Mercury 15EH 15HP FourStroke Electric Tiller 15″ Outboard Motor

Mercury 15HP 15EH FourStroke Electric Short Power

Technology driven and built upon a 333cc twin-cylinder engine family, the Mercury 15HP 15EH 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 mechanical vibration, effectively converting internal combustion into efficient thrust for rigid-hull inflatables and small coastal skiffs. The 15-inch short shaft design provides an optimized center of gravity, while the electric start system and auto-compression release ensure immediate, push-button ignition across diverse inland and coastal environments.

Operational longevity of the 15EH 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 12A 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 five trim positions including shallow water drive, this fuel-efficient outboard provides superior ownership value for boaters seeking a reliable, low-emission engine with automated starting convenience.
