio

Primarily, at 6 horsepower and weighing in at a mere 60 pounds (27 kg), the F6SMHA offers an exceptional power-to-weight ratio for its class. This provides robust thrust for larger tenders, small aluminum boats, or even navigating stronger currents, while remaining highly manageable for transport and mounting.

Smart Storage System

Moreover, a standout feature shared with other Yamaha portables is its oil-leak prevention system for on-side storage. This clever design allows the engine to be laid down on its front, left, or right side without oil leakage, eliminating concerns about messy spills and making storage in tight spaces or vehicle trunks hassle-free. It also includes built-in carry handles and resting pads for added convenience.

Flexible Fueling Options for Extended Range

A key advantage of the F6SMHA is its dual fuel system. It comes with a convenient built-in 0.29-gallon (1.1-liter) see-through fuel tank, allowing you to easily monitor fuel levels. Crucially, it also features a switchable connection for an optional external fuel tank (e.g., 3.1-gallon). This provides excellent extended range for longer excursions without needing to refuel frequently, offering significant versatility.

Effortless Manual Starting

Despite being a manual start, the F6SMHA features an ergonomic, easy-grip starter handle with a built-in decompression device for incredibly easy pull starting. This system releases cylinder pressure during cranking, significantly reducing the effort required to get the engine running. An auxiliary prime pump under the cowling also ensures smooth starts, even after long storage.

User-Friendly Tiller Control with F-N-R

The F6SMHA is equipped with a comfortable tiller handle that includes a twist-grip throttle for precise speed control. Its 180-degree steering capability provides exceptional maneuverability, allowing for very tight turns and easy docking. It also features a clear Forward-Neutral-Reverse (F-N-R) gear shift, offering more precise control and ease of handling than basic F-N only models.

Clean and Efficient Four-Stroke Power

The F6SMHA features a 139cc single-cylinder, Overhead Valve (OHV) 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, making it environmentally friendly and compliant in all 50 states.

High-Output Alternator (Optional Kit)

The F6SMHA can also offer a 6-amp alternator output, which can power small electronics or charge a battery (requires an optional charging kit). This is a useful feature for extended use or if you have basic onboard electrical needs.

Legendary Yamaha Durability

Naturally, like all Yamaha outboards, the F6SMHA benefits from Yamaha’s commitment to durability. It features a robust design with superior corrosion protection (YDC-30 alloy, 5-stage Phaze Five™ paint process, zinc coating, high-quality stainless steel) to withstand harsh marine environments, ensuring years of reliable service. Its pressurized oiling system minimizes engine wear for extra-long engine life.
