Mercury 25MLH 25HP FourStroke Manual 20″ Outboard Motor

Mercury 25HP 25MLH FourStroke Manual Long Power

Featuring a 500cc three-cylinder engine family, the Mercury 25HP 25MLH serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 25HP four-stroke technology utilizes a lightweight three-cylinder architecture to minimize internal friction and maximize hole-shot performance for high-transom utilities and fishing skiffs. The 20-inch long shaft design provides an optimized center of gravity for deeper hulls, while the manual recoil with battery-free EFI ensures immediate, one-pull ignition across diverse inland and coastal environments.

Operational longevity of the 25MLH model is secured through a specialized pressurized lubrication system featuring a high-capacity oil sump to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a vapor-free fuel induction system that eliminates the need for a battery, 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 multi-function tiller, this fuel-efficient outboard provides superior ownership value for boaters seeking a lightweight, low-emission engine with manual simplicity.
