Yamaha F6LMHA Outboard Motor

20-Inch Shaft | Tiller Handle | Manual Start | Manual Tilt | Gray

Shop the Yamaha F6LMHA 6 HP portable four-stroke outboard for compatible sailboats, skiffs, inflatables, tenders, and other small boats that require a 20-inch shaft. This F6 configuration uses tiller steering, manual start, manual tilt, a carbureted 139 cc single-cylinder engine, forward-neutral-reverse shifting, and an integral fuel tank. Before ordering, confirm the boat's horsepower and engine-weight limits, transom height, shaft requirement, fuel setup, propeller, carrying and storage needs, and the exact model selected on this page.

The F6LMHA is the long-shaft version of Yamaha's 6 HP portable F6. Yamaha lists the F6 family at approximately 60 to 61 lb depending on shaft length; confirm the current weight for the selected F6LMHA configuration before ordering. Built-in carrying points, resting pads, and Yamaha's Easy Storage Oil Retention System support portable use and Yamaha-approved on-side storage. The F6 can also use an external fuel tank in addition to its integral tank when the application calls for additional fuel capacity.

Part Number and Compatibility

Model code: F6LMHA. Select this model only when the boat requires the 20-inch-shaft Yamaha F6 configuration. The F6SMHA uses the same 6 HP portable F6 platform but has a 15-inch shaft, so the two models should not be treated as interchangeable when matching the motor to a transom.

F6LMHA or F6SMHA? Choose F6LMHA when the boat calls for a 20-inch shaft. Choose F6SMHA when the manufacturer specifies a compatible 15-inch transom. Shaft length should be selected from the boat's transom and mounting requirements, not from boat length alone.

For broader comparison, browse Yamaha FourStroke 2.5-25 HP portable outboards or the full Yamaha Outboard Motors range. If the boat is rated for substantially more power than the portable range, compare Yamaha 30-115 HP Midrange Outboards rather than selecting an F6 by boat size alone.

After selecting the correct engine, verify the appropriate Yamaha outboard propeller, use OEM Yamaha outboard parts for model-specific replacement needs, and follow the Yamaha outboard service schedule together with the owner's manual for maintenance planning.
