Yamaha F6LMHA 6HP Portable Long Shaft
The Yamaha F6LMHA 6HP is a lightweight and portable 4-stroke outboard motor featuring a reliable 1-cylinder 139cc OHV engine architecture. This compact power plant is specifically designed for small tenders, canoes, and as a secondary kicker for larger vessels, weighing only 60 lbs for easy manual transport. Its 20-inch long shaft configuration provides advanced outboard engine technology with consistent propeller immersion for vessels with higher transoms requiring dependable low-speed thrust.
Portable OHV Power
The F6LMHA utilizes a single-cylinder OHV configuration to provide reliable and efficient power for displacement hulls. This mechanical design is focused on simplicity and durability, ensuring the engine remains easy to start and maintain for recreational users. Small boat owners enjoy quiet operation and reduced exhaust emissions compared to traditional two-stroke models.
Long Shaft Versatility
The 20-inch shaft length is perfectly suited for boats with a 20-inch transom, such as small aluminum sailboats or high-side utility skiffs. This length helps support the propeller remains properly submerged to prevent aeration and maintain steady forward or reverse thrust. Captains gain improved tracking and steering authority when navigating calm inland lakes or protected coastal waters.
360-Degree Steering
This 6HP outboard features a unique steering system that allows for 360-degree rotation of the motor. This provides agility when docking or maneuvering in technical river sections, as the engine can provide full thrust in any direction without shifting gears. You gain the tactile control necessary for precise maneuvers in crowded marinas or narrow channels.
Integrated Fuel System
The F6LMHA features a convenient built-in 1.1-liter fuel tank for short trips and a secondary connector for an external tank for extended excursions. This dual-fuel capability allows for a clean transom layout while providing the flexibility needed for longer fishing or exploring missions. US boaters appreciate the simplicity of a self-contained unit for short transits to shore.
Japanese Quality Standards
The Yamaha F6LMHA is protected by a comprehensive 3-year limited factory warranty backed by strict engineering standards. This protection plan helps support long-term maritime durability and covers critical structural and essential mechanical components. Owners benefit from an extensive service network and genuine Japanese parts availability for all warranty repairs.
Tender Vessel Match
The F6LMHA 6HP provides the appropriate power balance for high-transom inflatable tenders and small wooden skiffs. Its 60 lbs design allows for easy manual transport while maximizing efficiency on open water. Modern vessel owners enjoy the combination of quiet operation and legendary four-stroke performance on the water.
