Mercury 3.5HP 3.5MH – Portable 4-Stroke 15in

Mercury 3.5HP 3.5MH Portable Short Shaft Power

Featuring an 85cc single-cylinder engine family, the Mercury 3.5HP 3.5MH serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 3.5HP four-stroke technology utilizes a lightweight OHV architecture to minimize internal friction, effectively converting internal combustion into efficient thrust for square-stern canoes and small tenders. The 15-inch short shaft design provides an optimized center of gravity, while the manual decompression system and twist-grip throttle ensure immediate, one-pull starts across diverse inland and coastal environments.

Operational longevity of the 3.5MH model is secured through a specialized water-cooled system featuring a splash lubrication architecture to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs an integral fuel tank that eliminates the need for external hoses, while the Mercury XK360 alloy science utilizes a multi-layer finish to mitigate oxidation in high-salinity waters. With a 3-year/300-hour service interval and an ergonomic carry handle, this fuel-efficient outboard provides superior ownership value for boaters seeking a lightweight, low-emission engine with versatile shallow-water drive positions.
