Mercury 25ELH 25HP FourStroke Electric 20″ Outboard Motor

Mercury 25HP 25ELH FourStroke Electric Long Power

Featuring a 500cc three-cylinder engine family, the Mercury 25HP 25ELH 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 vibration, effectively converting internal combustion into efficient thrust for high-transom utilities and aluminum skiffs. The 20-inch long shaft design provides an optimized center of gravity, while the electric start system and multi-function tiller handle ensure immediate, reliable ignition across diverse inland and coastal environments.

Operational longevity of the 25ELH model is secured through a specialized pressurized lubrication system featuring a high-flow oil pump to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a battery-free Electronic Fuel Injection (EFI) system paired with a 15A alternator for accessory maintenance, 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 quiet, low-emission engine with specialized transom heights.
