Mercury 15MLH 15HP FourStroke Manual Tiller 20″ Outboard Motor

Mercury 15HP 15MLH FourStroke Manual Long Power

Featuring a 333cc twin-cylinder engine family, the Mercury 15HP 15MLH serves as a high-torque solution for US boaters requiring a prop-rated propulsion unit with superior thermal stability. This 15HP four-stroke technology utilizes an inline-two 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 15MLH 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.
